Our Top Picks

1. Biotin & Rosemary Shampoo for Hair Growth (RootStim) : Best Shampoo for Hair Growth

I picked this biotin & rosemary shampoo as my best overall because it checks all the boxes. It’s gentle, packed with natural growth boosters, and suits just about everyone. I love that it’s sulfate-free and paraben-free, so it doesn’t strip my hair or irritate my scalp. The formula infuses strands with biotin (for strength) and rosemary oil (to boost scalp circulation). It even has a touch of saw palmetto, an herbal DHT-blocker, to help combat hormonal hair thinning. In short, it’s a great everyday shampoo to fortify your hair.

One thing that reassured me is its high customer rating (4.7/5) and popularity – it’s among Amazon’s top sellers in hair regrowth shampoos amazon.co. Users report seeing fuller, shinier hair after a few weeks of use (with consistent use, best results by 8 weeks). I also appreciate the added aloe vera and ginger root in the formula, which soothe the scalp and reduce any dryness or flakes. The rosemary-mint scent is refreshing but not overpowering. Overall, this shampoo gives a nice balance of cleansing without over-drying, plus nutrients to support growth over time. It’s my go-to recommendation if you’re starting your hair growth journey and want a reliable daily shampoo.

2. Spartan Root Activator Shampoo for Men: Best Shampoo for Hair Growth

If you’re a guy dealing with thinning hair and a flaky scalp, this Root Activator Shampoo is a solid pick to consider. I was drawn to it for its focus on scalp health. It uses natural extracts like ginger root and licorice to invigorate the scalp (these ingredients give a nice tingly fresh feel). The shampoo has a pleasant, masculine scent – reviewers describe it as refreshing and not overpowering. Importantly, it’s free of harsh sulfates and heavy chemicals, so it’s gentle enough for daily use. My scalp felt clean but not stripped after washing, and over a few weeks I noticed less itchiness and dandruff.

This shampoo is marketed for men’s hair growth, and while no shampoo can magically regrow hair, it does a great job at creating a healthy environment for your hair to grow in. It cleanses away excess oil and DHT buildup on the scalp, which can contribute to hair loss. Many users report their hair looking shinier and thicker with consistent use – one analysis of customer feedback noted significant improvements in hair strength and volume, plus reduced dandruff kimola.com. The trade-off is that it’s a bit pricier, and the overall user rating is moderate (around 3.6/5). Some men didn’t see dramatic results, but others swear by it as a gentle, everyday shampoo that maintains what you have. If your scalp is sensitive or prone to flakes, this can be a helpful addition to your routine.

No harsh sulfates (gentle daily cleanse)
Fresh, subtle scent (herbal/menthol)
Adds volume and shine to thinning hair
Targets dandruff and dryness

Pros:

Soothes scalp irritation and itch
Reduces flakes (helps with dandruff)

Lathers well, rinses clean (no residue)
Suitable for daily use (non-irritating)

Cons:

Mixed reviews on hair growth efficacy
Pricey for the size (~10 oz bottle)
Marketed to men (women can use it, but scent is “for men”)
Requires patience – not a quick fix for bald spots

Best For: Men with thinning hair and scalp issues (dry, itchy scalp). It’s great if you need a gentle daily shampoo that can improve scalp condition while giving some volume to fine hair.

3. Svvimer Rice Water Hair Growth Shampoo ; Best Shampoo for Hair Growth

For those with dry or brittle hair, this rice water shampoo is a lifesaver. It’s inspired by the old-age tradition of using rice water to strengthen and beautify hair (the same trick famously used by the Yao women known for their long, healthy hair). After trying this shampoo, I was impressed with how moisturizing and softening it is. It has a milky, creamy lather that feels very nourishing on the scalp. The ingredients list is pretty premium: fermented Rice Water for vitamins and amino acids, Citrus peel (tangerine) for a fresh boost (and maybe mild scalp exfoliation), and Ginger root oil to stimulate blood flow. They’ve also added biotin and caffeine, which may help fortify strands and possibly stimulate growth at the roots bestselected.com.

I noticed my hair felt smoother and less frizzy after using this, likely due to the intense hydration and the fact it’s sulfate-free (plus free of parabens, phthalates, etc.). It’s gentle enough for everyday use and suitable for both women and men. While it’s too soon to claim it made my hair grow like crazy, I definitely see less breakage and my hair feels a bit thicker at the ends, which is a win. If you’re looking for a more natural, organic approach to hair growth, this shampoo is an excellent choice – it even markets itself as an “organic treatment” for regrowth and thinning bestselected.com. The scent is light and a bit herbal-citrusy (from the ginger and citrus). The only downsides: it’s not the cheapest, and if you have very oily hair you might find it a tad rich. But for dry, thin hair that needs strength and moisture, this is my top pick.

Buy on Amazon

Features:

Fermented Rice Water base (rich in nutrients)
Biotin & Caffeine infused for strengthening
Contains Tangerine peel and Ginger root extracts
Sulfate-free, Paraben-free, and vegan
Gentle for daily use; unisex formula

Pros:

Deeply hydrates and conditions hair
Helps reduce breakage and split ends
Gentle on scalp – no irritation
Natural ingredients (free of nasties)
Suitable for both women and men

Cons:

May be too moisturizing for very oily hair
Subtle natural scent (no strong fragrance, which some might miss)
Requires regular use (results build over time)
Mid-range price point

Best For: Dry, thinning hair that needs extra nourishment. Great if you want to strengthen and thicken your hair while also keeping it soft, hydrated, and healthy.

4. Nativo’s Hair Growth Shampoo (Biotin, Saw Palmetto & Zinc): Best Shampoo for Hair Growth

If you have fine or thin hair that needs a serious boost, Nativo’s Hair Growth Shampoo is formulated just for that. This shampoo is like a cocktail of every known hair-friendly ingredient – when I saw the label, I was amazed: Biotin, Saw Palmetto, Zinc, Panax Ginseng, Arginine, Keratin, Honey, and even a patented Trichogen complex. It’s basically designed to target multiple causes of hair thinning. Biotin and keratin strengthen the hair shaft, saw palmetto and zinc work to block DHT and balance the scalp, and various herbal extracts like Burdock root improve circulation to the follicles. (Fun fact: burdock root is traditionally used to nourish the scalp and may help reduce shedding nativosbeauty.com.) The shampoo has a light herbal scent and lathers nicely, and I found it cleanses well without over-drying.

After a few weeks, my fine hair did seem a bit fuller and less limp – it adds a bit of volume at the roots. It also made my hair feel stronger (less hair strands on my comb, which is a relief). This formula was developed with some serious thought (the company highlights Colombian natural ingredients and science-backed additives). According to the brand, it’s safe for both men and women and even for color-treated hair nativosbeauty.com. The main drawback is availability and price: it’s a bit on the higher end, and mostly sold online. Also, because it’s tackling so many things, you have to use it consistently to see the benefit (don’t expect instant miracles). However, if your hair is very fine and prone to breakage, this strengthening shampoo can make a noticeable difference in density over time. I’d call it a “multi-vitamin for your hair”.

Buy on Amazon

Features:

Biotin, Keratin, Panthenol – strengthen and thicken strands
Saw Palmetto & Zinc – DHT blockers for follicle health
Herbal blend: Burdock Root, Ginseng, Honey, Arginine
Trichogen Complex – proprietary growth blend
Unisex and color-safe formula

Pros:

Excellent for improving hair thickness (great on fine hair)
Helps reduce shedding (less hair fall reported)
Supports scalp health (antioxidants + anti-dandruff zinc)
Developed by experts (dermatologist-tested ingredients)
Free of harsh sulfates (gentle cleansing)

Cons:

On the expensive side
Only available through select sellers (often online)
Scent is herbal/medicinal (not perfumed – fine for most)
Results take time (give it a couple of months)
May not lather as much if you’re used to conventional shampoos (due to gentle formula)

Best For: Fine, thin, or brittle hair that needs a strength boost. Also suitable if you’re experiencing early hair thinning and want a shampoo with a comprehensive approach (strengthening + DHT blocking + scalp nourishment).

5. Shapiro MD Hair Growth Shampoo and Conditioner: Best Shampoo for Hair Growth

The Shapiro MD shampoo & conditioner duo is a powerhouse if you’re dealing with hormonal hair thinning (like male or female pattern baldness). It’s formulated by two dermatologists (Dr. Shapiro and Dr. Borenstein), and their whole approach is to block DHT – which is the hormone that shrinks hair follicles in genetic hair loss. The shampoo contains three key active ingredients: Saw Palmetto, EGCG (a green tea extract), and Caffeine. These have been shown in research to help counteract DHT and stimulate hair follicles new.shapiromd.com. What I appreciate is that Shapiro MD doesn’t use minoxidil in this shampoo, so it’s non-prescription and no side effects like shedding or irritation; it relies on natural DHT blockers instead. The included conditioner is a nice bonus – it’s also DHT-fighting and vegan, and it helps keep hair soft (since hair loss shampoos can sometimes be a bit drying, the conditioner balances it out).

In my experience, after about a month of use, my hair felt a little thicker at the roots and looked healthier overall. It definitely reduced the amount of hair strands I’d find in the drain. It’s not a miracle – I didn’t suddenly sprout new hair – but it slowed down my shedding and made my hair look fuller, which is what most of us want. Many users report seeing noticeably fuller hair after 2-3 months of use (patience is key). One clinical study mentioned by the brand shows significant improvement in hair density when using their system regularly. The downsides: this kit is pricey, and the bottles are not huge (about 8 oz each for a “1 month supply”). Also, you have to use both the shampoo and conditioner consistently to get the best results, which adds an extra step in the shower. However, if you’re serious about combating thinning hair, this combo is worth trying – it’s one of the best shampoo-and-conditioner for hair growth pairs on the market, especially for DHT-related hair loss.

Buy on Amazon

Features:

Saw Palmetto, Green Tea (EGCG), Caffeine formula (patented)
100% Vegan and cruelty-free
Developed by dermatologists (clinically tested)
Includes conditioner (with matching DHT-blocking ingredients)
Free of parabens and sulfates

Pros:

Effectively targets hormonal hair loss (DHT-driven)
Many users see thicker, fuller-looking hair
Conditioner leaves hair soft and manageable (important for thin hair)
Trusted brand with scientific backing
Unisex use – works for both men and women

Cons:

Expensive (premium pricing)
Requires using two products (shampoo + conditioner routine)
Mild medicinal scent (no heavy fragrance)
Results typically take a few months of consistent use
Not as useful for non-DHT hair loss (e.g., autoimmune hair loss)

Best For: Thinning hair due to DHT/hormones – such as men’s receding hairlines or women’s hormonal thinning. Also great if you want a complete shampoo+conditioner system for maximizing thickness and scalp health.

6. Svvimer Rosemary Hair Growth Shampoo: Best Shampoo for Hair Growth

Looking for an affordable gem? This Svvimer Rosemary Hair Growth Shampoo has been a game-changer for many, and it won’t break the bank. In fact, it’s often under $20 and has over 800 five-star ratings on Amazon instyle.com. Shoppers (and I) call it a “miracle in a bottle” because it’s enriched with rosemary oil, biotin, tea tree oil, and mint – a fantastic combo for stimulating hair growth and improving scalp health instyle.com. Rosemary oil is the star here; some research even suggests rosemary can yield results comparable to minoxidil (a common hair loss treatment) after six months instyle.com. That’s pretty encouraging for a natural ingredient! Meanwhile, tea tree and peppermint help keep the scalp clean and can reduce itchiness or flakes by improving circulation and reducing dryness instyle.com.

When I used this shampoo, the first thing I noticed was the refreshing cool sensation from the mint and tea tree – it feels invigorating, like a mini scalp massage in a bottle. Despite being sulfate-free, it lathers well and cleanses without making my hair feel like straw. In fact, my hair felt soft but voluminous. Over a few weeks, I saw less hair fall in the shower. One 77-year-old reviewer even said their hair was “thicker and shinier” after just three uses instyle.com, which is remarkable (individual results vary, of course, but it shows how quickly healthier hair can appear). This shampoo is great for both women and men. The scent is herbal (rosemary-mint) and quite pleasant. Honestly, considering the price and ingredients, it offers the best bang for your buck. The only con I can think of is that because it’s so popular, it sometimes sells out – and of course, like all hair products, you need to stick with it to see sustained results. But overall, it’s my top budget-friendly pick to strengthen thinning hair.

Buy on Amazon

Features:

Rosemary Oil – stimulates follicles (natural growth aid)
Biotin – supports keratin for stronger strands
Tea Tree & Peppermint – cleanse scalp and reduce dryness
Sulfate-free and gentle formula
For men & women, all hair types

Pros:

Thickening effect – hair feels fuller over time
Cleans without stripping natural oils instyle.com (gentle on hair)
Soothes scalp (reduces itch and flakes)
Very affordable for the quality
Tons of positive reviews (proven track record)

Cons:

Contains natural essential oils – do a patch test if very sensitive
The minty tingle might be strong for some (I find it nice, though)
You’ll likely need a conditioner after (to detangle, since it focuses on cleansing and thickening)
As always, not a one-day miracle – needs continuous use

Best For: Budget-conscious folks with thinning hair. It’s especially great if you prefer natural ingredients like rosemary and want to see improvement in hair thickness and scalp health without spending a fortune.

7. Uttse Biotin Hair Growth Shampoo for Men (Tea Tree, Ginseng & Mint) : Best Shampoo for Hair Growth

Guys, if you’re very active or have an oily scalp along with thinning hair, the Uttse Biotin Hair Growth Shampoo might be your new best friend. It’s my pick for best men’s shampoo because it was literally made for men’s hair needs. The formula is loaded with botanicals like ginseng, tea tree oil, peppermint, and rosemary, plus biotin for strength. What’s unique is that they mention using it morning and evening – a nod to men who might shower twice (for example, after the gym). In the morning it fortifies follicles, and in the evening it helps detox the scalp from sweat and oil build-up amazon.com. As someone who works out often, I appreciate this concept – it really does leave your scalp feeling clean and refreshed after a sweaty session, without over-drying.

When I tried it, I loved the cool, minty sensation (tea tree and peppermint are great for that “deep clean” feel). My scalp felt invigorated and any itchiness calmed down. The argan oil in it kept my hair from feeling stripped (it’s in the ingredients to add moisture). After a couple of weeks, I noticed less dandruff and my hair looked a bit thicker at the roots. This shampoo has a solid 4.3/5 rating with over 1,200 reviews amazon.com, and it’s even an Amazon’s Choice with thousands of buys per month – pretty reassuring. Another plus: it’s from a small business brand, which I like to support.

Keep in mind, it’s labeled “unscented” but that just means no artificial fragrance; it actually has a natural herbal/mint smell from the ingredients (which smells clean). Also, it’s primarily marketed to men – nothing prevents women from using it, but the focus is on issues like receding hairlines, oily scalp, etc., common for gents. On the downside, if you only wash 2-3 times a week, you might not reap the full “twice-daily” concept benefits – but that’s not a dealbreaker. And while it helps reduce shedding and flakes, like others it won’t regrow hair on a bald spot overnight. Still, for maintaining healthy scalp and thicker-looking hair, it’s a winner.

Buy on Amazon

Features:

Biotin-infused thickening formula
Tea Tree Oil, Peppermint & Rosemary – scalp stimulation & cleansing
Ginseng extract – improves circulation to roots
Argan oil – adds moisture and shine

Pros:

Cleanses oily scalp effectively (great post-workout)
Reduces dry, itchy scalp and dandruff amazon.com
Hair feels stronger and looks fuller with use
Refreshing cooling effect (invigorating wash)
Good value (around ~$20 and long-lasting bottle)

Cons:

Marketed towards men (branding might not appeal to women)
If used twice a day, you’ll go through it faster
Peppermint/tea tree tingle is strong – not for those who dislike that sensation
Results for hair growth are subtle – mainly prevents breakage and maintains thickness
You’ll still need patience for significant changes

Best For: Men with thinning hair or early hair loss, especially if you have an active lifestyle or oily scalp. It’s ideal for keeping your scalp clean, dandruff-free, and primed for healthy hair growth (while giving a bit of thickness boost to existing hair).

FAQ: Best Shampoos for Hair Growth

Q: Do hair growth shampoos really work?
A: They help support healthier, fuller hair, but keep expectations realistic. Hair growth shampoos work mainly by strengthening existing hair, reducing breakage, and improving scalp conditions (like clearing buildup or balancing oils). This creates an optimal environment for hair to grow. Many contain ingredients known to aid hair health (biotin, caffeine, rosemary, etc.), which can reduce excessive shedding health.com and make hair appear thicker. However, they won’t instantly sprout new hair from bald spots. Consistent use over weeks or months is usually needed to see results. Think of them as one part of a hair care routine – they work best alongside a healthy diet, possibly supplements, and good hair habits.

Q: What’s the best shampoo for hair growth and thickness?
A: It depends on your needs, but a great all-around choice is the Biotin & Rosemary Shampoo (Best Overall pick) in this list. It’s sulfate-free, packed with biotin and natural growth stimulators, and suitable for most people. It helps thicken strands and reduce thinning. If you’re specifically looking to boost thickness, the Svvimer Rosemary Shampoo is another excellent option – it’s enriched with rosemary oil and biotin and has rave reviews about improving hair density. For maximum thickness, you could also use a matching conditioner (for example, the Shapiro MD set) to further plump the hair shaft. Remember, “thickness” can come from reducing breakage (so your hair can grow longer and fuller) and swelling the hair shaft a bit – the shampoos above tackle both of those angles.

Q: Which shampoo is best for men’s hair growth?
A: Men often benefit from shampoos that address DHT and scalp buildup. Shapiro MD Shampoo is a top pick for men because it’s formulated by dermatologists to fight DHT – a big cause of male hair loss. It’s effective for many guys experiencing early thinning. On the more natural side, the Uttse Biotin Hair Growth Shampoo for Men is great for everyday use – it keeps the scalp very clean (tea tree + peppermint) and nourishes follicles with biotin and ginseng. Men’s scalps can be oilier, so something like Uttse or the Spartan Root Activator (with ginger and licorice) helps balance oils and keep the environment healthy for hair. All these will help maintain thickness and reduce excessive shedding. For severe hair loss, men might need to pair shampoo with treatments like minoxidil or finasteride, but as far as shampoos go, those are top-notch for daily care.

Q: What about women’s hair – what’s the best shampoo for hair growth for women?
A: Most of the shampoos in our list are unisex, but for women specifically, a gentle formula that nourishes the scalp is key. Svvimer Rice Water Shampoo is wonderful for women, as it’s gentle, hydrating, and helps with overall hair quality (women often deal with dryness or breakage in addition to thinning). Also, Nativo’s Hair Growth Shampoo is great for women with fine hair – it’s full of vitamins and botanicals to strengthen strands (women can experience a lot of shedding from stress or post-pregnancy, and a strengthening shampoo can help). If hormonal changes (like postpartum or menopause) are a factor, Shapiro MD is also effective for women because it targets those hormonal DHT effects. In short, women should look for a shampoo that balances the scalp (not too harsh), adds volume, and contains ingredients like biotin, rosemary, or even mild DHT blockers to tackle thinning from multiple angles.

Q: How long does it take to see results with hair growth shampoos?
A: Patience is key. Generally, you might notice improvements in hair texture and reduced shedding within 2–4 weeks. For visible changes in thickness or new growth, expect around 8–12 weeks of consistent use. This is because hair follicles take time to cycle and show new growth. For example, in some studies rosemary oil took six months to show comparable results to standard treatments instyle.com. Don’t be discouraged if you don’t see drastic changes in a few days. Give the shampoo at least a couple of months. Meanwhile, you can track progress by taking before-and-after photos of your hair part or hairline. Also, remember to massage the shampoo into your scalp for a good 1-2 minutes – this helps increase blood flow to the roots and ensures those active ingredients really penetrate.

Q: Can these shampoos regrow hair on bald spots?
A: It’s unlikely to regrow hair on completely bald areas (especially if follicles have been inactive for a long time). Shampoos are most effective for thinning areas and overall hair quality. They work by strengthening existing follicles and preventing further loss. If you have a new thinning spot (say, in the last year or so), a good shampoo might help thicken the hairs there and slow down the loss. But if it’s a shiny bald patch, you’d likely need medical treatments (like minoxidil, laser therapy, or a hair transplant) to see regrowth. Think of these shampoos as preventative and supportive care – they help keep the hair you have for longer and make it appear fuller. Many people use them in conjunction with other treatments for a combined effect.

Keep in mind: healthy hair growth also comes from within. Along with a good shampoo, make sure you’re eating a balanced diet (protein, vitamins like Biotin and Vitamin D, iron, etc. are important for hair). Stay consistent with whatever product you choose – and be gentle to your hair (avoid super tight hairstyles, harsh chemicals, or heat tools that damage hair). Here’s to stronger, thicker hair ahead!
