Whether you're trying to grow your hair longer or dealing with hair loss, the right hair growth products can make a difference. These products use nourishing formulas with powerful ingredients to revitalize strands, stimulate hair follicles, and create an optimal scalp environment for hair growth.
"Hair growth products improve hair density and reduce breakage, preventing hair from snapping at the ends," says Anabel Kingsley, brand president and consultant trichologist at Philip Kingsley.
With so many products claiming to boost hair growth, how do you know which ones work? Our PEOPLE Tested team rigorously researched and tested the top hair growth products.
Over six weeks, we evaluated 129 products, including hair growth oils, serums, shampoos, conditioners, and scalp massagers. After 624 hours of testing oils and serums and 414 hours of testing shampoos, we're ready to share our top picks.
Here are the best hair growth products on the market, proven to support and stimulate new hair growth.
Best Hair Growth Oil
Mielle Organics Scalp & Hair Strengthening Oil
Pros
After six weeks of testing, our hair felt thicker, and we noticed new growth around our hairline. The gentle formula doesn’t have a tingling sensation or cause irritation, even on sensitive scalps. The formula spreads easily across the scalp, so a little goes a long way.
Cons
Since it’s an oil, it’s not as compatible with oily scalps (especially if you want something you can apply during the daytime).
In our testing of 26 hair oils and serums, Mielle Organics Scalp and Hair Strengthening Oil stood out as the best for hair growth. With rosemary, mint, and biotin, it deeply nourishes the scalp, promoting healthier hair. Priced around $10, it's a steal for its effectiveness. The gentle formula, with a cooling effect from mint and rosemary, is suitable for sensitive scalps. While best for nighttime use due to its oiliness, it yielded impressive results in just six weeks, with thicker roots and noticeable new growth.
Size: 4 oz. | Key Ingredients: Rosemary, mint, biotin
Best Hair Growth Oil, Runner Up
Vegamour Gro Hair Serum
Pros
The application process is beginner-friendly and mess-free.This oil formula absorbs into the scalp in less than one minute without residue or weighing roots down. At the end of the six-week testing period, we saw some new growth, especially around our hairline.
Cons
Compared to the Mielle Organics Scalp & Hair Strengthening Oil, it’s a bit of an investment. This formula helps thicken hair with new growth vs. improving overall length.
Mielle Organics Scalp & Hair Strengthening Oil is our top pick, but we also recommend Vegamour Gro Hair Serum. With turmeric, red clover, and mung bean, it protects the scalp and strengthens strands. It's lightweight and absorbs quickly, ideal for oily hair. While not focused on length, it reduces shedding and promotes new growth, leaving roots thicker by the end of testing.
Size: 1 oz. | Key Ingredients: Curcumin stem cell extract, red clover, mung bean
Best Hair Thickening Oil
Wild Growth Hair Oil
Pros
The formula has an intuitive application process that is mess-free and makes it easy to target specific areas of the scalp.Throughout the testing period, our hair grew in length and thickness .In addition to promoting hair growth, this formula improved our hair’s hydration levels.
Cons
The formula includes some heavier oils including olive and coconut oil that might weigh down thin hair types or interfere with oily scalps.
For a budget-friendly option that effectively boosts hair length and thickness, try Wild Growth Hair Oil. Its blend of olive, jojoba, and coconut oils absorbs well into the scalp and hair, promoting hydration and growth. Ideal for thick hair and dry scalps, though those with fine hair may notice some residue.
Size: 4 oz. | Key Ingredients: Olive oil, jojoba oil, coconut oil
Best Hair Growth Shampoo, But for Less
Marc Anthony Grow Long Shampoo
Pros
The formula costs under $10 a pop. In addition to promoting hair growth, the formula also targets split ends and helps restore damage. When using this formula, our hair felt shinier and smoother. Our hair grew around 1.5 inches during the 6-week testing period.
Cons
It’s not as effective at promoting new growth compared to other products on this list.
The Marc Anthony Grow Long Shampoo, infused with caffeine, ginseng, and vitamin E, energizes the scalp, stimulates hair growth, and fortifies against further loss—all for less than $10 a bottle. Our six-week trial yielded an impressive 1.5 inches of growth, exceeding expectations.
But it's not just about length; this formula also nourishes, strengthens, and protects hair, particularly targeting damage and split ends. It leaves hair smoother, shinier, and healthier overall.
Size: 8.4 oz. | Key Ingredients: Caffeine, ginseng, vitamin E
Best Hair Growth Conditioner
Redken Extreme Length Conditioner
Pros
The formula is thick and creamy but not too heavy, so you don’t have to worry about it weighing down strands or leaving behind a greasy residue. After the six-week testing period, our hair looked longer and healthier than before. We saw improvements to our hair length in just three weeks of use.
Cons
We loved everything about this hair growth conditioner.
After testing 25 hair growth masks and conditioners, Redken Extreme Length Conditioner emerged as the top choice. With amino acids and citric acid, it nourishes hair for long, strong growth without heaviness or residue. Just one dollop is enough even for longer hair, delivering noticeable results in as little as three weeks.
Size: 1 oz., 10.1 oz., 16.9 oz., 33.8 oz. | Key Ingredients: Amino acids, arginine, citric acid
Best Hair Growth Conditioner, Runner-Up
Nutrafol Strand Defender Lightweight Strengthening Conditioner for Thinning Hair
Pros
Throughout the testing period, we noticed much less shedding and improved hair growth around our hairlines. It naturally detangles hair and, therefore, can help prevent further damage and breakage.
Cons
The formula is designed to reduce thinning.
For thinning hair, try Nutrafol Strand Defender Lightweight Strengthening Conditioner. Enriched with ximenia oil and vegan proteins, it strengthens strands, improves moisture, and promotes new growth. It reduces shedding and helps protect against damage, leaving hair healthier overall.
Size: 8.1 oz. | Key Ingredients: Ximenia oil, vegan proteins, glucose fibers
