The 7 Best Shampoos for Hair Growth of 2024

Whether you’re growing out your hair or want to revitalize strands after experiencing hair loss, taking care of the hair and the scalp can help you achieve your goals. Just like our complexions, a healthy scalp and strands all start with cleanliness, and shampoos specifically formulated for hair growth are where the magic happens. 

“While other factors may come into play like medications, treatments, diet, and health conditions, the way that you take care of your hair is key to its growth and health,” Dr. Dendy Engleman, a board-certified cosmetic dermatologist and Mohs surgeon at Shafer Clinic in NYC, tells PEOPLE. She explains that healthy hair is closely linked to a healthy scalp, hair care techniques, and hair products, which is why if you want longer, fuller strands, utilizing a shampoo for hair growth can help up the ante on your efforts. “Hair growth shampoos contain ingredients that are designed to support and stimulate hair growth, which can make a considerable difference in the rate of hair growth,” Dr. Engelman notes. 

Since hair growth is a popular goal, there are plenty — and we mean plenty — of hair growth shampoos available at our favorite beauty shopping destinations. So, how do you know which ones work best and will actually give you your desired results? The answer lies in trial and error, which is exactly what we did: Our PEOPLE Tested team researched and washed their hair with nearly two dozen formulas, carefully considering the ingredients, efficacy, and results to determine which hair growth shampoo formulas are worth buying. After much deliberation, we narrowed it down to the top seven shampoos for hair growth.

Best Overall

Vegamour GRO+ Advanced Replenishing Shampoo

Vegamour

Pros
  • With regular use, this shampoo was nourishing enough to restore our tester's natural wave pattern. 

  • Our tester's hair grew about 1.5 inches during the testing period and their baby hairs appeared thicker. 

  • The formula worked well at providing a deep yet hydrating cleanse.

After six weeks of testing, we were blown away by our results with the Vegamour GRO+ Advanced Replenishing Shampoo. This formula is specifically designed to enhance hair growth and features numerous ingredients to help support scalp health and invigorate follicles, including Karmatin™, which is a vegan keratin alternative that effectively supports strand strength and can help fill in damaged areas. Additionally, this hair growth shampoo contains cannabidiol (a.k.a. CBD) to support scalp health, boost the growth cycle, and pause the hair loss effects of DHT, a testosterone-based hormone that can shrink hair follicles at high levels.

Throughout the testing period, we were impressed by how well this formula cleansed the scalp and how quickly we saw re-growth. After just a few weeks, our tester noticed some improvement and, once the six weeks were complete, they measured around 1.5 inches of hair growth. We found that while this formula works best for boosting hair growth, it’s most effective on those with thinning or fine hair as well as those who experience dry, flaky scalps as the CBD can help soothe the side effects of this common scalp woe. 

Size: 8 ounces | Key Ingredients: Cannabidiol, Karmatin™ | Hair Type: All, especially those with dry, flaky scalps

Amazon

Our Ratings

Pros
  • It improved the overall health of our hair while also boosting hair growth.

  • Our tester's baby hairs grew by up to 1 inch. 

  • The formula feels super gentle on the scalp and provides lasting nourishment.

Cons
  • None that we could find.

If you’re looking for the best shampoo for hair growth and want something a little (okay, a lot) more budget-friendly, we found that the Marc Anthony Grow Long Super Fast Strength Shampoo is worth trying. This drugstore formula — which you can score for under $10 on Amazon — is enriched with hair growth-supporting ingredients including caffeine, ginseng, and vitamin E. And, despite its cheaper price tag, it works really well at supporting hair growth. 

Our tester typically experiences a healthy amount of hair growth from month to month, however, they noted that their hair has never looked or felt as healthy as when using this shampoo and that it was especially "soft and silky." Additionally, they noticed that their baby hairs saw a major improvement with one inch of re-growth at the end of the testing period. 

Size: 8.4 ounces | Key Ingredients: Caffeine, ginseng, vitamin E | Hair Type: All, especially those prone to breakage
