The DS Laboratories Revita Shampoo is $35 at Amazon, where shoppers say they’ve seen new hair growth and less hair shedding. The formula contains caffeine and ginseng, which are scientifically proven to encourage hair growth.

Another said it reduced their hair fall by half.

Frankly, I was skeptical when I first heard about shampoos for hair growth. After all, the concept of skipping the hassle of a greasy scalp serum or style-flattening foam—yet reaping similar benefits simply by swapping your shampoo—sounded too good to be true. Shopper acclaim for the DS Laboratories Revita Shampoo, however, has convinced me that an in-shower treatment can, in fact, spur new growth.

The DS Laboratories Revita Shampoo is a strand-strengthening, follicle-stimulating hair and scalp cleanser. The formula stymies excess shedding, accelerates new growth, and delivers thicker hair within 90 days, per the brand. Specifically, the drug-free formula works via science-backed ingredients. 

For instance, the shampoo contains caffeine—an ingredient that, when applied topically, spurs nutrient-rich blood flow to the scalp and hair follicles, in turn, encouraging growth. Interestingly, one study found a caffeine-based solution to be equally as effective as minoxidil—the active ingredient in Rogaine—making it a solution to certain types of hair loss.

The DS Laboratories Revita Shampoo also features ginseng. Often found in cell-energizing skin care, the root functions similarly in hair care: Studies suggest ginseng proliferates dermal papilla—precursors to new hair growth that lie below the follicle. Plus, like caffeine, ginseng improves blood flow to support faster, healthier growth. 

Finally, the formula contains wheat protein, which fortifies feeble strands. Specifically, the ingredient repairs structural proteins within the hair shaft, which deteriorate from repeated heat damage and UV exposure. By repairing and strengthening strands, wheat protein prevents premature snapping and, ultimately, allows hair to reach new lengths.

Shoppers are impressed by their results. One reviewer who once struggled with hairfall reported “50 percent less” shedding thanks to the shampoo; plus, their hair felt “fuller” after only two uses. Another shopper, who had “lost all [their] hair” from illness said it’s “come back” with regular use of the formula. A final fan said the product has made their hair “thick and soft.”
