Shoppers with Thinning Hair Swear This Rosemary Growth Shampoo Leaves Their Strands ‘Fuller and Healthier’

As a Texas native, I know a thing or two about big hair. While I used to pride myself on my voluminous mane, it seems to be shedding more and more with each passing year. Whether it’s stress or age-related, I’m eager to get back to my roots. Enter: Nécessaire Rosemary Shampoo. 

This strengthening shampoo from Nécessaire is designed to promote hair health and regrowth, thanks to the high concentration of rosemary. It’s non-drying, lightweight, and has a soothing rosemary, jasmine, and cedar fragrance, making it not just effective, but luxurious to use. And thanks to its 20-percent-off discount on site, I’ll definitely be stocking up ahead of Black Friday. (Not to mention, Nécessaire is offering 20 percent off all orders and 25 percent off all orders over $100 on its site.)

“Rosemary shampoo can be beneficial to condition and strengthen hair and can also work to reduce hair damage and breakage, making the hair appear stronger,” Marisa Garshick, MD, FAAD, a board-certified dermatologist at MDCS Dermatology in New York City, previously told Shape.

But rosemary’s benefits don’t stop at strengthening the hair — they can actually lead to hair regrowth. While the exact mechanism is not quite clear, dermatologist and founder of Metropolis Dermatology James Y. Wang, MD, previously told Shape, “rosemary oil can help promote hair growth in some individuals with age-related hair loss.” 

Along with rosemary, the shampoo contains plant proteins, ceramides, and a microdose of the anti-thinning peptide complex, Capixyl. Plus, it’s safe for all hair types and textures. But don’t just take my word for it — here’s what real reviewers are saying. 

“Love the shampoo. Works great on my hair, makes it feel fuller and definitely healthier,” one five-star reviewer wrote. Another said, “I’ve been trying to find something to revive my postpartum hair, and this seems to do the trick.” 

But thick hair isn’t the only benefit of the shampoo. Other reviewers praise the product for its hydrating and softening effects, like this one: “My hair felt softer, stronger, and noticeably less frizzy from the very first use,” they wrote. Another said, “As a 49-year-old woman, I really appreciate the multi benefits of this line.”
