Beauty Hair Hair & Scalp Care FYI: Snail Mucin Shampoo Exists, and Shoppers Say It “Regrows Hair Lines” Others say it helps with “thickness.” By Tamim Alnuweiri Tamim Alnuweiri Tamim is beauty commerce writer at InStyle, with nearly a decade of experience writing about beauty, fashion, wellness, and music. InStyle's editorial guidelines Published on August 7, 2024 @ 03:00AM Photo: Zain Is there a buzzier skin care ingredient than snail mucin? When I first covered it in 2014, it was niche and new; the idea grossed a lot of people out. A decade later and it’s the exact opposite—snail mucin is in some of the most eternally popular products. As I learned recently, it’s not just making an appearance in skin care, it’s in hair care products, too, like Zain1’s Natural Hair Growth Formula Shampoo. I came across Zain1’s shampoo while scrolling through Amazon looking for more snail mucin skin care products to satiate the world’s seemingly endless appetite. It’s the first shampoo, conditioner, and hair serum formulated with the buzzy K-beauty ingredient I’ve ever seen. While that’s impressive enough, it also has purported growth benefits corroborated by shopper reviews. Natural Hair Growth Formula Shampoo Amazon $28 $22 at Amazon This formula reads like the back of a skin care serum bottle; there’s snail mucin, caffeine, azelaic acid, niacinamide, and rosemary. While each of these ingredients has their own full list of benefits, I’ll give you the TL;DR: save for snail mucin itself (which needs more research concerning hair), everything else scientifically backs up the brand’s claim that the shampoo helps with hair growth, heals damaged strands, strengthens hair, improves scalp health, and increases volume. Zain1’s Natural Hair Growth Formula Shampoo seems to be a relatively new product—the earliest review is from August 2023. Still, the ratings are trickling in and the majority of them are five-star. One shopper who was “losing [their] hair due to stress,” said that after two months they saw “regrowth on [their] hairline” plus “increased thickness.” Another person who “lost almost all [their] hair,” said their strands grew back so much that they “stopped wearing hair extensions.” Zain1’s Natural Hair Growth line is simply the latest frontier for snail mucin beauty-world domination, it likely won’t be the last. Head to Amazon to shop its Natural Hair Growth Formula Shampoo, the corresponding conditioner, hair serum, or a discounted set containing all three products.
