Glycolic Acid is a premier ingredient for achieving strong, shiny, glass-like hair—here’s the reason why.

      In the skincare realm, glycolic acid stands out as a key component. This exfoliating acid is well-known for its effectiveness in reducing discoloration, refining texture, unclogging pores, and enhancing collagen production. Recently, however, it has emerged as a prominent ingredient in many hair care products. This trend made me curious: how could this exfoliating acid provide benefits for hair? After spotting a new glycolic acid-infused haircare product on my Instagram feed, I realized it was time to consult an expert—Rick Wellman, Master Celebrity Colorist and Hairstylist at The Salon Project in NYC.

      I don't want to give everything away, but after posing my pressing questions to him, I'm convinced that everyone should consider adding glycolic acid to their hair regimen. It’s evident that the trend of applying skincare principles to scalp and hair health continues to thrive, and there are genuine advantages to integrating facial-grade ingredients and techniques into hair care. Read on to discover how this ingredient, originally intended for skin, can significantly enhance your scalp and hair health.

      As we've established, glycolic acid is an exfoliant, but it's crucial to understand that exfoliating acids fall into two categories: alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs). "Glycolic acid, derived from sugarcane, is an AHA," explains Dr. Ife Rodney, a dermatologist at Eternal Dermatology and Aesthetics. "It is a widely used active ingredient in skincare for its exfoliating properties."

      So, how does it help hair? "We're observing some unconventional uses for glycolic acid in scalp and hair treatments on TikTok these days," Wellman notes. "Our salon clients are questioning its legitimacy and effectiveness. My brief answer: it’s both genuine and in vogue." He explains that glycolic acid loosens dead skin and enhances moisture and elasticity, making it an excellent addition to scalp-exfoliating and product-buildup-removing products. Whether used in a purely chemical exfoliant or combined with a physical exfoliant (like in a salt scrub), it helps eliminate buildup and restore balance to the scalp and hair.

      Beyond exfoliation, glycolic acid hydrates the scalp and hair, potentially increasing shine by fortifying hair strands and smoothing the cuticle for a reflective finish. "[Glycolic acid] addresses oily scalp or flaking while providing that ideal blend of moisture and strength we all appreciate," Wellman states. "When used correctly, it's akin to a 'scalp facial,' especially when paired with a certified 'head spa' setup." To cater to client demand, Wellman recently transformed his shampoo area with reclining flat-bed chairs and waterfall sink rinses for a spa-like feel, reinforcing the trend toward "skinification" in scalp and hair care. Consumers seek to elevate their hair routines with face-grade ingredients, treatments, and experiences—glycolic acid fits this need perfectly.

      How to incorporate glycolic acid into scalp and hair care? With numerous glycolic acid-infused products available, following the usage instructions on the label is straightforward. Nevertheless, Wellman has some key advice. First, limit the use of glycolic acid treatments on the scalp or hair to once a month (or twice, at most). "Here's a reality check from my experience: using face-grade glycolic toners weekly is not advisable. If misused, it can weaken hair over time and damage the scalp barrier. Glycolic acid is not a hair growth solution."

      Second, avoid applying high-strength glycolic acid treatments on sensitive scalps or immediately after hair coloring. "I've seen it remove some color molecules," he cautions. That said, if used safely, glycolic acid can provide significant benefits to the hair and scalp. "There are indeed proper ways to utilize glycolic acid for remarkable results, so do your research and don't rely solely on TikTok hype, particularly when it concerns chemicals affecting your skin and scalp." Below, you'll find some of the best glycolic acid products.
