Glycolic Acid Is a Top-Notch Ingredient for Healthy, Lustrous, Glass-Like Hair—Here’s the Reason.

      In the realm of skincare, glycolic acid is a standout ingredient. This exfoliating acid is celebrated for its ability to diminish discoloration, refine texture, unclog pores, and enhance collagen production. Recently, however, it has begun appearing as a key component in popular hair care products. I must admit, this caught my attention. How could such an exfoliating acid possibly be beneficial for my hair? After encountering a new hair care product featuring glycolic acid on my Instagram feed, I thought it was time to consult an expert—specifically, Rick Wellman, Master Celebrity Colorist and Hairstylist at The Salon Project in NYC.

      I won't spoil the details, but after discussing my questions with him, I am now convinced that everyone should consider incorporating glycolic acid into their hair care routine. This trend underscores that the "skinification" of the scalp and hair is still thriving, and there are actual advantages to integrating skincare-grade ingredients and methods into haircare. Below, you'll discover everything you need to understand about how this ingredient, once limited to skincare, can significantly enhance your scalp and hair health.

      As previously mentioned, glycolic acid is an exfoliating acid, and it’s crucial to recognize that there are two types of exfoliating acids: alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs). "Glycolic acid is an AHA derived from sugarcane," explained dermatologist Ife Rodney, MD, FAAD, of Eternal Dermatology and Aesthetics, in an earlier conversation with Who What Wear. "It’s a widely used active ingredient in skincare due to its exfoliating properties."

      So, how does it help hair? "There are some unusual methods circulating on TikTok for using glycolic acid in scalp and hair treatments," Wellman notes. "Clients at our salon often ask, 'Is this for real and does it actually work?' My quick answer: Yes, it's both authentic and trending." According to Wellman, glycolic acid works by loosening dead skin and enhancing moisture and elasticity, making it a fantastic addition to products aimed at exfoliating the scalp and eliminating buildup. Whether contained in a purely chemical exfoliant or paired with a physical exfoliant (like in a salt scrub), it can effectively remove product accumulation while restoring balance to the scalp and hair.

      Beyond exfoliation, glycolic acid can improve moisture levels in the scalp and hair and even increase shine by reinforcing hair strands and smoothing the cuticle, resulting in a glossy finish. "Glycolic acid can address oily scalps or flaking issues while providing that desirable combination of balanced moisture and strength," Wellman explains. "Think of it as a 'scalp facial' when it’s applied correctly, especially in conjunction with a certified 'head spa' setup." With the rising demand from clients, Wellman has recently updated his entire shampoo area to include reclining chairs and waterfall rinsing sinks for a spa-like feel—it’s further evidence that we are in an era focusing on the "skinification" of scalp and hair. Consumers are eager to enhance their hair routines with facial-grade ingredients, treatments, and experiences—glycolic acid meets this need.

      When it comes to using glycolic acid for scalp and hair, there are now numerous products available, making it easy to adhere to the best usage instructions on the label. However, Wellman shares a couple of essential points. First, do not apply a glycolic acid exfoliating treatment to the scalp or hair more than once a month (max twice). "Here’s a reality check based on experience: Using high-grade glycolic toners on a weekly basis is risky. Overuse can weaken hair over time and cause damage to the scalp barrier. Glycolic acid is not a treatment for hair growth."

      Second, steer clear of high-strength glycolic acid treatments on sensitive scalps or immediately following a hair coloring procedure, as "I've observed it can strip some color molecules," he notes. However, if used appropriately, he asserts that glycolic acid can genuinely benefit the scalp and hair. "There are effective ways to utilize glycolic acid for incredible results. So, I advise researching beyond just following TikTok trends, especially when it comes to chemicals and your skin and scalp." Below, you can find a selection of the top glycolic acid products.

      "I suggest starting with a low-impact approach to glycolic acid treatments for the scalp and hair, such as Davines Naturaltech Detoxifying Scrub Shampoo paired with Davines Renewal Serum Superactive," Wellman advises. "These products don't rely solely on glycolic acid. Begin there, then assess how your hair and scalp respond."
