Home dermarollers and hair growth: trichologist weighs in

At-home dermarollers have become widespread as scalpcare trends grow on TikTok, and trichologist Kevin Moore says microneedling can stimulate scalp collagen, may encourage follicle stem cell activity, and can improve topical product absorption.

Home microneedling devices, often called dermarollers, have become part of a growing scalpcare trend. The #scalpcare hashtag on TikTok has amassed over 1 billion views. Microneedling was once mainly a clinic treatment, but at-home rollers are now widely available online and are relatively inexpensive. Trichologist Kevin Moore is quoted saying dermarolling was developed for acne scarring and can stimulate collagen in the skin. He also reported that research shows scalp rolling can encourage stem cell activity in hair follicles and improve absorption of topical hair treatments. Key facts: - The #scalpcare hashtag on TikTok has more than 1 billion views, indicating large consumer interest. - Home dermarollers use many small needles to create tiny punctures in the surface layers of the scalp. - The article reports that at-home microneedling tools are increasingly available online and are more affordable than clinic procedures. - Kevin Moore, a trichologist at Regrowz, explains dermarolling can stimulate collagen, may encourage stem cell activity in follicles, and can promote absorption of hair products. - The article mentions a commercial product whose brand claims it can enhance hair density by up to 50%. Summary: The rising interest in scalpcare has made at-home microneedling more common and prompted discussion about its possible effects on scalp health and hair. A trichologist described mechanisms such as collagen stimulation and potential follicle stem cell activation. Undetermined at this time.
