0.25 mm GRO Advanced Scalp Dermaroller

A dermatologist-codeveloped dermaroller that gently exfoliates the scalp, preparing it for a hair serum (sold separately) and improving the serum's efficacy. The gentle 0.25 mm stainless-steel needles are the same length used in most professional settings, the wide head offers maximum coverage, and the head can be replaced monthly (refill sold separately). In a 150-day clinical study of 40 participants using the dermaroller together with the matching hair serum, 91% saw a reduction in visible signs of thinning, 91% saw less visible scalp and 96% saw thicker-, fuller-looking hair (results are from the combined use, not the dermaroller alone). Vegan. Hair Texture: Straight, Wavy, Curly and Coily. Hair Type: Fine, Medium and Thick. Hair Concerns: Thinning, Flaky and Dry Scalp.

How to use: Sanitize before use with an alcohol-based sanitizer. Hold wet or dry hair down tightly against the scalp and, using gentle, even pressure, roll five times horizontally and five times vertically across the scalp. Sanitize after use, allow the dermaroller to dry, and replace the head monthly.
