Disinfect the derma roller with medical alcohol before and after each use. Lightly wet and comb hair before use to prevent tangles. For longer hair, part hair in sections and using gentle pressure, roll the derma roller back and forth 5-10 times horizontally, vertically and diagonally. Temporary redness and minor discomfort may occur. Then pump Hairy Man Care's Hair Growth Serum at the roots on wet or dry hair and massage in or leave to dry.

Warnings: Use Hair Growth Derma Roller once a day and no more than 2 times a week – do not use again until treated area has fully healed. 

Hairy Man Care's Hair Growth Serum can be used daily.
