I got my 1.0 roller but I’m afraid. I read that people have been told that rolling once a week for years on the temples can damage the skin, and hair cant be transplanted there. I want to be able to have a transplant to my hairline in the future. Any way that’s not true?
There is good evidence that dermrolling wounding induces some hair growth in some men. This appears to be enhanced when minoxidil is used. A depth of at least 1 mm will get below the epdermis and into the dermis. The stem cells are found at about 1-2 mm below the epidermis. A hair transplant goes down much deeper and takes with it the stem cells along the entire hair shaft as well as the very important stem cells at the bottom of the hair shaft (the bulb of the hair follicle) and this goes down to a depth of between 5-7 mm so dermarolling should not impact a hair transplant
