From Skin Microrelief to Wrinkles: An Area Ripe for Investigation

Microneedling at 0.6mm depth every two weeks showed better hair growth results than using minoxidil alone. Using a derma pen is recommended over a roller to avoid scarring.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

Use tretinoin three times a week, dermaroll once a week, and apply minoxidil daily, but avoid using all three on the same day. Tretinoin is preferred over hydrocortisone and should not be used immediately after dermarolling.

The conversation discusses using high molecular weight hyaluronic acid after microneedling to form a protective barrier, though it's considered expensive and offers marginal improvement. Users share experiences with different microneedling tools like derma rollers, dermastamps, and Dr. Pen, with some opting not to use any products on the scalp.

The user has been using minoxidil and finasteride for hair loss but is now considering microneedling due to recent hairline regression. Another user reassures that derma rolling causes only slight redness, which usually heals overnight.

Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.
