Raechele Cochran Gathers, MD What is Microneedling?
Microneedling is a popular dermatology procedure that uses small pinpoint needles that are repetitively rolled or applied over the skin surface. The miniature needles cause many tiny injuries within the skin, but minimal damage to the epidermis (skin surface) itself. These small injuries caused by microneedling lead to a ‘wound healing chain reaction” that forms new collagen, new blood vessels and stimulates the release of growth factors into the treated area.
The healing chain reaction effect caused by microneedling is thought to heal and rejuvenate the skin, and to help improve hair growth. The microneedling technique also aids in the absorption of medications that are placed on the treated skin or scalp.
Microneedling for Hair Loss
Microneedling is a popular treatment for hair loss, and has been used for male and female pattern hair loss. It has also been used to treat other forms of hair loss, including traction alopecia. Many of the studies on microneedling and hair loss have focused on androgenetic alopecia. There are also some studies showing the successful treatment of alopecia areata with microneedling. Other studies have shown impressive results regrowing hair using a combination of microneedling and minoxidil or PRP, which are both popular treatments for hair loss.

What is a Derma Roller?
A derma roller is a popular microneedling device. It is an instrument that is covered in tiny needles, usually measuring between 0.5mm to 1.5mm that are repetitively rolled over the skin. The needles cause tiny injuries to the skin, and these minute injuries cause a wound healing and skin regeneration cascade which is thought to help improve scars, rejuvenate the skin and stimulate new hair growth.
Derma Rollers for Thin Edges
Traction alopecia occurs because of excessive pulling and tension on the hair and scalp. Most commonly, women with traction alopecia have thin edges—or even baldness—at the front hairline and temples. Tight ponytails, weaves, improper use of adhesive glues and aggressive braiding and hair-styling can all lead to traction alopecia. While there is limited data looking specifically at derma roller usage thin edges and traction alopecia, there are several studies supporting the use of derma roller for other forms of hair loss like female pattern thinning and alopecia areata.
