Derma roller has since gained notoriety for fighting back against hair loss and helping stimulate new growth on the scalp. In clinical studies, when a derma roller was paired with minoxidil on the scalp, you will get excellent results. Essentially, the derma roller gently pricks the layers of skin to open the pores for maximum absorption of minoxidil. You can also use this on the scalp before using a Ketoconazole shampoo and any other hair loss treatments in your grooming regimen. After extensive use, users have shown dramatic results in scalp health and hair growth.
A derma roller is a handheld device with a wheel attached to a handle. The wheel is outfitted with tiny needles, just a few millimeters long. The device is rolled over the skin, causing the needles to press against the tissue. Originally, the derma roller was used to address skin imperfections, but a manufacturer has begun to market one model to the public as a treatment of androgenic alopecia. Hair growth relies on genes that promote the development of new hair cells. This takes place within the hair follicles, the small openings that cover the scalp as well as the rest of the body. A number of chemicals are needed to trigger the production of hair cells, and one of the most important of these is the human growth factor.
Scientists suggest that the derma roller works by triggering the production of human growth factor. When the needles are rolled along the skin, they cause minor surface wounds to the tissue. The body then must work to produce new skin in the area of the wound and releases the human growth hormone and other chemicals to assist with this process. Supporters of the derma roller believe that when these chemicals are released they also stimulate the growth of hair in the affected area, which can help begin regrowth in areas of thinning.
The idea behind the Derma Roller seems plausible; however, there is not enough clinical proof that the Derma Roller actually delivers on its promises. Unlike laser therapy, the Derma Roller is not an FDA-approved treatment for hair loss and has not been evaluated for safety or effectiveness. Some dermatologists and plastic surgeons even caution that the injury caused to the skin by needles may actually worsen hair loss in some people.
