KOI Derma Roller (0.5-1.0mm)
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.
1. Wet your hair before using the derma roller on your scalp. This will help prevent your hair from getting tangled in the roller.
2. Begin using the derma roller at the front of the scalp on or near the hairline and work your way down the back of the head (treating only the areas where hair loss has occurred).
3. Focussing on one section of the scalp at a time, roll each area 10-15 times. You can do this by rolling horizontally, vertically and diagonally, three or four times each way, like this:
Roll in one direction only when the needles are in contact with the scalp (don’t go backwards and forwards) and try to roll from the hair roots to the ends. This will prevent any hair getting caught in the needles.
5. Repeat this process until you have covered all areas needing the treatment.
6. Apply minoxidil to the treated area and massage gently into the scalp
You only need to apply a moderate amount of pressure. Rolling too aggressively won’t give you better results and can cause skin irritation, scratches and/or needle marks.
