Derma rollers work in two ways – in addition to prompting the scalp to produce more collagen and thus supporting the growth stage inside the hair follicle, it also improves blood flow. The epidermis reacts to the wound by sending more blood to the wound to heal it. Not Completely necessary but apply Hair Growth Serum to the affected areas and roll your roller four or five times over the scalp in different directions and leave to heal. If irritation occurs stop use immediately.
How to use
Take your derma roller and gently roll it over your skin vertically, horizontally, and diagonally, rolling twice over your cheeks, forehead, chin, lips, and neck. No need to press too hard or put yourself in pain—apply as much pressure as you can comfortably tolerate.
