The Science
Microneedling or Dermaroller is a cosmetic process of pricking the scalp with special needles. This is an excellent scientific hack to make your body produce more elastin and collagen (naturally) to trigger hair growth or make your skin younger.
Dermal papilla and stem cells are stimulated when collagen induction treatment causes micro-injuries to the skin. The increased blood supply to the hair follicles from microneedling also stimulates new hair growth.
Even when the hair follicle is smaller, progenitor cells aid in the formation of hair. Skin-rolling micro-needling boosts stem cell synthesis, which in turn boosts the creation of progenitor cells.
Microneedling may help the absorption of other hair loss treatment products like topical steroids and Rogaine.
Microneedling was found to reduce the appearance of fine lines, wrinkles, and pore size, as well as enhance the overall appearance of the skin in studies conducted between 2010 and 2015.
Dermarolling and microneedling’s primary advantage is the enhanced production of collagen. Collagen helps to reduce the appearance of wrinkles and decreases in amounts gradually as people age.
