Micro needling, also known as collagen induction therapy, is a minimally invasive cosmetic procedure that involves the use of fine needles to create tiny punctures in the skin. This process stimulates the body's natural healing response, leading to the production of collagen and elastin, which are essential proteins for maintaining skin health and elasticity.
When applied to the scalp, micro needling has been shown to promote hair growth by increasing blood flow to the hair follicles and stimulating the production of growth factors. It can be particularly beneficial for people with hair loss conditions such as androgenetic alopecia (male-pattern baldness) and alopecia areata (patchy hair loss).
