Microneedling is a type of cosmetic treatment that addresses various effects of aging. It’s also nicknamed skin needling because of its effects on increasing collagen production in the skin.
Microneedling involves the use of a skin roller with small needles that causes minor skin injuries.
While used as an anti-aging skin treatment, microneedling may also be a method of treatment for hair loss. There’s even evidence that it can help a special type of hair loss known as alopecia areata.
The same process of creating wounds in the skin is also thought to regenerate the health of the hair follicles. It’s thought that this can result in new hair growth, or perhaps, it may thicken thinning hair as seen in androgenic alopecia or male pattern baldness.
