While used as an anti-aging skin treatment, micro needling 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.
