Micro Needling

Micro Needling, also known as derma rolling, involves using a roller with tiny needles ranging from 1 mm to a few mm in length rolled over the affected scalp area, creating small wounds in the scalp. These wounds are thought to stimulate the release of essential growth factors, improve blood supply through neovascularization, and induce collagen formation. The combination of these effects is believed to stimulate the growth of hair follicles and thicken the hair shafts. The scalp is thick, and using a micro needling device may improve the penetration of topical hair loss treatments such as minoxidil or topical steroids used to treat alopecia areata. Micro Needling may cause bruising, swelling, pain, redness, infection, and scarring. No large-scale studies have been conducted that prove using micro Needling alone is an effective therapy for hair loss. Most of the published studies have been done in combination with topical hair loss treatments. Many hair loss excerpts believe that micro Needling leads to increased scar tissue formation in the scalp, which in turn can contribute to hair loss.
