Also described as a dermaroller, microneedling with a micro roller is an innovative therapy that has a wide range of aesthetic applications and is becoming increasingly popular as a treatment to encourage hair regrowth.
The micro roller has been used for some years as an aesthetic treatment to reduce the appearance of scars and reverse the signs of ageing. As we age, components in the dermis such as collagen and elastin that provide the structure and elasticity in youthful skin, start to deplete and this can be made worse by environmental and lifestyle factors, such as pollution, stress, bad diet or smoking.
A dermaroller is a device covered with very fine needles that is run over the skin, causing tiny micro-injuries in the dermis. This triggers the body’s natural healing process and collagen and elastin production is stimulated to repair the damage.
Recently, its use as a hair regrowth therapy has been explored and there’s evidence it can help with hereditary hair loss or androgenetic alopecia. When the device is run over the scalp, micro-injuries are made into the middle layer of dermis, promoting collagen production and also stimulating the hair follicles. This can result in the thickening of thinning hair and even producing new hair growth. Microneedling can also promote the absorption of topical hair regrowth products such as minoxidil.
