Microneedling is another name for Collagen Induction Therapy (CIT) and is commonly associated with the dermaroller.A derma roller is a handheld device with a wheel attached to a handle. The wheel is outfitted with tiny needles, just a few millimeters long. The device is rolled over the skin, causing the needles to press against the tissue. Originally, the derma roller was used to address skin imperfections, but a manufacturer has begun to market one model to the public as a treatment of androgenic alopecia.
Hair growth relies on genes that promote the development of new hair cells. This takes place within the hair follicles, the small openings that cover the scalp as well as the rest of the body. A number of chemicals are needed to trigger the production of hair cells, and one of the most important of these is the human growth factor.
Having studied and tested this product I have found it to be an excellent weapon in the fight against hair loss. The theory behind the Dermaroller is absolutely in sync with my theories on hair loss and hair growth.
The Dermaroller works by causing very minor damage to the skin (puncturing the skin with the tiny needles). This encourages the skin to regenerate and heal, where it would otherwise not do so.
Because the Dermaroller stimulates regeneration in the areas it is applied to, it can also work to stimulate hair re-growth (in places where hair loss has occurred). Stimulating blood circulation is a proven way of stopping hair loss and encouraging hair growth because it increases the supply if raw materials to the hair, thus encouraging increased growth.
Increased blood circulation in the scalp may also help reduce DHT levels in the scalp because the increased blood flow may help remove more DHT from the hair papilla –providing there is less DHT in the blood than there is in the papilla it travels to and from.
