Micro Needling for Hair Growth


Can micro needling with a derma roller stimulate hair growth?


Primarily used as an anti-ageing skin treatment, micro needling has also been found to be an effective treatment for varying types of hair loss. There is sufficient evidence that micro needling can stimulate the growth and regrowth of hair.

Micro needling has become a popular method of treating hair loss in both men and women. Patients have experienced visible improvements in the hair growth around the frontal hairline, centre parting area of the scalp, and the crown region.


What is micro needling?

Micro needling is a process whereby one punctures tiny wounds into the skin using a derma device. A production of protein and collagen is formed during the repair stages, which, in turn, helps regenerate and revitalise the health of hair follicles.

Micro needling can be done by using one of two derma devices - a derma roller or a derma pen/stamp. Both derma devices are effective, so it depends on what the individual is more comfortable with using. Derma rollers tend to be better for shorter hair, due to the risk of pulling and tangling, whereas derma pens and stamps are more suitable for longer hair.

The purpose of micro needling, in the case of treating hair loss, is to stimulate dermal papilla, or the stem cells in hair follicles, to encourage growth factors. The idea is that by creating the tiny wounds in the skin, the body's natural defences then encourage the repairing process, which ultimately leads to the production of new hair growth.

Derma rolling has been shown to be even more effective for hair growth when used alongside a topical treatment such as minoxidil or
keratinocyte growth factor serum. The combination the micro needling and topical treatment, can help stop hair loss and regrow hair.


How often should you micro needle for hair growth?

You can micro needle twice a week using a 0.5mm - 0.75mm needle, or you can micro needle just once a week with a 1.0mm - 1.5mm needle. There is no difference in effectiveness - it depends on what the user is more comfortable with. Using a longer needle will cause more discomfort, but it only needs to be done once a week. The shorter needle will be less painful, but needs to be used more often.
