Everything you need to know about derma rollers for hair growth, according to experts

If you’re not seeing results from your serums, hair oiling, and scalp massage, it might be time to try derma rollers for hair growth. These microneedling tools can boost circulation and stimulate collagen. “Microneedling has been shown to stimulate hair growth by creating tiny micro-injuries that boost blood flow, trigger collagen production, and enhance absorption of topical treatments,” says trichologist Rachael Sey. Designed for DIY microneedling treatments, derma rollers boost cell turnover and help improve skin concerns, too.

But before you add derma rollers to your hair care routine, it’s worth getting a good handle on using them correctly, especially as misuse can potentially do more harm than good. To find out how they work, the right technique and the specs a quality derma roller should have, we called on certified trichologists for a derma rolling 101.

Can derma rollers help hair growth?

“Studies have shown that microneedling can help stimulate hair growth and benefit those with female/male pattern hair loss, doing so because they create a small controlled injury in the skin (your scalp) which subsequently results in the release of hair supportive growth factors,” says Anabel Kingsley, trichologist and hair health expert at Philip Kingsley haircare. Additionally, derma rolling helps to promote blood flow to the scalp, which helps with creating stronger and healthier follicles, as Hannah Gaboardi, resident trichologist at Nobu Hair Growth Clinic, explains. “This can also help activate dormant follicles, stimulating new growth and more density.”

Anecdotally, there’s a lot of evidence that dermarollers can help with everything from bald spots to beard growth, with users seeing impressive results after consistent use. But, as Dr Tatyana Lapa-Enright, aesthetic doctor and the founder of Hardwick Clinic, tells us, these results depend heavily on technique and the quality of your device and products. Ideally, Kingsley recommends seeing a trichologist or dermatologist for microneedling, as trained professionals can control needle depth and monitor results. “If you do decide to do it at home, follow all precautionary steps,” she cautions.

How to use derma rollers for hair growth

1. To begin, ensure your dermaroller is sterilised for hygienic use. It is recommended to start on clean, dry skin, though some people prefer to apply a small amount of hydrating serum first to help with glide.
