- Pros: Affordable, we love UKLash as a brand already; it works well with the UKLash hair growth serum.
- Cons: We’re still testing this, so we’ll report back on the downsides.
- Needle Size: 540 0.25mm mini needles.
UKLash has been a brand that my fellow Glamour editors and I have loved for a really long time. Cast your mind back to 2024; I wrote about the launch of the UKLash LED face mask – which has since held its place as one of my forever-favourites in our guide to the best LED face masks on the market. As such, when we started to sort samples for the testing of derma rollers for hair growth, I was keen to get in on the UKLash action.
I’ve been regularly “slicking” my hair back for the past few years, and I’ve definitely noticed that my hairline has begun to thin – so it felt like perfect timing to really put the brand’s launch to the test. And, hopefully, notice the difference. The UKLash hair tool has been “expertly designed” with 540 0.25mm needles – I outlined in the introduction that needles should be 0.5-mm or shorter, so that’s great – which will penetrate the scalp to boost collagen production, stimulate the hair follicles, revitalise the environment at the root and boost the effectiveness of any topical hair serum.
While I need to report back on my findings, and add before and after photographs to this guide, I so far love that the tool is designed with a premium soft-touch finish, which makes using the tool easy and comfortable, and I love that it fits neatly into a carry case. I can take it away on holiday, and it’ll stay clean in my suitcase. The brand specifies that studies have shown that, when paired with topical solutions such as Hair Serum, microneedling can improve hair growth by up to 50%. So, I am excited to see my results.
Your dermaroller for hair growth questions, answered:
Which derma roller size is best for hair growth?
“Over-the-counter derma rollers are made with tiny needles that are no longer than 0.5 mm,” says Dr Zeichner. “Anything longer can increase the likelihood of scarring if not properly performed, so deeper needling procedures should be performed only by your doctor.”
Can derma rolling regrow hair?
Yes, dermarolling helps support hair growth by creating tiny micro-injuries in the scalp that boost collagen production, encourage blood flow, and enhance the absorption of hair-growth products. This can help reactivate dormant hair follicles and support healthier, thicker hair over time, according to Dr Zeichner.
How often should I use a derma roller for hair growth?
Most experts recommend dermarolling twice per week at first, then increasing to three times per week over the next few weeks if your scalp can tolerate it.
What products should you use after derma rolling?
After using the derma roller at home, you can apply your hair growth serum or minoxidil. “The derma roller can help enhance penetration of the growth serum through the outer skin layer for optimal benefits,” says Dr Zeichner.
