At-home scalp tools like derma rollers for hair growth are becoming a legit, derm-backed way to support regrowth and help your other hair-loss products work harder (more on how to use a dermaroller for hair growth here). So, if you start noticing a wider part, a thinner ponytail, or more strands in the shower as I did, there’s no need to panic.
Derma rollers (a.k.a. microneedling rollers) use tiny needles to create controlled micro-injuries on the scalp. That sounds intense, but it’s actually the point: it kicks off the skin’s wound-healing response, boosts circulation, and helps ingredients like minoxidil or hair growth serums penetrate better, says Joshua Zeichner, MD, a board-certified dermatologist. As long as you follow the device instructions and keep it clean, it’s generally safe to perform at-home microneedling procedures that use 0.5-mm needles or shorter, says Dr Zeichner.
Because not all tools are made for the scalp — and needle length really matters — I decided to work with expert Glamour editors to test the most popular options on the market. The result? An edit of derma rollers for hair growth that we found to be actually comfortable to use, well-designed, and efficacious. Once I had all of the reviews in, I determined that our top pick is the Vegamour 0.25 mm GRO+ Advanced Scalp Dermaroller, which stood out for its beginner-friendly needle length and scalp-specific design, but I'm currently testing the UKLash Advanced Scalp Derma Roller, too, which (based on our love for their eyelash growth serum and scalp serum), I'm expecting to adore.
The best derma rollers for hair growth, at a glance
How I tested derma rollers for hair growth
It's very important to us that we test every product that we feature – so that you can trust our recommendations and so that you don't waste your money. Testing is, of course, an on-going process, but we always specify which products have completed testing, which are still being tested, and which have become reliable parts of our routines post-testing. We endeavour to test new launches and film refreshed review videos at regular cadence.
To find the best derma rollers for hair growth, I worked with Glamour US and UK editors to test a range of tools across different hair types, concerns, and budgets.
Each roller was used consistently over several weeks and evaluated based on how easy it was to incorporate into a regular routine, how well it stimulated the scalp without irritation, and whether it seemed to improve product absorption. We prioritised high-quality materials — such as titanium or stainless steel needles — made by brands we trust. We also considered factors including needle length, roller design, and ergonomics. The best-performing options were gentle yet effective, comfortable to use, and made a visible difference in hair and scalp health.
Why you can trust me:
I am a journalist with eight years' of experience testing fashion and beauty product launches. I worked for two years at Hitched UK, and for the past years, I've spearheaded the testing of new beauty products for Glamour. During that time, I've not only witnessed the rise of the at-home hair growth sector (with shampoos for thinning hair, hair masks for hair growth and biotin supplements for hair growth all becoming big news), but I've seen lots of other trends come and go, too.
I've attended press days, interviewed doctors, hair stylists, dermatologists and trichologists, and I test hundreds of products every year. As such, I know more about brands, new launches and which products are worth your money than your average beauty fan.
To ensure I am an authority on derma rollers for hair growth specifically, I've read scientific papers and interviewed experts to learn more about the subject. You can find my list of interviewed experts at the bottom of the page, and read more about how we test here.
Best Overall: Vegamour 0.25 mm GRO+ Advanced Scalp Dermaroller
- Pros: Wide head covers more scalp; replaceable head every 30 days to avoid dulling, ineffective needles; designed to pair with Vegamour GRO+ serum
- Cons: Lower needle depth might not provide maximum stimulation on the scalp
- Needle Size: 0.25 mm
Codeveloped with a dermatologist, this scalp derma roller from Vegamour is our favourite amongst the bunch, thanks to its wide head and easy-to-use design. Not only is this tool ergonomic and sturdy, but its gold-plated finish and chic carrying case make it an elegant addition to your haircare routine. Plus, we love that the roller head is slightly wider than a face roller, so you can cover more scalp in fewer passes. That’s super helpful if you’re targeting the crown or part line. Unlike other derma rollers that need to be completely disposed of after a few months because of dulling needles, it’s easy to replace the head on this tool every 30 days for optimal use. It can be used with the editor-tested Vegamour GRO+ Advanced Hair Serum for more effective absorption.
Glamour contributor Emily Tannenbaum was thoroughly impressed by her results. “It really seems like the trouble spots on both sides of my hairline filled in, and I don’t notice as many gaps in photos or close up,” she says. “The sensation felt really good on my temples, and I loved how luxurious the wand was compared to other derma rollers I’ve tried in the past. The trick is that consistency is key—I used the roller every morning and night for nearly a month.”
The Runner-Up: BUR BUR Growing Season Derma Roller
- Pros: Uses individual titanium linear needles for lightweight, precise punctures, with less irritation
- Cons: 0.3 mm depth might still be too mild—it may take longer to see results than deeper needles
- Needle Size: 0.3 mm
What sets this derma roller apart is the needle type. Instead of a roller with 540 tiny disk needles, it uses individual titanium linear needles, which create more precise micro-punctures and can feel less scratchy on the scalp. This needle type reduces the scalp irritation that can sometimes happen. “I would assume that the titanium needles are stronger and will resist getting dull with continued use, ultimately giving better quality treatments with less potential irritation to the scalp,” explains Dr Zeichner. Lightweight and travel-friendly, this pick comes with a little carrying case to keep it clean between uses.
“I’ve been using this roller for almost two months—about twice a week, followed by a hair oil (I used the Bur Bur Botanical Oil, but you can use any, according to the instructions). This was following a period where my hair was falling out in clumps, due to stress, menopause, and years of bleaching. The fallout slowed down in my second week of using the derma roller. I’m not sure how much new growth there’s been in that time, as it’s only been a few weeks, but my hair also feels thicker and softer. The roller itself feels a little prickly, like the way a small cactus feels, but it’s nothing too uncomfortable. I look forward to using this tool some more to observe any new growth, but I’m encouraged by the new thickness and softness of my hair,” says Glamour contributor Charlotte Twine.
Best for Hair Thinning: BeautyBio GloPRO Microneedling & Healthy Scalp Hair Density Treatment Set
- Pros: One of the few at-home hair derma rollers that combines microneedling and red light therapy; replaceable microneedling attachment; good for sensitive scalps
- Cons: Pricey, requires replacement of MicroTip heads ($59) every 3–4 months
- Needle Size: 0.3 mm
This is the most high-tech derma roller version on this list. Recommended by Dr Zeichner, it combines microneedling with red light therapy to encourage healthy hair growth. Research suggests that red light therapy may help keep hair follicles in their growth phase (anagen) for longer, rather than shifting into the shedding stage (catagen) too soon. “Red light has been shown to enhance circulation to the scalp, reduce inflammation, and boost mitochondria function for optimal cellular activity,” says Dr Zeichner.
“This hair-loss treatment is pretty pricey, but with the amount of items included, the decent results, and the quality of the derma roller and serum, I would say it’s worth the extra money. The derma roller is battery-powered and vibrates upon application. It also includes red light, which you don’t see often with other derma rollers on the market. The needle length is 0.3 mm, which isn’t too short, but also isn’t super long—perfect for my sensitive scalp. I tested this device along with the serum for about a month, and while I did notice some baby hairs popping up along my hairline, as well as a scalp that looked a bit denser, I can’t say I’ve seen insane results just yet—I think I need to keep using it for a bit longer. One thing I’m thoroughly impressed with, though? The fact that this device and serum didn’t irritate my super sensitive scalp,” says Glamour contributor Daley Quinn.
Best for Face & Scalp: Kitsch Micro Derma Roller
- Pros: Gentle 0.25 mm length, good for beginners and sensitive users; works on face and scalp
- Cons: Shorter needles may not stimulate as deeply as scalp-only tools
- Needle Size: 0.25 mm
This is a gentle, beginner-friendly roller that can be used on your face and scalp.The 0.25 needle length makes this a great option for folks with more sensitive skin. Designed to help enhance the absorption of skin care, haircare serums, or topical treatments, this affordable tool is really lightweight and feels easy to manoeuvre around the face and scalp.
“For anyone who is starting out with dermarolling and doesn’t want to spend a ton of money on a tool, I would definitely recommend this one from Kitsch. I love that you can use this for both your face and scalp—I, miraculously, didn’t experience any sensitivity or bad reaction after testing this for a month, even though I have really sensitive skin. One of the things I will note about this pick is that the needles are on the shorter end—because of this, you might not get as deep into the root and scalp as you would with a 0.5-mm derma roller tool,” says Glamour contributor Daley Quinn.
Best for Beard: The Beard Club Beard Derma Roller
- Pros: Titanium-coated needles are durable; designed for beard areas
- Cons: Designed for face, not ideal for full scalp use
- Needle Size: 0.25 mm
Highly rated on Amazon, The Beard Club Beard Derma Roller is ideal for those who are struggling to grow a beard. That being said, it’s important to keep in mind that “if there are no grass seeds in the yard, no amount of fertiliser will grow you a full yard,” explains Dr Zeichner. Meaning, “microneedling in the beard can help enhance growth, whether there are weak follicles or thin hair, but it will not grow hair in patches where you never had it.” This pick has 0.25-mm needles and is deep enough to penetrate the skin, even through thick facial hair. It can also be used on your face and scalp. Just make sure to properly disinfect it after each use, and replace the roller head every month for optimal use.
Currently Being Tested: UKLash Advanced Scalp Dermaroller
- 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.
