If you start noticing a wider part, a thinner ponytail, or more strands in the shower, there’s no need to panic. 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.
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—we tested the most popular options to see which ones were actually comfortable to use, well-designed, and worth buying. Our top pick, the Vegamour 0.25 mm GRO+ Advanced Scalp Dermaroller stood out for its beginner-friendly needle length and scalp-specific design, but we also have options for beards and hairlines.
The best derma rollers for hair growth, at a glance
How we tested
To find the best derma rollers for hair growth, we tested 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 prioritized high-quality materials—such as titanium or stainless steel needles—and 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.
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 favorite amongst the bunch thanks to its wide head and easy-to-use design. Not only is this tool ergonomic and sturdy, but its gold-colored plating and chic carrying case make this 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 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.”
Best for Scalp: 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.

- 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 maneuver 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 fertilizer 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.
Best for Product Absorption: iRestore ScalpStim Derma Roller
- Pros: Larger rolling area for faster coverage; easy to hold
- Cons: 0.5-mm depth may be too aggressive for very sensitive scalps
- Needle Size: 0.5 mm
This one is made specifically for the scalp, with a larger rolling area and a handle that sits in your palm. Dr. Zeichner recommends the iRestore ScalpStim Derma Roller to his patients: “It stays easily in the palm of your hand to use on the scalp.”
The needles on this derma roller are 0.5 mm long, which is about twice the length of your average derma roller needles. That can help with better scalp stimulation and product penetration, but it can also be too intense for sensitive types.
Frequently asked questions
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.
