If you've tried everything to treat hair loss and grow new hair, it's time to try using the derma roller.

Early results show derma rollers effectively stimulate hair growth and reduce hair thinning and hair loss within weeks.

Could this tool finally be the answer?

We asked UK board-certified dermatologist Dr. Chaudhry to answer all of that & we tested the best derma roller for hair growth in 2024.

What is a derma roller?

derma rolling for hair regrowth

A derma roller is a tool used to stimulate hair growth on the scalp. It is a roller covered in tiny needles that create micro-injuries in the skin. This triggers the body's natural wound healing response, which can increase blood flow to the scalp and collagen production. These factors may enhance hair growth and help promote healthier hair.

In a randomized evaluator-blinded study conducted in 2013, microneedling therapy along with minoxidil was statistically superior to using minoxidil alone in promoting new hair.

Benefits of using a derma roller for hair regrowth

Derma rollers can work for hair growth. While the research isn't conclusive, there are some potential benefits of using a derma roller:

  • Increased Blood Flow: Derma rollers create tiny pricks in the scalp, which triggers the body's natural healing process. This can increase blood flow to the area, bringing more nutrients and oxygen to your hair follicles. Improved circulation can potentially promote healthy hair growth.
  • Enhanced Absorption of Hair Products: Microneedling with a derma roller can create temporary channels in the scalp, which may allow for better absorption of minoxidil or other hair loss treatments that you might be using. This could potentially improve their effectiveness.
  • Stimulates Hair Follicles: The micro-injury from derma rolling may send signals to the scalp to boost hair follicle activity and growth factors.

How long does derma roller take to grow hair?

It likely won't be for at least a few months before you see any noticeable results from a derma roller. Here's what will typically happen:

  • Initial shedding: You might actually experience some shedding in the first few weeks of using a derma roller. This is because the derma roller stimulates the scalp and pushes out hairs that are already in the telogen (shedding) phase.
  • Slow growth: After the initial shedding, new hair growth will likely be slow and gradual. It can take 2-3 months to see any visible improvement, and it may take 6 months or more to see the full effects.
  • Consistent use: Be patient and consistent with your hair regrowth regimen. Regular use of 1-2 times per week is the best for hair growth results.

How to choose the right derma roller for hair loss?

Choosing the right derma roller for hair growth involves understanding two key factors: material and needle size.

Here's a breakdown to help you pick the perfect one:

Construction materials

Look for derma rollers made with medical-grade materials like stainless steel or titanium. These ensure the needles stay sharp and effective for multiple uses. Avoid using silicone or plastic derma rollers.

Derma roller size

    Derma roller size is the most crucial aspect. For scalp use, aim for needles between 0.25mm and 1.0mm. Here's a breakdown of different needle sizes:

    • 0.25 mm: Good for those with sensitive scalps. It creates mild stimulation but is not as effective for optimal results.
    • 0.5 mm: A great middle ground, balancing stimulation, and minimal discomfort. This size is widely available and a good starting point for most people.
    • 0.75 mm - 1.0 mm: These needles penetrate deeper, potentially leading to better results. However, they also come with a slightly higher risk of irritation and require a bit more scalp tolerance. It's important to assess your scalp sensitivity before going this high.

    How did we test?

    derma roller test before and after

    For this evaluation, we recruited a panel of testers with varying scalp conditions to ensure well-rounded results.

    We implemented a controlled, double-blind study. Testers used assigned derma rollers for a set period, documenting ease of use, any side effects, and perceived hair growth progress.

    We then combined dermatologist-evaluated "before and after" photos with user feedback to determine the most effective and user-friendly derma rollers for hair growth.

    Below are the 7 best results from over 20 tests.

                        How to use derma rollers for hair growth results?

                        what derma roller for hair growth to buy

                        Here's a guide and tips on how to use a derma roller. Here are 7 steps you need to do to see results from microneedling with a derma roller:

                        What you'll need

                        • A derma roller
                        • A disinfectant solution (i.e. 70% isopropyl alcohol)
                        • A topical hair loss treatment.


                        1. Cleanse your scalp: Wash your hair and scalp with a gentle shampoo and thoroughly dry your scalp (let it air dry or blow dry).
                        2. Disinfect the derma roller: Soak the roller head in disinfectant solution for 10-15 minutes. Rinse thoroughly with sterile water and pat dry.
                        3. Prepare the treatment area: Part your hair to expose the scalp areas you want to target.

                        Using the derma roller

                        1. Apply gentle pressure: Gently roll the derma roller across the scalp area in vertical, horizontal, and diagonal motions. Apply light, even pressure to create micro-channels. Each area should be rolled 4-5 times in each direction.
                        2. Be mindful of sensitive areas: Avoid rolling over moles, blemishes, or irritated skin.
                        3. Target specific areas: Focus on areas with hair thinning or loss. Ensure even coverage.

                        After derma rolling

                        1. Disinfect the roller again: Repeat the disinfection process as described earlier.
                        2. Soothe the scalp: Apply a calming, alcohol-free moisturizer to soothe any irritation.
                        3. Apply topical treatment (optional): If using minoxidil or similar topical treatments, apply it after derma rolling as it may enhance absorption.
                        4. Avoid certain activities: Avoid strenuous exercise, excessive sweating, swimming, and hot tubs for at least 24 hours after use.

                        Safety precautions

                        • Don't share: Derma rollers are for personal use only to prevent the spread of bacteria.
                        • Replace regularly: Replace your derma roller every 3-4 months to maintain needle effectiveness and hygiene.
                        • Be mindful of contraindications: Don't use a derma roller if you have active acne, open wounds, or certain skin conditions. Consult your doctor if unsure.

                        How often to use a derma roller for hair growth and hair loss treatment?

                        The best frequency for hair growth depends on the needle length you have:

                        • 0.5 mm needle length: Roll 1-2 times per week.
                        • 1.0 mm needle length: Roll 1-2 times every 2 weeks.
                        • 1.5 mm needle length: Roll 1 time every 3-4 weeks.

                          Most experts recommend no more than once per week maximum when starting out, to avoid over-treatment and skin irritation. Less is often more with derma rolling.

                          Side effects of derma rolling

                          Derma rolling can cause skin redness, irritation, and slight swelling, similar to a sunburn. Rarely, it may cause bleeding or bruising. Improper use can risk scalp or skin damage, emphasizing the need for correct use and hygiene to avoid infection.


                          In conclusion, a derma roller presents a promising tool to promote hair growth. Through the stimulation of collagen creation, blood flow, and cellular regeneration, derma rollers may help to address issues of losing or thinning hair.

                          While their use requires careful consideration of factors such as needle size, application technique, and hygiene practices, with the right approach, they can be a powerful addition to your hair care regimen.

                          It's essential, however, to maintain realistic expectations, consult professionals when needed, and explore other hair loss treatments as part of a comprehensive approach to hair health.

                          Frequently Asked Questions

                          Can derma rolling treat male or female pattern baldness?

                          Derma rolling holds promise for both male and female pattern baldness. The tons of tiny needles create micro-injuries that trigger scalp healing, potentially improving blood flow and stimulating hair follicle function. Studies suggest it can boost hair count and density, and may even enhance the effects of other hair loss treatments like minoxidil.

                          Are microneedling and derma rolling different?

                          Dermarolling and microneedling for hair are both methods of creating tiny injuries in the skin to boost collagen production, but they differ in execution. Microneedling is typically an in-office procedure using a pen with adjustable needles that precisely target specific areas. Dermarollers, on the other hand, are at-home tools with a roller covered in short needles that you move across your skin.
