What is a derma roller?

A derma roller is a handheld tool used for microneedling. It has a small wheel covered in tiny needles.

When rolled over your skin or scalp, it creates microscopic punctures, triggering collagen and elastin production and increased blood flow to rejuvenate your skin and thicken your hair.

It's designed to induce your body's natural healing mechanisms, primarily through the production of collagen and elastin. These proteins help rejuvenate your skin and restore its firmness and elasticity.

It's effective if you have stretch marks, acne scarring, and fine lines. It also helps to exfoliate dead skin cells, promoting a healthier scalp and hair.

If you are already using hair loss serums and oils, we recommend you try using a derma roller as a complementary product. Its role is to invigorate circulation and increase the potency of other topical solutions.

How do derma rollers stimulate hair growth?

Derma rollers aid your hair growth through microneedling. The tiny needles puncture your scalp, stimulating increased collagen and elastin production and blood circulation to the hair follicles.

A derma roller is a very effective complementary tool because it enhances nutrient delivery and the absorption of topical treatments.

The tiny needles create microscopic channels allowing oils and serums to penetrate deeper into your scalp, optimizing their effects to improve your hair density.

In a 2013 study, the results showed that microneedling therapy along with minoxidil was statistically superior to minoxidil alone in promoting new hair. It's one of the most promising non-invasive hair loss treatment options.

How to choose the right derma roller for hair growth?

If you want to select the right derma roller, first of all, you should consider the needle size. Between 0.5 mm to 1.0 mm is the safest for at-home derma rolling. The materials are also important. Durable titanium or stainless steel needles are the most recommended, but you should always opt for a reputable brand to ensure quality and safety.

Needle length

Derma rollers can have different needle lengths ranging from 0.25 to 1.5 millimeters. If you are looking for a derma roller for hair growth, the ones with 540 short microneedles (0.5 mm) are typically the most recommended.

The best needle length can vary depending on your goal. These needles can effectively stimulate your scalp without causing excessive discomfort or injury.


The tiny needles are commonly made with either stainless steel or titanium. While both materials are effective, titanium is often preferred for its durability and longevity.

We also recommend medical-grade stainless steel needles if you're going with that option.

Brand reputation

Always select a derma roller from a reputable brand to ensure the device is of high quality and safe to use.

It's also advisable to read user reviews before purchasing a derma roller to understand its pros and cons from those who have used it.

Remember, the effectiveness of the derma roller not only depends on its use but also on its quality.

                          How do you use a derma roller for hair growth?

                          derma roller before and after

                          To use a derma roller for hair growth, first, sanitize the roller with rubbing alcohol. Apply hair growth serums or oils to the scalp, then gently roll the derma roller over the treatment area in multiple directions. Clean the used at-home derma roller after each use and replace it when necessary, usually after two months or if needles become damaged.

                          With the right technique, at-home treatments can replicate professional treatment results. Follow these 5 steps to make sure you get the most out of this at-home derma rolling:

                          1. Sanitise after every use

                          After using a derma roller, you first need to rinse it under warm water and sanitize the roller with at least 70% ethyl alcohol cleaner. This also helps protect the material against any potential rust.

                          Of course, you can always clean it before use, both are acceptable!

                          This step is significant as the derma rolling results in the creation of tiny punctures. It's possible that improper cleaning might lead to skin infection.

                          Takeaway: Disinfect with at least 70% ethyl alcohol and let it dry.

                          2. Apply serums or oils

                          Now, the question is how to apply minoxidilhair growth serums, or hair growth oils with a derma roller to grow hair (and facial hair, if that's your jam) more effectively.

                          We, at Scandinavian Biolabs, believe it starts at picking the right serum.

                          Our Bio-Pixilin Activation Serum isn't just another hair product.

                          It's a carefully crafted blend of plant-powered ingredients, tailored to complement your derma roller and maximize its benefits.

                          It enriches your scalp, and the derma roller ensures that this goodness reaches where it matters the most - your hair follicles.

                          So, if you're serious about hair growth, consider adding the Bio-Pixilin Activation Serum to your derma roller routine.

                          It's the missing piece in your hair growth puzzle, and with it, you're one step closer to achieving the fuller hair you've always desired.

                          After all, when it comes to hair growth, every detail matters.

                          Bio-Pilixin® Activation Serum | For Men
                          Drug-free & clinically tested
                          Bio-Pilixin® Activation Serum | For Women

                          Drug-free & clinically tested

                          A cardinal rule: never put the serum on the device itself. You can apply it using the included pipette or cotton balls by sectioning your hair into parts and then massaging your hair.

                          Remember, it's important to follow the instructions on the label to ensure it works.

                          Takeaway: Apply products on your scalp first.

                          3. Derma roll in multiple directions

                          It's recommended to start derma rolling or micro needling on clean and wet hair to reduce friction that might irritate your skin.

                          Then, start gently rolling your scalp with not too much pressure in multiple directions - horizontally, vertically, and diagonally.

                          Remember, light pressure is enough when using a derma roller - there's no need to press hard.

                          Takeaway: Clean your scalp, wet your hair, and derma roll in multiple directions.

                          4. Replace when necessary

                          what derma roller for hair growth to buy

                          It's important to keep track of how long you've had your derma roller and what condition it's in. A premium derma roller can last a really long time, but, typically, you should think about getting a new derma roller every two months.

                          If your derma roller gets damaged or broken, you need to stop using it right away. Using a derma roller with bent or damaged needles can hurt your hair follicles and roots.

                          There are replacement heads for derma rollers that are more budget and environmentally friendly available on the market.

                          Takeaway: If the needles look crooked or damaged, it's time to toss them and get a new one.

                          5. Don't disturb the healing process

                          The healing process shouldn't be rushed or disrupted. As a rule of thumb, allow a few days of healing before you engage in another microneedling session.

                          Certain treatments can be applied during this period to expedite the healing process of the scalp if needed. Consult a healthcare professional about what drugs can you use.

                          Takeaway: Your scalp needs time to heal after each session.

                          What essential oils are best to use with your derma roller?

                          Essential oils that complement derma rolling for hair growth include rosemary oil to regulate sebum and boost circulation, lavender oil to encourage hair growth, peppermint oil to stimulate new hair growth and relieve itches, and coconut oil to rejuvenate skin and hair damage prevention.

                          Lavender oil

                          lavender oil

                          Oil from lavender flowers has powerful antibacterial and antifungal properties. The lavender essential oil is effective at stimulating hair growth.

                          Research published in 2016 indicated that administering lavender oil topically to animals increases growth. In addition, the rate at which their hair grew was much quicker than average.

                          It is also effective against head lice and other fungal diseases of the scalp that may inhibit hair growth factors.

                          Combining lavender oil and derma rolling is a great way to make hair grow faster and help treat hair loss.

                          Rosemary oil

                          rosesmary oil promote hair growth

                          Rosemary oil makes an excellent pairing with derma rollers for several reasons:

                          • Its lightweight texture doesn't leave your hair feeling oily, ensuring your hair remains fresh after application.
                          • Its ability to regulate sebum production on the scalp. This function keeps your hair and scalp from becoming overly greasy, preventing it from looking weighed down and flat.
                          • Rosemary oil is rich in antioxidants. These powerful compounds not only delay premature hair greying but also boost scalp circulation, contributing to quicker hair regrowth.
                          • Rosemary oil addresses the common issue of scalp acne. Thanks to its soothing and antifungal properties, it can alleviate itchiness while keeping the scalp clean and healthy.

                            Peppermint oil

                            peppermint oil

                            Peppermint oil works wonders for a scratchy, itchy scalp. Its antimicrobial properties effectively clear the scalp of excess oil and buildup.

                            One study, backed by a certified organic products agency, explored peppermint oil's hair growth effects compared to other oils. With 100% pure, natural peppermint oil, they discovered that, after four weeks, peppermint oil induced more hair growth than other tested oils.

                            Peppermint oil also unclogs pores, allowing the skin to breathe. When paired with a derma roller, the oil's penetration into the scalp is enhanced, fostering better hair growth.

                            Coconut oil

                            coconut oil

                            Coconut oil is widely recognized for its potent benefits for hair health and growth. One study revealed that coconut oil is absorbed better by individual hair strands than mineral oil and other alternatives.

                            It prevents hair damage, including split ends and hair breakage, contributing to the appearance of faster and healthier hair growth.

                            When used with a derma roller, coconut oil's performance is even more impressive. It's packed with antioxidants, lipids, and vitamins that help combat frizz, treat dandruff, and mend split ends.

                            Coconut oil can be your go-to remedy for androgenetic alopecia issues. Teamed with a derma roller, it can significantly boost your hair's health and quality.

                            Pros and cons of a derma roller

                            Derma rolling has impressive hair growth benefits, but it also has its own drawbacks compared to conventional therapy and other hair loss treatments:


                            • It enhances the absorption of other hair treatments so if you are looking to achieve results faster, might be worth giving it a shot.
                            • It increases elastin and collagen production which help rejuvenate your skin and restore its firmness and elasticity.
                            • It increases hair growth and fights hair thinning so you can feel more confident again
                            • It promotes smoother and firmer skin meaning if you are battling with acne or scars, this might be the tool for you
                            • It alleviates fine lines and stretch marks making your skin and scalp look and feel healthier


                              • Using a derma roller requires a healing period and consistent use. Don’t get discouraged if it takes more time to see the results - your patience and dedication will pay off eventually!
                              • There is a risk of infection, so don't skimp on a low quality one or use a damaged derma roller. Always follow the instructions, disinfect and use it safely!
                              • It can irritate potential side effects meaning if you have any pre-existing health or skin conditions, you should consult a doctor first.

                                What are the potential 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.


                                Why isn't your derma rolling working?

                                If your derma rolling isn't showing results, it could be due to a variety of factors. These may include choosing an incorrect needle size, inconsistent usage, not following the right rolling technique, or failing to care for your skin after derma rolling.

                                If you have a medical condition affecting your skin or hair, it might interfere with the outcome. Remember, derma rolling requires consistent use over several weeks to see visible results.

                                Who shouldn't use derma rollers?

                                It's recommended to consult a doctor before starting derma rolling if you have any pre-existing health or skin conditions:

                                • Active acne or contagious skin diseases
                                • Sun damage or sunburn
                                • Sensitive skin conditions

                                Don't hesitate to seek medical advice if you're unsure about any aspect of this cosmetic treatment for your skin type.

                                When to contact a doctor?

                                If you notice severe discomfort, heavy bleeding, signs of infection, or worsening hair loss after using a derma roller, it's essential to contact a healthcare professional.

                                Are derma rollers good for hair loss?

                                Yes, derma rollers can help treat hair loss or androgenetic alopecia. They induce minor injuries to the scalp, prompting the body's healing response. This process improves blood circulation. When combined with topical hair loss treatments, the results could be even more pronounced. However, individual results may vary.

                                How many times a week should I derma roll?

                                The recommended frequency of derma rolling depends on your derma roller's needle length. For smaller needles (0.25mm to 0.5mm), you might use them up to three times weekly. For larger needles (0.75mm to 1mm), once a week or every other week could be optimal. Always give your skin time to recover between sessions.

                                Is it okay to use a derma roller every day?

                                Using a derma roller daily is generally not recommended. Overuse can lead to skin irritation and potentially harm the scalp, disrupting the healing crucial for hair regrowth. With smaller needles (0.25mm), daily use might be acceptable, but it's typically advised to allow at least a day of rest between sessions for healing.

                                What are the results of a 1-month derma roller treatment?

                                The outcomes of a 1-month derma roller treatment can vary based on factors like needle size, how often you use it, and your skin and hair health. Some might observe initial improvements such as less hair fall or thicker hair. However, noticeable hair growth usually takes a few months of regular use. It's crucial to understand that derma rolling is a gradual process and to keep realistic expectations.


                                To sum up, if you only have money to buy one tool for hair growth, you should choose a derma roller. It stimulates collagen creation, blood flow, and cellular regeneration, which means that it can definitely help if you are facing issues such as losing or thinning hair.

                                It can be especially effective if you combine it with other hair growth products such as serums and oils as it improves the absorption, optimizing their effects to improve your hair density.

                                When you use a derma roller you need to consider the needle size, the application technique, and hygiene practices. But with the right approach, it can be a powerful addition to your hair care regimen.

                                However, you should always maintain realistic expectations, consult professionals when needed, and explore other hair loss treatments as part of a comprehensive approach to your hair health.
