Why are derma rollers used for hair growth?

A derma roller (also known as a microneedle roller) is a small skincare device that consists of a handle with a roller head covered in tiny, fine needles. While the primary purpose of a derma roller is to stimulate the skin’s wound healing response and improve skin texture, some studies show that derma rollers also stimulate hair growth, especially if paired with a medication such as topical minoxidil1. 

Does derma roller work for hair regrowth?

Dr. Alpana Mohta, board-certified dermatologist, says that the idea behind using a derma roller for hair regrowth is that the micro-injuries created by the tiny needles can stimulate blood circulation, increase collagen production, and potentially rejuvenate hair follicles, leading to thicker and healthier hair growth2. However, more scientific evidence is needed to establish the effectiveness of derma rollers specifically for hair regrowth.

How to get a prescription for hair growth?

You can start a consultation with an online dermatologist via Miiskin. First-time consultation is $59 and the price for returning patients is $39 only.

Benefits of using a derma roller for hair growth

Studies show that repeated microneedle stimulation promotes hair growth3. Derma rollers are devices designed for home use to stimulate hair growth in the scalp and face. 

The concept of derma rolling is based on the principle of micro-needling, where the micro needles create tiny holes (injuries) in the skin promoting the wound-healing response on the skin and activating growth factors4.

Stimulates hair growth on scalp

Through the stimulation of collagen production and enhanced blood circulation to the hair follicles, derma rolling has the potential to enhance hair growth in regions where hair is thin or uneven5.

Enhances blood circulation

Utilizing a derma roller entails needle penetration, resulting in minor skin micro-injuries that initiate the body’s innate healing process. This, in turn, enhances blood circulation in the targeted region, promoting an improved growth of hair due to a better  blood flow.

Boosts the efficacy of hair growth treatment

Studies show that using topical minoxidil and a derma roller improves the absorption and effectiveness of the medication since the needles create micro-channels that allow for a better penetration of the product into the skin6.

Boosts growth factors

When you use a dermaroller on your scalp, it creates tiny wounds. This process activates growth factors. These growth factors are like special messengers that tell your scalp’s hair follicles to start repairing themselves, and this includes making your hair grow.

Stimulates stem cells

Your hair follicles have stem cells. Stem cells in hair are like master cells that can turn into any type of cell needed for hair growth and repair. The micro-injuries caused by a derma roller make the stem cells jump into action to heal these injuries, which also encourages hair to grow.

Turns on hair growth genes

Healing of micro-injuries caused by a derma roller increases the activity of many genes that are important for growing hair.

 Convenient and budget-friendly

Using a derma roller is a relatively affordable and straightforward process that can be done in the comfort of your own home. The device can be rolled across the scalp in various directions to ensure even coverage.

    Medications for Hair Loss: What You Need to Know

    • Oral vs topical minoxidil: Which works better for hair loss?
    • Finasteride vs minoxidil: Battle of hair loss titans
    • Dutasteride vs finasteride for male androgenetic alopecia
    • Is minoxidil over the counter?
    • Oral finasteride for hair growth

    Should I use topical minoxidil with a derma roller to get better results?

    Using topical minoxidil and finasteride together with a derma roller for hair growth is a common approach if you want to achieve more dramatical results. The idea behind this combination is to enhance the effectiveness of minoxidil and finasteride by increasing its absorption into the scalp when applied 24 hours after derma rolling. 

    However, before starting any new hair regrowth regimen, it is essential to consult with a dermatologist. They can assess your specific hair loss condition and provide personalized advice on whether minoxidil is right for you, or if there are other treatments that would suit your type of hair loss best.

    Can I use oral and topical minoxidil for better hair growth results?

    Yes, absolutely! You can combine oral and topical minoxidil to get faster and more dramatic results. To learn more about minoxidil for hair growth read our dermatologist guide: Using minoxidil for hair growth

    How to get a minoxidil prescription for hair growth?

    You can get a minoxidil prescription for hair growth by having a photo-consultation with an online dermatologist. The dermatologist will assess if minoxidil is right for you and in less than 2 business days you will get your answer. 

    Which derma roller size is best for hair regrowth?

    Dr. Mohta says that when using a derma roller for hair regrowth, it is important to be cautious and start with the shorter needle length if you are inexperienced or have sensitive skin. As your scalp gets used to the process and you assess how your skin responds, you can gradually increase the needle length if needed. 

    0.25mm derma roller

    This needle length is suitable for beginners or individuals with a lower pain tolerance. It is less likely to cause discomfort and is ideal to enhance product absorption and stimulate the scalp without causing a deeper skin penetration.

    0.5mm derma roller

    This needle length is slightly longer and can penetrate the skin more deeply. It may provide more stimulation to the hair follicles and could be more effective for hair regrowth, but it may also be more uncomfortable for some people.

    How to use a derma roller for hair?

    Using a derma roller for hair involves a specific process to maximize its potential benefits while minimizing the risk of discomfort or complications.

    Keep your hair short

    To get better results with a dermaroller for hair growth, it is generally advised to keep your hair short. Short hair allows the dermaroller to reach the scalp more easily, ensuring better contact with the skin.

    Wash your hair and scalp and let it dry completely

    Wash your hair and scalp with a mild, sulfate-free shampoo and either blow dry it or let it air dry until it is completely dry. 

    Sanitize your derma roller

    After your hair is fully dry, clean your derma roller with rubbing alcohol to prevent infection.

    Divide your scalp into sections

    Divide your scalp into sections, especially if you are targeting specific areas with thinning or hair loss. This will help you ensure even coverage and avoid over-treating one area.

    Roll gently

    Hold the derma roller at a 45-degree angle to your scalp. Begin by gently rolling it back and forth over one section of your scalp. Avoid pressing too hard, as this can cause discomfort or damage. You should feel a mild tingling sensation but not significant pain.

    Change directions

    After a few passes in one direction (e.g., vertical), change the direction to roll horizontally and then diagonally. This ensures that you create tiny micro-channels evenly across the treated area.

    Avoid rolling over open wounds

    Do not use the derma roller on any open wounds, inflamed areas, or active skin conditions.

    Wait before applying products

    After using the derma roller, it is best to wait 24 hours before applying any products, including minoxidil or other hair growth treatments. This allows your scalp to recover from the micro-injuries created by the derma roller.

    Clean the derma roller

    After each use, thoroughly clean the derma roller with rubbing alcohol and allow it to air dry before storing it in a clean, dry place.

    How often should I use a derma roller for hair growth?

    Dr. Mohta says that the frequency of using your dermaroller for hair growth varies depending on individual preferences and sensitivity. Some people may do it once a week, while others do it every two weeks or twice a week. Starting with a less frequent schedule and gradually increasing it based on your comfort and your scalp’s response is a good approach.

    Dr. Mohta says that you should be patient, as it may take several months before you see noticeable results, and individual responses can vary. If you experience any adverse reactions or discomfort, discontinue use and seek professional advice.
