Derma rollers, a popular tool in the beauty and wellness industry, are making waves for their potential benefits in promoting hair growth. 

This simple, handheld device, covered with tiny needles, is designed to stimulate the scalp, potentially encouraging hair regrowth and enhancing the effectiveness of topical treatments. 

But do they really work? In this blog, we'll explore the science behind derma rolling, its methodology, and how it could be a game-changer for those struggling with hair loss. 

From understanding its mechanism to evaluating its efficacy, we'll cover everything you need to know about derma rollers and hair growth.

What is a derma roller?

A derma roller is a skincare device with numerous small, fine needles. It creates micro-punctures on the skin's surface, stimulating its natural healing process and promoting collagen production.

The derma roller addresses skin concerns on various body parts, including the face and scalp. These tiny needles, when rolled over the skin, create micro-injuries.

This process triggers the body's wound-healing response, enhancing collagen and elastin production—crucial for maintaining the skin's elasticity and firmness, which is essential for both skin rejuvenation and beard hair growth.

This mechanism helps reduce the appearance of scars, wrinkles, and fine lines and is believed to stimulate the hair follicles when used on the scalp, potentially promoting hair growth.

The device's simplicity and the minimally invasive nature of the treatment have contributed to its popularity in professional and at-home skincare routines.

What is microneedling for hair loss treatment? 

microneedling stimulate hair growth

Microneedling for hair loss treatment involves using a device, often a derma roller, equipped with fine needles to create tiny punctures on the scalp. This process is believed to stimulate hair follicles and improve the scalp blood vessels and circulation, potentially promoting hair growth and increasing the efficacy of topical hair growth treatments.

Elaborating on this, microneedling's principle for combating hair loss is based on its ability to initiate the body's natural healing process.

When the scalp is punctured with these fine needles, it triggers a wound-healing response that increases nutrient-rich blood flow and supply to the hair follicles, potentially revitalizing dormant ones and promoting new hair growth, including existing hair and beard hair growth.

Additionally, combining derma rolling with topical treatments enhances the absorption and effectiveness of these treatments applied to the scalp, thanks to the nutrient-rich blood flow.

The technique has gained popularity for skin and scalp care due to its minimally invasive nature, often seen as an alternative or complement to hair transplants.

How do derma rollers work and how do you use them?

Dermarollers create micro-injuries on the skin with tiny needles, triggering the body's natural healing process to increase collagen and elastin production. The device is rolled over the target area in horizontal and vertical lines, applying gentle pressure to ensure the needles penetrate the skin effectively, optimizing the stimulation of collagen production.

Here's a more detailed look at how derma rollers work and how to use them:

Mechanism of action for hair growth

The needles create micro-injuries on the scalp, stimulating the body's natural healing process.

This process can increase blood flow to the scalp, potentially rejuvenating hair follicles and promoting hair growth.

    Selecting the right needle size

    For hair growth, needles typically range from 0.5mm to 1.5mm. Longer needles can more effectively stimulate the scalp.


      Cleanse the scalp thoroughly to remove any product build-up and to prevent infection.

      Ensure the derma roller is disinfected before use.

        Using the derma roller on the scalp

        • Gently roll it across different sections of the scalp in horizontal, vertical, and diagonal directions.
        • Apply gentle pressure to ensure the needles effectively penetrate the scalp without causing unnecessary discomfort.
        • Focus on areas of concern where hair thinning or loss is most noticeable.

          Post-treatment care

          Applying a hair growth serum or treatment after derma rolling can be beneficial as the microchannels allow for deeper absorption.

          Clean the derma roller with an alcohol-based solution after each use.

            Frequency of use:

            For optimal results in hair count and quality, using the derma roller once every 3 to 4 weeks is recommended, allowing the scalp time to heal and benefit from stimulated collagen production.

              Expected benefits:

              It may improve hair density and thickness by stimulating hair follicle regeneration, an essential aspect of skin rejuvenation and hair transplants care.

              It can enhance the effectiveness of topical hair growth treatments due to better absorption.

                Does derma roll work for hair growth?

                Yes, derma rolling can be effective for hair growth. It creates micro-injuries on the scalp, stimulating the body's natural healing process, promoting hair follicle regeneration encourage hair growth, and increasing blood circulation, potentially leading to improved hair density and thickness.

                Research suggests that when combined with topical treatments like minoxidil, derma rolling can significantly enhance hair regrowth compared to topical treatments alone.

                The micro-injuries caused by the derma roller increase blood flow and nutrient delivery to the hair follicles, encouraging growth. 

                Additionally, these microchannels improve the absorption of topical treatments, making them more effective. While results can vary, consistent and proper use of a derma roller has been shown to offer promising outcomes for individuals experiencing hair thinning or loss.

                  • Repeat regularly: For best results, use the derma roller on your scalp once every 3 to 4 weeks, allowing the scalp to heal between sessions.

                    How do you choose the best derma roller for hair growth?

                    To choose the best derma roller for hair growth, consider needle length, quality, and durability. Ideally, a needle length of 0.5mm to 1.5mm is recommended for the scalp to effectively stimulate hair growth and follicles without causing unnecessary discomfort.

                    When selecting a derma roller for hair growth, the needle material is also crucial; titanium needles are durable and hypoallergenic, making them a preferred choice.

                    Look for a device with a sturdy handle for comfortable, secure grips during use. 

                    The roller should have a high needle count to ensure even coverage across the scalp. Choosing a product from a reputable brand is essential to ensure safety and efficacy.
