What is a Derma Roller?

A derma roller, also known as a microneedle roller, is a handheld device with hundreds of tiny needles on its surface.(1)

These needles create micro-injuries when rolled over the skin, which stimulate the body's natural healing response.

When used on the scalp, a derma roller can promote blood circulation and collagen production, leading to healthier hair follicles and potential hair growth.

How Does a Derma Roller Work?

When you use a derma roller on your scalp, the tiny needles gently puncture the skin's surface.

This process activates the body's natural healing mechanisms, triggering an increase in blood flow, collagen production, and cell turnover.

These effects can potentially rejuvenate hair follicles and promote hair growth.

What Are the Benefits of Using a Derma Roller?

Using a derma roller for hair growth offers a range of benefits that can contribute to the overall health and appearance of your scalp.(2)

Let's delve deeper into the benefits of using a derma roller:

Increased Blood Circulation

When you roll a derma roller over your scalp, the tiny needles create micro-injuries, which trigger an increase in blood flow to the treated area.(3)

Improved blood circulation means that more oxygen, nutrients, and growth factors are delivered to the hair follicles.

This can promote a healthier scalp environment and provide the necessary nourishment for optimal hair growth.

Enhanced Absorption of Topical Products

The micro-channels created by the derma roller on the scalp allow for better absorption of hair growth serums, oils, or other topical treatments.

The increased permeability of the skin allows these products to penetrate deeper into the scalp, reaching the hair follicles directly.

This synergistic approach enhances the effectiveness of the applied products, maximizing their benefits for hair growth.

Stimulated Collagen Production

Collagen is a vital protein that provides structure and support to various tissues in the body, including the scalp.

When you use a derma roller, the micro-injuries stimulate the production of collagen in the scalp.

The increased collagen levels can strengthen the hair follicles, improving their ability to anchor the hair strands and potentially reducing hair loss.

Reduced Hair Thinning

Hair thinning is a common concern for both men and women.

Using a derma roller can help address this issue by promoting hair follicle health and stimulating new hair growth.

By increasing blood circulation and collagen production, the derma roller may contribute to thicker, fuller hair, reducing the appearance of thinning areas on the scalp.

Improved Scalp Health

A healthy scalp is the foundation for healthy hair growth.

The micro-injuries created by the derma roller can encourage the shedding of dead skin cells, excess oil, and debris that may clog hair follicles.

This exfoliation effect helps maintain a clean and balanced scalp environment, reducing the risk of dandruff, itchiness, and scalp conditions that can hinder hair growth.

Non-Invasive and Cost-Effective

Compared to more invasive procedures like hair transplants or laser therapies, using a derma roller is a non-invasive and cost-effective alternative.

It allows you to take control of your hair care routine from the comfort of your own home.

With proper technique and regular use, a derma roller can potentially yield significant improvements in hair growth without the need for expensive treatments.

Versatile and Targeted Treatment

Derma rollers come in various needle lengths, allowing you to choose the most suitable option for your specific needs.

Whether you're targeting specific problem areas, addressing hair loss, or seeking overall scalp health, derma rollers provide a versatile tool for customized treatments.

The ability to adapt the needle length according to your scalp's sensitivity and the severity of your hair concerns makes the derma roller a versatile solution.

How to Use a Derma Roller?

Using a derma roller correctly is crucial for achieving optimal results. Follow these steps to use a derma roller effectively:

  1. Cleanse your scalp: Start by thoroughly washing your scalp to remove any dirt, oils, or product buildup.

  2. Disinfect the derma roller: Using rubbing alcohol, sanitize the derma roller before each use to minimize the risk of infection.

  3. Section your hair: Divide your hair into manageable sections to ensure even coverage and easy maneuverability.

  4. Gently roll the derma roller: Starting from the front hairline, roll the derma roller vertically, horizontally, and diagonally across each section of your scalp. Apply gentle pressure without causing discomfort or pain.

  5. Change direction and repeat: After completing one section, change the direction of rolling and repeat the process until you have covered your entire scalp.

  6. Apply hair growth serum: Immediately after using the derma roller, apply a hair growth serum or any other topical treatment recommended by your dermatologist.
    The micro-channels created by the derma roller enhance the absorption of the product.
  7. Clean and store the derma roller: Rinse the derma roller with warm water and mild soap to remove any debris. Disinfect it again with rubbing alcohol, and store it in a clean and dry place.

The Different Types of Derma Rollers

Derma rollers come in various types, mainly differing in needle length.

The needle size you choose depends on your specific skin concerns.

Here are the common types of derma rollers:

  • 1.0.2mm - 0.3mm: These derma rollers have short needles and are suitable for enhancing product absorption and maintaining scalp health.

  • 2.0.5mm - 1.0mm: Ideal for stimulating hair growth, these derma rollers penetrate the skin more deeply, promoting collagen production and blood circulation.

  • 3.1.5mm - 2.0mm: These longer needles are generally used by professionals for advanced treatments and should only be used under expert guidance.

Safety Tips and Precautions for Using a Derma Roller

To ensure a safe and effective derma roller experience, consider the following tips:

  • Do not share your derma roller: Using someone else's derma roller can increase the risk of infections and other complications.

  • Avoid using on irritated or infected scalp: If you have any scalp conditions or wounds, it's best to avoid using a derma roller until they heal completely.

  • Be gentle: Apply light pressure when rolling the derma roller to avoid skin irritation or injury.

  • Clean and disinfect: Clean the derma roller before and after each use to maintain hygiene and prevent infections.

  • Follow a consistent schedule: Consistency is key.
    Use the derma roller once or twice a week, as recommended by your dermatologist or hair care professional.

  • Replace the derma roller: Over time, the needles on the derma roller can become dull.
    Replace your derma roller every few months or as recommended by the manufacturer.

How Often Should You Use a Derma Roller?

The frequency of derma roller usage depends on your specific needs and skin sensitivity. As a general guideline:

For beginners

Start with once a week and monitor your scalp's response. Gradually increase the frequency if your scalp tolerates it well.

For experienced users

You can use the derma roller up to twice a week, depending on your scalp's condition and the advice of your dermatologist.

Post-Treatment Care and Recovery

After using a derma roller, it's essential to follow proper post-treatment care to optimize the results and minimize any potential side effects. Here are some guidelines:

Avoid direct sun exposure

Protect your scalp from the sun for at least 24 to 48 hours after using a derma roller.

Moisturize your scalp

Apply a hydrating scalp serum or moisturizer to nourish and soothe the treated area.

Avoid harsh hair products

For a few days post-treatment, avoid using hair products that contain harsh chemicals or irritants.

Patience is key

Results from derma roller treatments may take time.

Consistency and patience are vital for achieving the desired outcome.

Common Mistakes to Avoid When Using a Derma Roller

To make the most of your derma roller sessions, steer clear of these common mistakes:

Pressing too hard

Applying excessive pressure can cause skin damage and discomfort.

Remember, gentle and controlled movements are key.

Using a dirty derma roller

Failing to clean and disinfect your derma roller can introduce bacteria to your scalp, leading to infections.

Sharing your derma roller

Each derma roller is intended for personal use. Sharing it increases the risk of cross-contamination and infections.

Using the wrong needle size

Selecting the wrong needle length for your specific needs can lead to ineffective results or skin damage.

Choose wisely based on your dermatologist's advice.

Can I Use a Derma Roller Without Serum?

While using a hair growth serum or other topical treatments with a derma roller can enhance results, it is still possible to use a derma roller without a serum.

The derma roller's micro-injuries alone can stimulate blood flow and collagen production in the scalp.

However, using a serum specifically formulated for hair growth can maximize the benefits and nourish the scalp.

How Do I Know If My Derma Roller Is Working?

Assessing the effectiveness of a derma roller can take time, as individual results may vary. Here are some signs that indicate your derma roller is working:

  • Mild redness: After using a derma roller, you may experience slight redness, which is a normal response to the treatment.

  • Improved scalp health: Over time, you may notice a healthier scalp, reduced hair thinning, and potentially new hair growth.

  • Enhanced product absorption: If you're using a hair growth serum or other topical treatments, you may observe improved absorption and effectiveness.
