How to Use Dermaroller for Hair Loss: Complete Guide to Reactivate Hair Growth

For over 30 years, microneedling therapy has helped millions of people around the world achieving sustainable hair growth. But how to use dermaroller for hair loss plays a substantial role in achieving these long-term results.

Below, Dr. Sekran Aygin Clinic’s team dwells into what dermarolling exactly is, how it is applied, and how to achieve the most noticeable transformation.

What is a Dermaroller?

A dermaroller is a device which consists of hundreds of microneedles. When rolled over the scalp, these microneedles create tiny micro-injuries which trigger the body’s natural healing process. Dermaroller for hair growth works by increasing blood flow and promoting new cell growth.

In medical terms, micro-injuries stimulate collagen production. When used on the scalp, a dermaroller can be a game-changer against hair loss and thinning. It helps reactivate dormant hair follicles and makes hair growth products like minoxidil, peptides, or natural oils, much more effective.

How Does a Dermaroller Work for Hair Loss?

Dermarolling for hair growth is a type of microneedling therapy. This method has been widely studied to regenerate tissue and improve follicular health. When used correctly, a dermaroller can:

✅ Increase blood flow to the scalp, delivering oxygen and nutrients to hair follicles.
✅ Boost collagen production, strengthening hair follicles and improving scalp health.
✅ Enhance product absorption, making treatments like minoxidil, rosemary oil, or caffeine-based serums more effective.
✅ Reduce dermatitis or inflammation, which is often a factor in alopecia.

Studies have shown that microneedling—when combined with hair growth treatments—can lead to significantly better results compared to using hair growth products alone.

How to Use Dermaroller for Hair Growth

You’re wondering how to use a dermaroller for hair loss, and you’re right. Proper technique and frequency are key to:

• Achieve noticeable hair regrowth 
• Avoid potential side effects.

Below, you’ll find a step-by-step guide, followed by a section on how to combine dermarolling with hair growth products for maximum results.

1.     Preparing Your Scalp Before Dermarolling

To minimize the risk of irritation or infection, proper scalp hygiene is essential before using a dermaroller.

1. Wash your hairwith a gentle, sulfate-free hair shampoo to remove oil, dirt, and product buildup.
2. Dry your hair and scalp completelybefore using the dermaroller. Wet skin is more sensitive and prone to irritation.
3. Sanitize your dermarollerby soaking it in 70% isopropyl alcohol for 5-10 minutes. This kills bacteria and prevents infections.
4. Disinfect your handsto avoid transferring bacteria to your scalp.

2.     How to Apply the Dermaroller on the Scalp

When using a dermaroller for hair growth, technique matters. Here is how to maximize scalp stimulation without over-irritation:

1. Start at the front hairlineand roll the dermaroller backwards toward the crown.
2. Divide your scalp into sections (e.g.,left side, right side, back, crown) and roll each section separately.
3. Rollin four different directions:

• Vertically (front to back)
• Horizontally (side to side)
• Diagonally (left to right)
• Diagonally (right to left)

4. Applygentle pressure—enough to feel slight discomfort but not pain. Do not press too hard, as this can cause unnecessary trauma.
5. Roll each area5-10 times before moving to the next section.

3.     How Often Should You Use a Dermaroller for Hair Growth?

The frequency of dermarolling for hair growth depends on the needle size (see below for detailed info):

⚠️ Avoid overusing the dermaroller. Your scalp needs time to heal and regenerate new cells. Using it too often can lead to inflammation and potential hair follicle damage.

4.     Aftercare Matters

After rolling, your scalp is in a highly absorbent state, making post-treatment care critical for preventing irritation and maximizing hair growth.

✅ What to Do After Dermarolling:

✔️ Sanitize your dermaroller by soaking it in 70% isopropyl alcohol for 5-10 minutes.
✔️ Avoid touching your scalp with dirty hands for at least a few hours.
✔️ Wait at least 24 hours before applying harsh hair products like shampoo, conditioner, or styling gels.
✔️ Use a clean pillowcase to prevent bacteria from irritating your scalp overnight.

❌ What to Avoid After Dermarolling:

🚫 Alcohol-Based Products → Can cause severe dryness and irritation.
🚫 Harsh Shampoos (Sulfates & Parabens) → Can strip the scalp and delay healing.
🚫 High-Dose Retinol or Acids (AHA/BHA) → Can make the scalp overly sensitive.
🚫 Excessive Heat (Hair Dryers, Saunas, Sun Exposure) → Can worsen irritation.

Where Can Dermarolling Be Applied?

Bear in mind, Dermarolling isn’t just for hair loss—it’s a versatile treatment that can be applied to different areas of the body to address various skin and hair concerns.

• Scalp: The scalp is one of the most popular areas for dermarolling because it stimulates hair growth.
• Face: Dermarolling is widely used in skincare for its ability to boost collagen production, reduce fine lines, and improve skin texture.
• Beard: Just like on the scalp, dermarolling the beard area stimulates thicker growth.
• Stretch Marks & Cellulite: Dermarolling is one of the few at-home treatments that can improve the appearance of stretch marks and cellulite.

Benefits & Limitations

As we have seen, dermarolling for hair loss displays a wide array of beneficial effects, which include 3 main advantages:

✔ Stimulates Hair Growth 
✔ Boosts Collagen Production 
✔ Cost-Effective & Non-Invasive 

However, dermarolling also has limitations that should be closely considered:

❌ Results Take Time – and require use over months.
❌ It has potential Side Effects – with improper technique or excessive rolling.
❌ It’s not Effective for Severe Baldness – completely bald areas might require a hair transplant.

Dermarolling Before & After

Dermarolling for hair growth takes time, but consistent use yields visible improvements.

• Week 1-2: Mild redness, tingling, and slight shedding (a normal part of the renewal process).
• Month 1-2: Increased scalp circulation, slight thickening of existing hair, and improved skin texture.
• Month 3-4: Noticeable reduction in hair shedding, new baby hairs appear, skin looks smoother and firmer.
• Month 5-6: Significant improvement in hair density, stronger strands, and reduced bald patches.

Dermaroller & Hair Growth Products to Achieve the Best Results

The micro-injuries created by the dermaroller allow active ingredients to penetrate deeper into the scalp, making treatments like minoxidil, natural oils, and peptides significantly more effective.

However, not all hair growth products are safe. Below, we’ll cover how to apply the best treatments correctly, and what to avoid.

1.     Minoxidil (Rogaine) – The Medical Alternative

Minoxidil is one of the most studied and FDA-approved treatments for androgenetic alopecia (male and female pattern baldness).

How to Use It with a Dermaroller:

✔️ Wait at least 12-24 hours after rolling
✔️ Apply 1 ml of minoxidil solution directly to the scalp and gently massage it in.
✔️ Use twice daily (morning & night) on non-dermarolling days.

⚠️ Important Warning:

• Do NOT apply minoxidil immediately after dermarolling if you’re using a 1.0 mm or longer needle. It may cause severe irritation, burning, and excessive absorption.

2.     Rosemary Oil – The Natural Alternative

Studies show that rosemary oil is as effective as minoxidil in promoting hair growth but with fewer side effects.

How to Use It with a Dermaroller:

✔️ Wait 6-12 hours after dermarolling before applying rosemary oil.
✔️ Mix a few drops of pure rosemary oil with a carrier oil (e.g., jojoba or castor oil) and massage into the scalp.
✔️ Use daily or at least 3-4 times a week for best results.

3.     Caffeine-Based Serums

Caffeine is a DHT blocker that stimulates blood flow to hair follicles, prolonging the growth phase and reducing hair thinning.

How to Use It with a Dermaroller:

✔️ Apply immediately after dermarolling 
✔️ Gently massage a few drops of caffeine serum into the scalp.
✔️ Use once daily, preferably in the morning.

4.     Peptide-Based Serums (Copper Peptides & Redensyl)

Peptides like copper peptides, Redensyl, and Procapil are cutting-edge ingredients that:

✅ Stimulate stem cells in hair follicles for regrowth.
✅ Increase blood circulation and provide nutrients for stronger hair.
✅ Reduce scalp inflammation, helping hair grow in a healthy environment.

How to Use Them with a Dermaroller:

✔️ Apply immediately after rolling—peptides are safe and non-irritating.
✔️ Use once daily (morning or night).
✔️ Best used in combination with minoxidil or natural oils for enhanced effects.

⚠️ Avoid synthetic peptides that contain harsh preservatives, as they can cause scalp irritation.

How to Choose the Best Dermaroller Size

The size of the microneedles is one of the most critical factors when selecting a device for scalp use.

🔹 Needle Length:

• 0.5 mm → Best for beginners, the safest, easiest-to-use option.
• 1.0 mm → Stimulates hair follicles more effectively, suitable for moderate hair thinning.
• 1.5 mm → Deep stimulation for significant hair loss, should be used cautiously (once a week or less).

⚠️ Avoid dermarollers with needles longer than 1.5 mm for at-home use. They can cause damage if not employed by a dermatologist.

🔹 Needle Material:

• Titanium needles → More durable, but slightly less effective.
• Stainless steel needles → Less durable but extremely hygienic and sharp.

🔹 Needle Density:

• Fewer needles (192-540 needles) → Penetrate deeper and cause less scalp trauma.
• More needles (1000+ needles) → Cover more area but may not be as effective for deeper stimulation.
