Micro-Roller: Derma Roller for Hair Growth
This article was medically reviewed by Dr. Kuddusi Onay
Derma rolling, also known as micro-rolling, is a popular technique used to promote hair growth.
The process involves using a device called a derma roller, which is a handheld roller with tiny needles that gently puncture the scalp.
This procedure stimulates blood circulation, encourages the production of collagen, and enhances the absorption of hair growth products. As a result, it can be an effective tool for those experiencing hair thinning or seeking to improve hair density.

How Micro-Rollers Stimulate Hair Follicles?
The micro-roller works by creating tiny micro-injuries on the scalp’s surface. These micro-injuries trigger the body’s natural healing response, which includes increased blood flow to the affected area. The enhanced blood circulation brings essential nutrients and oxygen to the hair follicles, promoting healthier and stronger hair growth. Additionally, the micro-needling process stimulates the production of collagen and other growth factors that are crucial for hair regeneration.
Step-by-Step Guide to Using a Micro-Roller for Hair Growth
Using a micro-roller for hair growth is a straightforward process, but it requires proper technique and hygiene to ensure safety and effectiveness. Here is a step-by-step guide:
- Clean Your Scalp: Begin with a clean scalp by washing your hair with a mild shampoo.
- Disinfect the Roller: Sterilize the derma roller with rubbing alcohol to prevent any infections.
- Section Your Hair: Divide your hair into manageable sections to ensure even coverage.
- Roll the Scalp: Gently roll the micro-roller over the scalp in different directions (vertical, horizontal, and diagonal) for about 5-10 minutes. Avoid applying excessive pressure.
- Apply Hair Growth Serum: After rolling, apply a hair growth serum to enhance absorption and effectiveness.
- Clean the Roller: After use, disinfect the roller again and store it in a clean, dry place.
Benefits of Micro-Rolling for Hair Health and Thickness
Micro-rolling offers several benefits for hair health and thickness, including:
- Improved Blood Circulation: Enhances nutrient delivery to hair follicles.
- Increased Collagen Production: Strengthens hair structure and promotes growth.
- Enhanced Product Absorption: Increases the efficacy of topical hair treatments.
- Scalp Health: Helps remove dead skin cells and stimulates cell turnover.
Micro-Roller vs. Other Hair Growth Treatments: A Comparison
When comparing micro-rolling to other hair growth treatments, it’s important to consider factors such as effectiveness, cost, and potential side effects:
- Minoxidil: A common topical treatment that can be used in conjunction with micro-rolling for better results.
- Hair Transplants: A more invasive and expensive option with immediate results, suitable for advanced hair loss.
- Laser Therapy: Non-invasive but can be costly and time-consuming.
- Natural Remedies: Often less effective and lack scientific backing compared to micro-rolling.
Safety Tips and Best Practices for Using a Micro-Roller
To ensure safe and effective use of a micro-roller, follow these best practices:
- Avoid Over-Rolling: Limit usage to once or twice a week to prevent scalp irritation.
- Use the Right Needle Size: For hair growth, 0.5mm to 1.5mm needles are recommended.
- Maintain Hygiene: Always sterilize the roller before and after use.
- Be Gentle: Do not apply too much pressure while rolling.
- Consult a Professional: If you have a scalp condition or are unsure about using a micro-roller, seek advice from a dermatologist or trichologist.
It is recommended to use a micro-roller for hair growth once or twice a week. Overusing the device can cause scalp irritation and damage. Consistent, moderate use is key to achieving optimal results without harming the scalp.
Yes, you can use a micro-roller in conjunction with other hair growth treatments such as minoxidil or hair growth serums. The micro-needling process enhances the absorption of topical treatments, potentially increasing their effectiveness. Always follow the instructions for each product and consult with a healthcare professional if you have any concerns.
Mild redness and slight irritation are common after using a micro-roller, as the needles create tiny micro-injuries on the scalp. These symptoms usually subside within a few hours. If you experience severe irritation, prolonged redness, or any signs of infection, discontinue use and seek medical advice.
For hair growth, needle sizes between 0.5mm and 1.5mm are generally recommended. The 0.5mm needles are suitable for beginners and those with sensitive scalps, while the 1.0mm to 1.5mm needles can be used for more intensive treatments. It’s important to start with a smaller needle size and gradually increase if necessary. Always ensure you are comfortable with the process and consult a professional if unsure.
