Microneedling has become an increasingly popular method for encouraging hair regrowth. This technique uses tools like dermarollers, derma stamps, and microneedling pens to create tiny punctures in the scalp, stimulating a natural healing response. In this guide, we’ll explain how microneedling for hair growth works, help you choose the right tools, and provide a step-by-step process.
Why Microneedling Works for Hair Growth
Microneedling can help with hair growth by making tiny, controlled “micro-injuries” on the scalp. These tiny punctures send signals to your body to heal the area, which boosts blood flow and collagen production. Both are important because blood brings nutrients to the hair roots, and collagen helps keep hair strong.
Microneedling also creates small channels in the scalp, which allows treatments like minoxidil to get deeper into the skin, making them more effective than when applied to the surface alone. This combination of increased blood flow, collagen, and better product absorption can create the ideal conditions for hair to grow thicker and stronger over time.
Choosing the Right Microneedling Tool
- Derma Roller: Ideal for beginners and for covering larger areas of the scalp. Recommended model: Derma Roller G4.
- Derma Stamp: Suited for smaller, targeted areas or sensitive skin, allowing precise application. Recommended model: DRS 140A.
- Microneedling Pen: The most versatile option, offering adjustable needle depth and speed, with replaceable cartridges for each use, making it both powerful and hygienic. Recommended model: Dr. Pen M8, Dr. Pen M8S.
Selecting Needle Depth and Pin Count
- Needle Depth: Choose a depth based on your scalp’s thickness and sensitivity. Start with 0.3 - 0.5 mm for general scalp treatments to gauge your scalp’s reaction. If your scalp handles this depth well, you can gradually increase to 0.5 - 1 mm for deeper stimulation. Always monitor how your scalp responds whenever you increase the depth to avoid any potential side effects.
- Pin Count: Choosing the right pin count depends on the area you're treating and your goals. For smaller, targeted spots, use 12 or 16-pin cartridges; they penetrate deeper, giving focused stimulation (but may feel more intense). For larger or sensitive areas, go with 36 or 42-pin cartridges for faster, even coverage with a gentler touch across the scalp.
How often do you use it?
Start with one session per week to see how your scalp reacts. If it responds well, you can increase to a maximum of twice a week, but avoid going beyond that to prevent irritation.
How to Use Microneedling for Hair Growth
-
Cleanse Your Scalp
Wash with a gentle shampoo to remove any dirt or oils. Ensure the scalp is dry before starting. -
Disinfect the Device
Clean the microneedling tool with alcohol and allow it to air dry. -
Microneedle the Scalp
Divide hair into sections, then gently roll or press the device over the scalp in vertical, horizontal, and diagonal motions. Skip microneedling if you have open sores or scalp issues, as it can worsen irritation. -
Apply a Scalp Serum (Optional)
After microneedling, wait a few hours before applying a calming serum. Active serums like minoxidil are best applied the next day. -
Disinfect the Device After Use
We recommend not reusing microneedling needles to ensure safety and hygiene, as they directly penetrate the skin. For tools like rollers, make sure to thoroughly clean them with alcohol, rinse well, and store them safely after each use.
Patience Is Key
Visible hair growth results take time. Some may notice initial improvements within a month, but typically it takes 3-6 months for significant changes. For optimal results, complete 4-6 sessions as a cycle and assess the impact after 2-3 cycles. If you have any concerns about your scalp's reaction or want personalized advice, consider consulting a doctor or dermatologist to ensure microneedling is right for you.
