What’s the Best Microneedling Size to Regrow Hair?

Microneedling (also called dermarolling) is a powerful and natural way to help regrow hair. It works by using tiny needles to gently poke the skin on your scalp. This helps wake up your hair follicles and makes it easier for hair to grow again.

When you combine microneedling with minoxidil (a hair regrowth treatment that’s FDA-approved), your results can be even better. Many studies show this combo works really well for people who have lost hair.

But here's a common question:
What needle size should I use for hair regrowth?

What Needle Length Is Best?

Experts say that using needles between 0.5 mm and 1.5 mm can help boost hair growth.

• Below 0.5 mm? That’s usually too short to wake up hair follicles.
• Above 1.5 mm? That might be too deep and can hurt or cause scars.

💡 Best size for hair regrowth? Most people get great results with a 1.0 mm dermaroller. This size helps reach the hair roots and boost blood flow, which encourages new hair to grow.

Is Microneedling Enough by Itself?

Not always. One study in the International Journal of Trichology found that people who used microneedling + minoxidil grew 4 times more hair than those who used minoxidil alone!

So, for the best results, use both together:
✅ A dermaroller with the right needle size
✅ A high-quality minoxidil solution

How to Get Started with Microneedling

If you’re new to dermarolling, start small and go slow.

• ✅ Begin with a 0.5 mm roller. Use it once a week to get used to it.
• ✅ As your skin adjusts, you can slowly move up to 1.0 mm, then 1.5 mm for better results.
• ✅ Always clean your roller and scalp before using it!

Over time, you can switch needle sizes depending on your hair goals and how your scalp responds.

Key Takeaways

• Use 0.5 mm to 1.5 mm needle length for hair regrowth.
• The 1.5 mm size is best for deep follicle stimulation.
• For best results, combine microneedling with minoxidil.
• Start slow, and increase needle size over time.
• Be consistent! Hair regrowth takes time and care.
