Does Micro Needling Help Hair Growth?

Micro needling refers to a procedure that uses tiny needles to lightly puncture the skin, which is thought to help a variety of skin concerns, including improving wrinkles, acne scars, hyperpigmentation and, for some, may even stimulate hair growth. While this might sound a little intimidating, using a derma roller to create micro-injuries is believed to activate the body’s healing response, which in turn stimulates hair follicles.

The process encourages collagen production – a protein essential for healthy hair, skin, and nails. Just as Minoxidil improves blood circulation to the scalp to support hair growth, microneedling may increase blood flow and promote cell turnover in the treated areas.

Another proposed benefit is that microneedling enhances the absorption of Minoxidil. The microchannels created by the needles may allow the solution to penetrate deeper into the skin, amplifying its effectiveness.

In this article, we’ll look at some of the clinical studies to see if these claims are backed up by science.

Does It Actually Work?

Although research is still developing, current studies are encouraging.

• A 2013 clinical trial tested 5% Minoxidil alone versus Minoxidil combined with weekly microneedling. After 12 weeks, the combination group experienced faster and more noticeable regrowth.

• A 2018 study with 60 men found the same: those using both Minoxidil and microneedling had a significantly higher increase in hair count compared to the Minoxidil-only group. Researchers suggested microneedling may stimulate growth pathways that Finasteride and Minoxidil don’t directly target, such as activating stem cells and growth factors.

• Another trial looked at men who had seen little improvement from Finasteride and/or Minoxidil alone. After 15 microneedling sessions alongside their ongoing treatments, all participants showed new hair growth within 6 months. Three out of four men reported a 75% improvement, while one reported a 50% improvement.

While more research is needed, the existing evidence suggests that microneedling plus Minoxidil is more effective than either treatment on its own.

How to Use a Derma Roller with Minoxidil

Our derma roller is designed with fine 0.25mm needles, making it gentle enough for use every other day. To reduce the risk of infection, always disinfect the roller with isopropyl alcohol before and after each session.

Apply light pressure as you roll the device vertically and horizontally across thinning areas, passing over each section 4–6 times. It shouldn’t be painful – if it hurts, ease up on the pressure. Once finished, apply your Minoxidil as normal.

Because the needles become dull with time, you should replace your derma roller after about 3 months of regular use to keep it effective.

Most users experience no side effects when used correctly but stop if you notice irritation or inflammation. Avoid derma rolling altogether if you have sensitive skin or existing scalp conditions.

The Takeaway

Derma rolling is a straightforward way to potentially enhance the effectiveness of Minoxidil. By stimulating the scalp and improving absorption, it could help you see faster and better results in your hair regrowth journey.
