Derma Rollers & Microneedling for Hair Growth

Hair loss is a common concern that affects people of all ages, genders, and ethnicities. While various treatments have emerged to tackle this issue, microneedling and the use of derma rollers have gained significant attention for their promising results. Here, we delve into how this innovative technique may offer a new way to rejuvenate your locks.

What Is Microneedling and Derma Rolling?

Microneedling involves the use of a device fitted with fine needles that puncture the skin to induce collagen production and increase blood flow to the hair follicles. A derma roller is a handheld microneedling tool that is manually rolled over the scalp. Both aim to stimulate the body's natural healing processes to boost hair growth.

Mechanism of Action

The process begins by causing minor injuries to the skin, which triggers the body's healing response. This stimulates collagen production and increases blood flow to the hair follicles, thereby encouraging hair growth. Additionally, it increases the absorption of topical treatments like minoxidil, making them more effective.

Benefits for Hair Growth

Studies have shown that microneedling can significantly improve hair thickness and density. One such study demonstrated a 4-fold increase in hair count after microneedling treatment, in combination with minoxidil, compared to using minoxidil alone.

Risks and Side Effects

Microneedling is generally considered safe when performed by a trained professional. However, risks may include infection, scarring, and unwanted skin pigment changes. It is essential to consult with a healthcare provider to determine if this treatment is appropriate for you.

Practical Tips

Choose a derma roller with needle lengths between 0.5mm to 1.5mm for hair growth therapy and to improve absorption of topical solutions. Frequency can vary, but weekly sessions are commonly recommended for best results.


Microneedling and derma rolling have emerged as promising therapies in the battle against hair loss. Though more research is needed to establish long-term safety and effectiveness, these treatments offer a less invasive and relatively affordable option for those seeking to enhance their hair growth.
