Can Dermarolling Actually Stimulate Hair Growth? | As Seen in NBC Select

Dermarolling, or microneedling, is a popular skincare treatment that boosts collagen production and enhances product absorption. While it’s commonly used on the face, some people are now using it on their scalps to encourage hair growth. Learn more in NBC Select’s article and hear Dr. Alexandra Bowles’ opinion on the technique.

What is the process of dermarolling?

Dermarolling involves using a small handheld device covered with tiny needles. The roller is gently rolled over the skin to create controlled micro-injuries. This process stimulates the skin’s natural healing response, encouraging collagen production and cell turnover. Depending on the needle length, you can use dermarolling on the face, scalp, or body to address various skin concerns.

How does dermarolling benefit your face?

I don’t recommend dermarolling the face at home. I prefer to recommend that a trained medical professional perform microneedling. People can do more harm than good with overused or dirty dermarolling devices on the face. My biggest concern is scarring or infection so while I think it is great for improving scalp circulation, I would hold off on the face!

Why might someone want to use a dermaroller on their scalp? 

Using a dermaroller on the scalp can help promote hair growth. The micro-injuries created by the roller stimulate the scalp and increase blood circulation to hair follicles, encouraging them to stay healthy and active. It can also help with conditions like thinning hair or hair loss, as it encourages the absorption of hair-growth serums or oils, improving their effectiveness.

If you want to dermaroll your scalp, how should you do it?

If you’re considering dermarolling your scalp, start by choosing the right needle length—usually, a 0.25mm to 0.5mm needle is best for the scalp. Before you begin, make sure your scalp is clean, and the dermaroller is sanitized to avoid any infection. Gently roll the dermaroller across the scalp in different directions—vertical, horizontal, and diagonal—to target all areas. Afterward, you can apply a hair growth serum or oil to nourish the scalp. Always be gentle and avoid pressing too hard, as this can cause damage to your skin.

Are there any risks of dermarolling your scalp?

The primary risk of dermarolling the scalp comes from infection, which can occur if you don’t properly sanitize the roller or if you damage the skin. Overdoing it or applying too much pressure can also cause irritation or damage to the scalp, leading to hair breakage. It’s important to be gentle and follow the correct steps, and if you have any concerns, it’s always a good idea to check with your dermatologist before starting.

Is there anyone who should avoid dermarolling your scalp?

Those with active scalp conditions, such as psoriasis, eczema, or an open scalp wound, should definitely avoid dermarolling. It can increase irritation and lead to further complications. If you’re dealing with hair loss from a medical condition, it’s important to speak with your doctor before using a dermaroller to ensure it’s appropriate for your situation.

What are some other ways to encourage hair growth?

In addition to dermarolling, there are several other methods you can try to encourage hair growth. Using topical treatments like minoxidil, a well-known hair growth serum, can be effective. Eating a balanced diet rich in vitamins and minerals, particularly biotin, vitamin D, and iron, can also support healthy hair growth. Regular scalp massages to increase circulation, as well as minimizing stress, can also help maintain healthy hair.
