What is A Dermaroller?
A hair loss dermaroller is a simple device. That creates tiny pinpricks on the surface of the skin. The pricks penetrate into the dermal layer. Just deep enough to stimulate the production of new cells and boost circulation. Although, without causing damage. The process is also known as micro-needling. The derma roller has been used as a beauty device for decades. Helping to renew the youthfulness of skin. The process works by stimulating the production of collagen. As a result reducing the appearance of wrinkles. Micro-needling first gained its reputation as a scar treatment during the 1990s. Since then, it’s been studied as a potential alternative for thinning hair. Being an alternative treatment for hereditary hair loss.
Aside from collagen production in the skin, it’s thought that micro-needling can also help induce stem cells in the scalp that lead to hair growth.
Micro-needling may also promote the absorption of hair growth products, such as minoxidil (Rogaine). Another study explored the potential benefits of micro-needling when used with corticosteroids to reduce hair follicle inflammation from alopecia areata.
How Does the Dermaroller Help With Thinning Hair?
In a similar way that the hair loss dermaroller is used to stimulate collagen production on the facial skin, it can also be used to increase cell production and increase blood circulation around the scalp, which in turn will help with new hair growth.

- Allows the scalp mixture to penetrate deeper into the scalp making it more effective.
How it works
During micro-needling, your practitioner may use several needles, ranging between 0.25 and 3 millimetres long. They’re all contained in a handheld device. Also called a roller, the device is rolled along the treatment area, creating small injuries. Unlike other treatments that target your skin’s surface, the needles used in the rollers extend to the middle layer of skin. As these micro injuries heal, your skin produces more collagen and fibres. It also helps to strengthen the hair follicles.
The actual procedure time can vary based on the treatment area but may take as little as 30 minutes.
Side effects of micro-needling on the head
Micro-needling itself can cause bruises, oozing from the wounds, and skin irritation. There’s also a risk that the wounds caused by the needles may scar.
The area may be red and inflamed for a few days following the procedure. most side effects diminish within five days after your treatment.
Micro-needling also isn’t recommended for people who are pregnant.

Your scalp may be more sensitive to the sun after treatment. Wearing sunscreen every day is recommended. A hat can also help protect your scalp when outdoors.
Another risk of micro-needling on your head is the possibility of infection. While the needles are small, they’re still inflicting wounds.

You may be at an increased risk for infection if you’re in poor overall health, or if you have a history of frequent infections.
