What is a derma roller?
A derma roller is a handheld tool which uses small needles (typically between 0.2-1.5m) to create tiny punctures in the skin of the scalp. It is a micro-needling tool and evidence suggests that using it along with Minoxidil may be more effective than using Minoxidil alone.
While it might sound unusual, these micro-abrasions are thought to stimulate the hair follicle by triggering the body’s natural healing process.
This promotes the production of collagen, an important protein crucial for healthy hair, skin, and nails. Much like how Minoxidil works to halt hair loss and promote hair growth by improving blood flow to the scalp, the tiny tears are thought to increase blood circulation to the scalp and encourage cell turnover as they heal.
Derma rolling is also believed to improve the absorption of Minoxidil solution, by allowing it to penetrate the scalp skin more easily through the micropores created by the tiny puncture wounds, boosting the benefits of Minoxidil.
How to use a derma roller and Minoxidil for best results:
Sons derma roller uses a fine 0.25mm needle, which is gentle enough to be used every other day. Using mild pressure, you should roll the device vertically and horizontally over your scalp 4-6 times, focusing mainly on the areas that are thinning the most. If it hurts, you might be pressing too hard.
Afterwards, you can apply your topical minoxidil (used for androgenetic alopecia) as usual. When used as directed side effects are unlikely but stop using the roller if you notice any irritation or inflammation. Also, avoid derma rolling if you have sensitive skin or any scalp conditions.
You should always clean your derma roller before and after each use, with an alcohol-based cleaner like isopropyl alcohol, to avoid the risk of infection. Sons recommend replacing your derma roller after 3 months of regular usage, as the needles blunt over time and become less effective.
