Derma rolling can be an effective method of increasing hair growth. However, the scalp must be clean and healthy for this method to work efficiently.
Needle Size
The needle size of a derma roller is critical to its efficiency; too long needles can damage hair follicles, and it is also possible to injure yourself with improper usage or cleaning. Therefore, before and after each use, you should sanitize the roller with antimicrobial solutions to ensure optimal use.
Microneedling with 0.25mm needles is ideal for scalp microneedling as it will not cause irritation or damage to hair follicles. To determine the perfect needle length for you and your scalp needs, it’s wise to consult a dermatologist.
Material
Material selection is integral to how effectively derma rollers for hair loss work. A derma roller is a small metal tool with microneedles to prick the skin. Some models made of titanium have become popular due to their durability and resistance to corrosion; however, this material may prove costly if multiple treatments are required regularly.
Safety
Derma rollers puncture the surface of your scalp to activate dermal papillae – this area controls how many hair follicles develop and how much hair each one produces – stimulating hair growth and activating dermal papillae to facilitate new hair follicle growth. When selecting a safe derma roller for hair loss, it must specifically cater to this use case.
Ideally, the ideal derma roller for hair loss should be easy to maintain and clean, since its use involves micro-punctures in your skin that could potentially become infected if not done so regularly. Furthermore, its needles must be sterilized before use to function effectively.
Cost
Dermarollers may be most famously associated with skin health benefits, but they also encourage hair growth. Dermarollers stimulate the scalp and promote new hair growth by improving blood circulation to the area; additionally, they can enhance the absorption of topical hair growth products like minoxidil.
Dermarollers are generally safe to use, though proper usage is critical for minimizing risk and increasing effectiveness. Follow all instructions the manufacturer provides when using your roller and ensure that it remains clean between uses to reduce infection risk and ensure maximum treatment efficacy.
A good derma roller for hair loss should be small with precise needles that penetrate the scalp without causing pain or irritation, with an easy rolling surface. You could also opt for a derma stamp – similar to a roller but allowing more pinpoint targeting and less likely to trap or pull hair strands than its counterparts.
