When it comes to combatting hair loss, numerous tools and treatments are available. One such tool is the derma roller, a handheld device covered in tiny needles. This device, when used correctly, can stimulate collagen and elastin production, boost blood flow, and help in rejuvenating the scalp and thickening the hair. However, not all derma rollers are created equal, with needle sizes varying significantly. This guide will explore what size derma roller is best for hair loss and how to use it effectively.

What Size Derma Roller for Hair Loss?

For those experiencing hair loss, derma rollers with needle sizes between 0.5 and 1.5 millimeters are typically recommended. A 0.5 mm derma roller can be used to tackle hair loss, while a 1.5 mm derma roller can stimulate hair growth more effectively. The 1.5 mm needle size is especially beneficial for scalp rolling, as it can better penetrate through hair and scalp buildup. Therefore, if you're looking for a hair-specific derma roller, consider those within this range for optimal results.

Understanding Derma Roller Sizes

Derma roller sizes are varied, ranging from 0.15 mm to 3.0 mm. The size of the needles on the roller is crucial in determining how the tool can be used. Smaller needle sizes, like 0.2 mm, are often used for enhancing product absorption and can be safely used at home. Larger needles, such as 1.5 mm, reach the hair bulge region, significantly boosting the production of endothelial growth factors for hair. These larger sizes are usually used for tackling hair loss and stimulating hair growth.

How Often to Use a Derma Roller for Hair Loss?

How often you should use a derma roller depends largely on the needle size. For derma rollers with a needle size of 0.15 - 0.5 mm, it is safe to use every 1-3 days. For needle sizes of 0.5 - 1.5 mm, it is recommended to use every 3-4 weeks. Always follow the instructions provided with your derma roller to ensure safe and effective use.
