Mars by GHC Derma Roller 0.5 mm for hair regrowth can help you get healthier hair in many ways, and with some regular use, you will definitely enjoy the benefits.

The derma roller is a very simple yet powerful skin rejuvenation tool. It is based on the concept of micro-needling. These devices use needles that are much finer than human hair, so they do not cause pain as normal needles would, while still getting the same benefits.

• Derma rollers are small, handheld devices made with a small roller with hundreds of tiny needles attached to the surface. When rolled over the scalp, they act similarly to dermaplaning. The needles gently prick the skin, creating tiny holes that allow collagen and elastin production on your scalp.  
• Regular treatment with a derma roller for hair may make your hair thicker and also shinier. Derma roller for hair growth helps reduce hair loss and also gives hair a healthier look and feel by giving it more volume, which means you won't have to worry about your thinning hair anymore.

Sterilize the roller with hot water or alcohol before and after treatment. Gently roll horizontally, vertically, and diagonally on the treatment area about 4-5 times. Apply hair vitalizer for better absorption.
