Sotrue derma roller is designed to improve blood flow to the scalp and promote hair growth. With 540 titanium needles measuring 0.5mm, it's an effective tool for enhancing the absorption of hair growth oils and serums. The derma roller has an ergonomic handle that ensures comfortable use. Its lightweight and easy-to-use design allows effective treatment of targeted areas. Its handle design allows for easy control and manoeuvring of the device, while the 0.5mm needle length makes it suitable for all hair types. The derma roller is suitable for improving the health of the skin but also for promoting hair growth. It can help distribute nutrients to hair follicles and improve the effectiveness of hair growth products. The derma roller creates tiny punctures in the skin or scalp, stimulating the body's natural healing process. This process increases blood flow to the treated area and helps enhance the absorption of hair and skin products. It's important to sterilise the derma roller after every use to prevent the spread of bacteria and ensure its effectiveness. A simple sanitisation routine involves washing the roller head with soap and warm water and then sterilising it with an alcohol solution or sanitiser.
