Thinning hair? We got you. Our new scalp derma roller has hundreds of tiny microneedles, which painlessly create tiny punctures in the skin stimulating scalp circulation and promoting a healthier scalp and skin. HOW TO USE: On dry hair gently roll over the scalp and hairline in the direction of the hair repeatedly 23 times using light pressure. For the best results, use alongside our Revolution Detoxifying Scalp Scrub, Soothe Me Tonic and Calm Me Scalp Smoothie. WARNING: Do not use on broken or irritated skin, active skin conditions or sensitive skin areas. If needles become damaged or bent, do not use. Sterilise derma roller before and after use.
