Our Hair Thickening serum contains tocopherol (vitamin E), ginger root extract, and rosemary leaf oil. It can improve overall shine and improve blood circulation on the scalp. Its application method is simple: after cleaning and conditioning, open the package, remove the patch, tear off the film on the back, and apply the patch to the skin under the eye for about 5-15 minutes. After removing the patch, gently massage it with your fingertips to make it absorb better. And can stimulate hair regrowth in bald spots.
