Minoxidil tincture is usually used about 1 month after hair transplantation. Minoxidil tincture is a common clinical medication used to treat and prevent hair loss. After hair transplantation, the transplanted hair follicles usually appear red and swollen, but do not scratch with your hands to avoid infection that may affect the survival rate of the hair follicles. Most of the hair follicles have survived after one month, and the use of Minoxidil tincture can promote the dilatation of small arteries, which is conducive to the absorption of sufficient nutrients by the hair follicles, and is conducive to hair follicle survival. In addition, after hair transplantation, you also need to develop good habits, eat a light diet, work and rest regularly, but also pay attention to personal hygiene to avoid infection.
