Minoxidil refers to the tincture of minoxidil, which is used for about six months to a year and a half after a hair transplant. Hair transplantation involves taking hair follicles from the patient’s posterior occipital region as a source of hair, separating them into single or multiple follicular units, and then transplanting the follicular units into the area that needs to be transplanted through microsurgical techniques. After having a hair transplant, if the individual has a better constitution, the hair follicles will recover faster and the Minoxidil tincture will be used for a shorter period of time, which will take about six months to a year. If the individual is in poor health and the hair follicles recover more slowly, the minoxidil tincture will take longer to use, about a year to a year and a half. Minoxidil tincture can promote hair growth, but can not be used privately, you need to use the drug under the guidance of a professional doctor. Adverse reactions to Minoxidil tincture include irritant dermatitis, allergies, and dizziness. Minoxidil tincture is contraindicated for those who are allergic to any of the ingredients.
