Minoxidil is used against head hair loss. Even though there is a talk that it works wonders on eyebrows, too, it is not approved for use on the eyebrows area. The skin over the eyes is much more sensitive than on the head, and minoxidil can cause skin irritation, itching, and scaling. Besides, there is a high chance of getting it in the eyes while applying. In addition, minoxidil must be used regularly without stopping as discontinuing can cause permanent hair loss.
