The minoxidil hair loss treatment has the ability to reverse or slow down the hair loss process. This kind of treatment expands small blood vessels and if this is applied twice daily on the affected area of the human scalp, it has been shown to stimulate hair regrowth by enhancing cell proliferation which is the growth and production of cells by multiplication of parts.

Researchers were able to produce 2% and 5% minoxidil topical solutions. The 5% concentration is preferably intended for men, whereas the 2% concentration solutions are intended for women. The 5% concentrated solution is probably more efficient than the 2% concentrated solution although the 5% solution shows a greater result of irritation than the 2%. The most common side effect is itchy scalp.
