Minoxidil 2% – What happens after its intake?
Only the 2% concentration of minoxidil has been approved for use in women. Women appear to be generally more sensitive to the side effects of minoxidil, in terms of lowering blood pressure (hypotension) and lightheadedness from the intake of the medication.
Women also have an increased risk of allergic skin reactions (contact dermatitis). An annoying topical reaction which may sometimes develop in women treated with minoxidil is the development of hair growth in the face.
Although this unwanted hair slowly breaks when the drug is stopped, it is occasionally necessary to remove it from the face.
The careful application of the drug to avoid dripping on the cheekbones and forehead seems to reduce, but does not completely prevent, the appearance of this phenomenon. There is a significantly higher incidence of these side effects when the 5% solution is used.
