Minoxidil is causing irritation on scalp. Is there is any way to prevent side effects of minoxidil?

This requires an in-person evaluation. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

Redness after use of minoxidil  is a common side effect. Serum may cause irritation of the skin, redness, dryness, itchiness and dandruff because of alchol content of minoxidil  and very rarely dizziness or even heart palpitations. It would be better to  consider using a lower dose/percentage. All of side effects are assumed to go away soon after stopping to use it.

Most likely cause of irritation from minoxidil is typically the solvent that it is mixed with. The solvent typically is propylene glycol, and must be avoided. If you use a foam solution solution, then these are usually mix with isopropyl alcohol and usually cause less irritation.In summary, use foam over liquid if liquid is causing irritation. You can also Applied minoxidil with your hair slightly damp.
