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.

You have a few options here. Depending on what type of Minoxidil you're taking, there are differeing ways to apply it that will be less likely to cause the irritation. There are also some good options altogether that may be able to help your hair instead- talk to a doctor to discuss which is the best option for you.

Thank you for the post and question. what percentage Minoxidil are you using? If you are on 5% Minoxidil, try lowering it to 2% or 3% and see if that can help. If you still can not tolerate the side effects, you may want to consider PRP. Hope this helps. Best. 

The irritation may be normal or may be an allergy. Be sure to discuss with your physician before changing plans. If it is irritation, options are to us the foam (which lacks propylene glycol) or to compound minoxidil in a weak corticosteroid (such as triamcinolone acetonide).

Dear mostly minoxidil liquid comes in alcohol based combination which causes irritation...try Minoxidil Foam which is water based and in most of the cases very tolerable...
in case of irritation stop using it and use betamethasone lotion twice a day for few days...

If the form of minoxidil is irritating, you might switch it from liquid to foam or visa versa if that is what you are using. If that doesn't help, then you could be allergic to the minoxidil
