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.
