The thing about minoxidil is that shedding and getting worse is something quite common. The shed is normally a good sign that thicker, and stronger hairs will come in. But a thing people also seem to neglect is they think they only have to go through a shed once, but it doesn't work like that every couple of months you are gonna experience a shed that is quite honestly gonna make it look worse before it gets better. It's why people who are young who post should they hop on Minoxidil are warned; simply because once you start minoxidil you have to keep applying it, you can't just get some good results then be like ah I'm done now.
Hair loss is something you have to combat and maintain on a daily basis. Always take before and after pictures, Minoxidil usually takes a minimum of 6 months before you see results possibly longer for people, there's also cases where minoxidil won't benefit the user and they should discontinue. But without pictures provided of before and after its really hard to tell you what to do. Its just that a lot of people mistake "getting better" as actually getting worse because in their mind their hairline wasn't that bad, or they don't remember it being thin in that area. But that's why pictures are useful, I can say that I'm guilty of believing what I had before was better then what I have now, but pictures helped correct that sort of thinking.
