If I Use Minoxidil Without MPB, Is It Going to Ruin My Healthy Hair?

If I do not actually have mpb and was just thinning naturally to a certain point (I was always more of a diffuse thinner) is taking minoxidil doing more harm than good? I know it says on the medication do not use unless you have mpb, but then as I am aware, hairs that are healthy are not affected by the minox, so why does it matter if you use it?

surely any hair that regrows will be lost upon ceasing the medication, yet would I not just end up with my original thin hair situation when it no longer works (or perhaps a little below baseline)?

It shouldn’t ruin healthy hair, but it could cause an initial shedding that some people have reported.

But really… if you don’t know what you have or you don’t have a clear diagnosis, I don’t think it is a smart practice to treat yourself with medication. Get a doctor’s diagnosis first before you try to treat a specific condition that you may not even have!
