I've heard mixed reviews about finasteride and minoxidil topical products. Some folks swear by them, and others say they didn't notice much of a difference. If you're going down this route, you might want to consult a dermatologist just to make sure it's the right fit for you, especially if you have any medical conditions.
While you're researching products for hair loss, it's a good idea to also consider the health of your existing hair. Sometimes thinning can be exacerbated by poor hair health. For example, did you know you can actually overload your hair with too much protein, making it brittle and more prone to breakage? Learning
how to fix too much protein in hair could be a parallel route to explore. Anyway, I hope this helps and gives you a couple more angles to consider.
