@thebullyeagleIt is likely you’re hair is shifting in to its “mature hairline” phase, which does seem early at 15, but certainly not impossible. It can usually occur at around age 17, but others can experience it earlier. As you mentioned that you will see a dermatologist then they can certainly take a look and investigate what’s happening. Absolutely nobody should even be considering Fin at you’re age, no Dr/Gp would even consider prescribing it. You already mentioned this in you’re first post. There is a difference between receding and a mature hairline, it is possible to lose hair from a early age, but I don’t think this is MPB. Definitely other options can be considered when you reach 18, if needed. With a high likelihood of future balding possible (family history) then it’s better to be proactive, i understand the concern here. Best advice ? Seek medical help as you intend too, dermatologist/trichologist etc.
