Can I go bald in an year or two I've been receding 2 years don't wanna wait two more

[THECOMEBACKKID12345]

In my case I'm 15 receding and thinning since 13 it's really bad and my dad just says to accept but he doesn't know since he has fullness of hair. I want to wait till like 17 to start using minoxidil since I'll be older but I'm scared tht it will be too late then considering the speed my hair is falling. I'd really appreciate professional opinion as well as personal experiences. And if I want to attach a pic pls tell me how to do so thanks!
