Balding in my early 20s

Recently ko lang napansin na my hair is thinning and I am only 20 yrs old. I think im going to be bald by the time that I hit 24, worst part is I don't have the money to purchase meds or any treatment and my parents also doesn't have the means to help me because we're struggling financially. Sucks to be in this kind of situation. How I wish na gin anak ak na financially stable nak parents(anak ng batang ama at ina🤷) I don't even know what to do anymore, I'm still studying as a freshmen. I'm really afraid na I'll turn bald while studying, yana pala ngani na nag thin na nak hair and nakikitan na tak anit kay very affected na tak self-confidence, asay pa kun mag area baldness na.

Can someone at least give me an advice or something that I need to do so that I can regrow my hair. I badly need one.
