21 year old, losing hair and have no idea what to do.

[WinTerr]

Hello, guys. I never thought I'd have to go here but I guess I should try. I would like to know how bad it is. I always had very thin hair since forever and when the light hit them it would easily shine through. Just recently, for about 3-4 months I noticed my head itching and been getting this weird tingling feeling on the head, guess it's the hair falling out? Seems so. Also, I always have bad dandruff, I always use anti-dandruff shampoo but it never fully helps, if I stop using it can be pretty bad.

What do you guys think? Should I just go and start taking fin and minox now or something else?

P.S. sorry about the bad pictures.
