Also if you're young, you like having long hair, you have fine hair and MPB runs in your family, be careful with cutting hair too short. I had absolutely luscious locks but age 19, after a bad haircut, receding hairline and thinning peak went absolutely hogwild and destroyed my hair. Also try to refrain from overwashing but you should pretty much always feel "clean enough". Been using rogaine and finasteride for years trying to reclaim what was lost.
