<human>: I've decided that this year I am going to try and solve one of the biggest problems I have. My hair. Or, lack thereof.

Since last year, I've noticed that my hair has been looking thinner and thinner, and It's not been a huge problem until recently, when I got it cut pretty short. I've discovered that my hair is thinning very quickly, and that it is falling out faster as well. I've started to eat healthier, work out more, and I'm taking multivitamins to help, but It doesn't appear to be doing much. And here's the kicker:

You may think this is some thirty-something redditor looking for a solution to aging, but I am only 19 years old, and this started around 18. I'm pretty sure hair loss isn't common at this age. I want to try and reverse this.

Any advice or knowledge on this subject would be greatly appreciated. Thank you in advance!
