I’m only 17 years old and already shedding quite a bit of hair. I have a bit of receding hairline but have a lots of hair. I don’t seem to lose that much long hair I’m acutally more concerned about the short hair I’m losing. I’ve never had dandruff till recently and I’ve noticed every time I adjust my hair or run my fingers through it, I see a ton of small hairs fall out, all though the head and shoulders shampoo has helped with my dandruff. I recently gave up smoking weed about 3 weeks ago and work 4 days a week , 8 hour days while attending high school. I don’t feel stressed but I don’t know what I’m dealing with here, any answers?
