Is this normal hair loss for a 17 y/o?? Granted I just dyed my hair, but it's usually about this much anyways. (In shower is where I always notice my hair loss) Its very worrying because I've been taking my hair skin and nails vitamins for about 4-5 months now and it hasnt helped my hair to be stronger. Also I take pretty food care of my hair, I use good shampoos and conditioners, seriums, anti frizz, and barley use heat on my hair ( like a total of maybe 5-6 times since last year)

I have very thick hair but I've noticed I have a cow-lick looking spot that's very very sensitive.
