No ... But you may want to see a doctor
I'm 15 and before I had very thick hair. But these past months my hair has been VERY thin. To the point where I have to be careful when combing my hair to save hair strands. Also by my temples there is balding. Do I need to see a doctar?
I would think that would be a good place to start.
"Most people lose about 50 to 100 head hairs a day. These hairs are replaced — they grow back in the same follicle on your head. This amount of hair loss is totally normal and no cause for worry. If you're losing more than that, though, something might be wrong.
If you have hair loss and don't know what's causing it, talk to your doctor. A doctor can determine why the hair is falling out and suggest a treatment that will correct the underlying problem, if necessary." (Internet)
Hair loss can be caused from any number of things .. Typical hair loss is hardly noticable, health issue hair loss (which can even be caused by stress) is often very noticable and so is genetic hair loss.
It wouldn't hurt to see a doctor if you are concerned. At least you will know what is going on.
