If you have thinning hair but you don't lose hair when you tugging on it does that mean the the thinning is caused but lack of vitamins and too much time in front of the computer? Does thinning hair always mean your going bald??
I am a 19 year old male and what I meant by sitting by the computer is that I stay all day at home quite often

Thinning hair can be caused by a number of things. Your thyroid could be underactive, if you had surgery and had anthestetic, that can cause hair to thin. Hormones, medication, and just plain age and heredity can all play a part in thinning hair. I have never heard of too much time in front of the computer causing thinning hair, so I am sure that isn't the problem. If your hair was coming out in handfuls, I would suggest to have blood work done. But you are to lose 100 hairs a day, but the ones you lose have already replenished themselves. Hope this helps!
