Perhaps you'll be surprised to know that usually we lose up to 50-100 hairs per day. That's why you shouldn't be anxious if you find some hair on the bottom of your tub. Moreover, hair loss might vary from season to season. So if you lose 50 hairs per summer day – it's okay. If hair loss is about 150 hairs per day in winter – that's also known as normal.
The amount of the lost hair depends on the general condition of your body. If your organism suffers from vitamin deficiency, it's quite natural that your body will negatively react to the lack of minerals and other essential nutrients.
