Hair Loss in men has been rampant in recent years. Losing hair is a natural activity and about 85% of hair is active and in the growing phase (anagen) and the rest 15% is in the resting phase (telogen). Thus you tend to lose about 100 hairs every day and that is quite normal. And this also shows that hair loss is actually quite paradoxical, you lose hair to grow more. But there are times when you will lose more hair and you will also seem to notice that you lose hair in patches and also your hair starts to grow thin. But even this can be explained when it happens within a short time, it may be because you had a fever or else there was an infection which caused the temporary shock and your body will recover within 3 or 4 weeks after the cause subsides.
