Alopecia simply means hair loss. On the average, the scalp contains approximately 100,000 to 150,000 hair. The normal hair life cycle is 2-3 years. Ninety percent of the hair on the scalp grows continuously and about 10% of the hair is in a resting phase. Every 2-3 months, the resting hair is shed and new hair starts to grow to replace it. That is why it is normal to shed some hair every day. Normally, you lose around a hundred hair strands every day but others may experience abnormal hair loss.
Hair loss can be caused by a variety of reasons like genetics, age, medication, diseases and other conditions.
