What’s your first reaction when you hear the term “hair shedding”? You may think, “well, terrible”, right? Actually, losing hair is something that happens to us everyday. Of course, the amount of normal hair shedding is within a certain range. Normal hair loss will turn to be abnormal once the total amount is exceeded. So, how much hair loss is normal for women?

Generally speaking, it is normal to lose 50 to 100 hair every day, while the excess of this amount is called abnormal hair loss. Some women will lose up to 150 hair per day. Predominately, hair loss is determined by genetics but certain circumstances play a role in its change.

Hair Growth Cycle

As for hair growth cycle, basically, each one contains three main stages—Anagen, Catagen and Telogen.

Anagen phase

Anagen phase, also called growth phase, lasts for 3 to 5 years, during which hair strand grows around 1.5 cm every month, meaning that your hair can reach the length of 27-45 cm generally. There are some exceptional women who have a growth phase that can last up to 7 years or longer, so their hair can grow to 1 meter in length.

Catagen phase

Catagen phase is a transition phase in hair growth cycle. It is a phase that starts from the end of the anagen phase and lasts for about 10 days. In this phase, hair follicle shrinks and separates from your skin.

Telogen phase

Telogen phase is a resting phase and it lasts for about 3 months. You can find about 10-15% of your hair in this phase at any time. Of course nothing can be found when you are bald. Old hair in this phase sits and waits until a new hair grows through.
