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.
Reasons for hair loss
- The factors below can cause excessive hair shedding or telogen effluvium.
- On a diet
- Post-pregnancy hormonal changes
- Taking birth control pills

Your hair cycle will recover in 3 to 9 months in case that your hair loss is only one-off. For the case of enduring lots of stress, you will notice that the hair loss may not stop unless your circumstances change too.
Sometimes when you are suffering from stress or illness physically, the first physical signs can be found is your hair.
Hair Growth Cycle
As for hair growth cycle, basically, each one contains three main stages—Anagen, Catagen and Telogen.
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 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 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.
