There are quite a number of factors which can trigger increased/excessive hair shedding. I will cover the major/most common triggers below:
1. High levels of stress
2. Medications/treatments Some people find that medications like oral contraceptives, medications for treating hyperthyroid and hypothyroid can trigger increased hair shedding.
3. Crash dieting/low protein & iron diets
4. Age and Heredity As you get older, the rate of shedding increases and your hair is not replaced as fast as before. This is why people start to see thinning in their scalp. This rate of thinning is genetic.
5. Pregnancy Hormonal changes The surge in hormones when a woman is pregnant usually locks your hair in the growing phase which explains why some women tend to see their hair growing and thriving like crazy! Unfortunately, once the baby arrives, the hormones take a nose dive back to the pre-pregnancy levels and this leads to shedding. You will have hair which should have shed during the pregnancy stage as well as those from the non pregnancy stage all shedding at once. This is why it may like all your hair is falling out. This tends to happen within the first 3-6months after the baby arrives.
Some people suggest pre-natal vitamins to help combat this. Unfortunately, this does not actually work in most cases. This also applies to extending or prematurely stopping breastfeeding. For pregnancy related changes, shedding will balance out after about 6 months. Sadly, you just have to give it some time.
6. Climatic/seasonal There is some research to show that the seasons can affect our rate of shedding. It shows that shedding may be highest during autumn and lowest during spring.
7. Use of chemicals like dyes, bleach and relaxers directly on your scalp
