what to do when i take shower and hair fall

Hello and thank you for choosing EmpowHer,
Hair loss can have many causes. Some of the simplest and most common causes is poor nutrition and overall health. In these cases hair loss can be improved by eating a non-processed, natural diet and taking supplements. The are also many over-the-counter "skin, hair, nail" supplements available.
There are other causes such as pregnancy or postpartum, menopause, vitamin-deficiencies, or thyroid problems.
The treatment will depend greatly on the cause. So you will need to do some personal assessments to determine what you think the cause may be.
