Dandruff is not caused by poor hygiene, contrary to popular belief.
Dandruff is caused by lots of conditions such as seborrheic dermatitis, ringworm, and eczema.
It may be made worse by stress and cold weather.
It is worth noting that both hair loss and dandruff can be made worse by stress.
This means if you are losing hair due to stress and also have dandruff, you may think the dandruff is causing your hair loss instead of the stress.
