Thank you so much for your query. I am sorry because I am very busy now, I can only give a brief answer in English.

Hair Loss is a very stressful situation. And sometimes stress can result in more hair loss (as in the case of Telogen effluvium).

It is good to explain to patients carefully and sympathetically the different causes.
The following website gives a good illustration of different causes of hair loss.

Inherited causes of hair loss implies non reversible and non curable conditions. It is a term that I seldom use unless if the cause is very obvious.

For the above patients, it is good to rule out some reversible causes of hair loss, eg stress (most common), anaemia, thyroid function etc.

Treatments can be given according to diagnoses.

Thank you so much. I wish the patient can get well soon.
