Hello..
Well there are no symptoms which suggest that it is because of hormonal imbalances..We need to do blood test for that...But then there are more common causes like anemia, dandruff, pollutionel, genetic or due to changes in weather,water food intake as in protein insufficiency,
calcium deficiency, anaemia etc... I need to examine you for that...its better you consult a dermatologist... Make sure to have protein rich diet..have good green leafy vegetables, dry fruits etc..drink plenty of water too
