My Dear Welcome to Healthcaremagic! I have noted your concerns and find that your history and details closely match that of Telogen Effluvium, a diffuse condition of scalp hair loss in which multiple factors might be playing an important part and where the symptoms may come and go just as in your case. The condition can follow stressful factors like it started with the tragic loss of your father. my patients recover from TE with following measures. 1 Use of comb or brush frequently but without vigorous force being applied 2 balanced diet rich in fresh fruits and vegetables 3 Biotin tablets 4 Stimulants for hair roots like Folica solution or cantharidine oil 5 Treating the hairs gently and avoiding use of chemicals on the scalp 6 Stress relief by meditation and engaging in hobbies I am sure that with some of these measures suitable to your temperament, you will be benefited to a good measure. Best wishes!
