Hello Vinu, you seem to be suffering from telogen effluvium, the major differential of this condition is female pattern hair loss. You need to visit a dermatologist for trichoscopy to differntiate the two conditions, for Telogen effluvium, u need inv. like serum ferritin and thyroid function tests, and if normal, there are hair supplements that will help you in the control..for female pattern hair loss, the therapy comprises of 2% minoxidil lotion. This isnot a shampoo or water problem, although shampoos with harsh chemicals damages the roots, so, use a shampoo like Xgain and condition ur hair with a good conditioner after that. I hope you will find this piece of info useful Thanks TK
