I've had some mild dandruff and hairfall associated with them since past two months. To treat dandruff, i started ketaconozole shampoo and ketaconozole lotion at night in the start of Jan. I also changed water, and started washing hairs from drinking water because of water hardness problem in my area, but suddenly from the starting of February, my hairs are shedding too much, almost thrice of what they were falling before and my scalp itches very badly. When i wash my hair, water is a little soothing but as soon as it starts to dry, itching comes back. Oiling seems to be a problem because it makes itching worse. It seems scalp is inflamed. What should I do in that case? Should I wash everyday? Should I keep using ketaconozole shampoo?
