Hi. Greetings. Thank you for the detailed history. Hard water may make hair rough and cause temporary frizzing or entanglement or hair breakage. In women, Anaemia, hormonal issues, environmental factors , pollution, stress, junk food and poor diet could cause you to lose hair. After adequate evaluation by dermatologist, You'll probably need treatment with hair care lotions or serums - something that has vasodilator properties and improves thickness of hair and reduces hair loss. Continue to Have a good balanced nutritious diet. Use a sls free shampoo. See a dermatologist near you to get evaluated if you have any other scalp problem. Hope this helps. For any further queries, please write at follow up message chat. Warm regards. Dr Govind Suresh Mittal. Excel care hospital, Bangalore.
