Hi. Greetings. 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. Have a good balanced nutritious diet. See a dermatologist near you to get evaluated if you have any other scalp problem. Hope this helps. Further queries or appointment requests may be sent on follow up messaging. Warm regards. Dr Govind Suresh Mittal.
