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 may be sent on follow up messaging. Warm regards. Dr Govind Suresh Mittal, Bangalore.
The hair cycle normally consists of growing, resting and falling hairs and there is a delicate balance between these stages of hair cycle. Normally hair should re-grow but if it is not happening, you should consider seeing a dermatologist.

Start on biotin supplements and food rich in iron content. Use a milder shampoo and consider frequent shampooing and conditioning.
One needs to be patient with the treatment protocol as it takes months to see initial improvement.
