I have thyroid problem and my hair has become very thin and they are falling day by day .shud i drink amla juice. or suggest me some other home remedy?

Level your thyroi: If your thyroid is working properly with the treatment your hair should start improving soon, make sure that your thyroid level is adequate and give your hair sometime.

See a doctor: If you have a true thyroid problem, especially one severe enough to cause hair loss, then you need to see your primary doctor and/or endocrinologist. Thyroid supplementation (prescription) will make you feel much better and improve your symptoms. Low thyroid (if very severe) can eventually become life threatening, so don't just try home remedies!
