Thanks for the query.
You need to consult an endocrinologist and start treatment for your
thyroid ailment as soon as possible, because that may lead to not just hairfall but a number of other symptoms. Hairfall may be controlled with normalization of your thyroid status. You may also benefit with use of minoxidil and certain other supplements. Your dermatologist will decide a treatment plan for you after consultation.
Next Steps
Start on biotin supplements and food rich in iron content. Use a milder shampoo and consider frequent shampooing and conditioning.
