Which is responsible for hair loss T3, T4 or TSH. Lower level or higher level? Is hair loss recovered if thyroid levels are normalised?

Question

Hi lybrate-user, Many medical conditions can cause hair loss, with thyroid disease a common culprit. Thyroid problems include both an underactive thyroid gland (hypothyroidism) and an overactive thyroid gland (hyperthyroidism). Because hair growth depends on the proper functioning of the thyroid gland, abnormal levels of thyroid hormone produced by this gland can result in hair changes, along with many other side effects, if left untreated. When there is too much thyroid hormone, the hair on your head can become fine, with thinning hair all over the scalp. When there is too little of this hormone, there can be hair loss, not just on the scalp, but also anywhere on the body. For further details can online consult.
