TLDR Hypothyroidism can cause hair loss, which is often reversible with treatment.
Alopecia is frequently observed in hypothyroidism, affecting up to 50% of patients, and is linked to decreased thyroid hormone's impact on peripheral vasoconstriction, sebum secretion, hair growth rate, and increased telogen hairs. Restoring normal thyroid levels can reverse hair loss unless follicles are atrophied. Autoimmune thyroid disorders may need additional treatments like minoxidil, laser therapy, microneedling, corticosteroids, PRP injections, and dietary supplements. Oral minoxidil is effective for those struggling with topical forms. PRP shows promise in improving hair loss and quality of life, but more large-scale studies are needed to confirm its efficacy and standardize protocols.
