How does Topical Thyroid Hormone work?

Our T3 topical thyroid hair regrowth treatment has been found to stimulate hair growth via prolonging of the hair growth phase (anagen) in vitro and in observational studies. This thyroid hair loss formulation is based on HairDAO’s first preclinical study with Dr. Ralf Paus, the most highly cited hair loss researcher in the world. Thyroid hair loss conditions are common in patients with under active thyroid and can be used for both female pattern hair loss in women and male pattern hair loss. For more information about the relationship between thyroid and hair loss, check out the video on this page or our blog linked below. If you are looking for a minoxidil and finasteride alternative with low side effects, try our T3.

Hair Loss and Thyroid: The Complete Guide to Hypothyroidism and Hair Loss

Hair loss affects 30% of people with thyroid issues, yet it's often undiagnosed. Thyroid hormones (especially T3) directly control hair follicle growth cycles. Unlike pattern baldness, thyroid hair loss causes diffuse thinning across the entire scalp. With proper diagnosis and treatment including thyroid hormone optimization, 70-80% of patients see significant regrowth within 6-12 months. Early intervention is key.
