You might have visited your doctor to check on the reason for your sudden hair loss and he/she would have told you to check for thyroid levels. You might have wondered what does the thyroid levels have to do with the hair loss. But the irony is that both were interconnected and low or high levels of thyroid hormones might leave you with the nightmare of going bald.
So how are they connected?
Hair follicles follow a natural cycle of hair growth and resting phases. In a given time, most of your hair will be growing while only a small portion of it will be in the resting phase. But when changes in the body disturb that cycle, too much hair rests at one time, resulting in excessive hair loss, hair thinning or balding.
Mild hypothyroidism or hyperthyroidism, or short-lived thyroid problems doesn’t cause hair loss. Severe and prolonged cases of hypothyroidism and hyperthyroidism cause hair loss. The loss is diffuse, involving the entire scalp rather than discrete areas. There are chances of regrowth if the thyroid disorder is treated properly.
Treating Thyroid Disease and Hair Loss
The good news is that once the thyroid disease is diagnosed and the right treatment is prescribed, the hair loss problem resolves on its own. Healthy hormone levels lead to healthy hair growth.
Finasteride is the first oral drug approved by the FDA. We’re talking about a competitive inhibitor of 5-alpha reductase type 2, an enzyme promoting the conversion of testosterone into dihydrotestosterone (DHT) and responsible for hair loss. The biggest effect of Finasteride treatment is observed on the top of the head, and the smallest– in the frontal region. Finasteride is a teratogenic drug; therefore, pregnant women should avoid contact with this medication.
It may take some time but the right treatment will give you the best results. It is suggested to go for hair care products that are free from alcohol and minoxidil. If you’re uncomfortable with the look of your hair while treatment is in progress, you may consider wearing a wig or getting a new hairstyle till the results of your thyroid treatment begin.
Thyroid disease affects other body functions along with hair growth, so make sure to talk to your doctor and get the right treatment.
