If you’re struggling with hair loss and think it may be due to hypothyroidism, you’re not alone. Many people with this condition experience thinning hair or hair loss. While there is no cure for hypothyroidism, there are treatments that can help manage the condition and improve your symptoms, including hair loss. If you think your hair loss may be due to hypothyroidism, talk to your doctor about treatment options.

Your hair grows from the follicles on the scalp. Therefore, with the massage of the scalp, blood circulation increases and hair growth improves. Hair growth is a cycle and it includes hair growth as well as the resting phase. The thyroid gland is present in the lower part of your neck and it produces thyroid hormones. These hormones control your mood, weight as well as your ability to think.

Thyroid hormones also affect your hair growth cycle. According to experts, it is common to lose 50 – 100 hair strands per day. These hormones affect the formation and development of hair follicles. Thyroid problems caused due to T3 and T4 can cause hair loss. These thyroid problems in turn are caused due to several autoimmune conditions.  

According to a study published in the British journal of dermatology, loss of scalp, eyebrows, and body hair are characteristic signs of thyroid deficiency. Hair loss is a common effect of thyroid problems but the good thing is that it is not permanent. 

Does hypothyroidism cause hair loss?

Hair loss is a common side effect of thyroid hormonal imbalance. Both hypothyroidism and hyperthyroidism cause can cause hair loss problems. As discussed earlier, hair growth is a cycle. But if the cycle stays in the resting phase for a long time it can cause thinning of hair or even baldness.

This kind of hair loss is known as telogen. In this condition, more than normal hair fall occurs, or the growth of hair is reduced. The hair that is in the growth stage enters the shedding stage. The use of the hormone ‘levothyroxine (Levothroid, Levoxyl, Synthroid, or Unithroid)’ to treat hypothyroidism can also cause hair loss. So, one should avoid self-medication regarding thyroid hormone imbalance as an overactive thyroid can also be a cause of hair loss.
