Underactive Thyroid & Hair Loss

There are many medical conditions that can cause hair loss, with thyroid disease being a common culprit. Underactive thyroid can cause your thyroid hormone levels to go too low or too high and one of the effects of this imbalance is hair loss. Hair that was once lusciously thick and full of life can become excessively dry, brittle or thin. Although this is a common side effect it’s not a permanent problem as long as you get the correct medication.

So how does an underactive thyroid cause hair loss?

Your hair follicles follow a natural cycle of hair growth and resting stages. As most of your hair is growing some of it is resting. But when changes occur in the body that mess up your cycle too much hair rests at one time and not enough grows which is what leads to hair falling out.

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. Once you start your treatment and your thyroid hormone levels stabilise the hair loss should resolve itself. Healthy hormone levels = healthy hair growth. Remember it may take some time to find the right dosage of levothyroxine to get your thyroid under control.

What can I do to look after my hair more?

  • Use Hair Oils

Massage your hair with oil like: Coconut oil, argan oil or almond oil and leave in overnight or for a few hours before washing. This should help with the dryness and help keep your hair looking healthy.

  • Change Your Shampoo

Use sodium laurel sulphate or sodium laureate sulphate (SLS) free shampoos. They are much more gentler on your hair compared to the other shampoos.

  • Say No to Heat

Don’t overuse heated styling tools such as, straighteners, hair dryers and curlers. They’ll only damage your hair more so try keep it to once a week.

  • Wash Your Hair Less

Don’t wash your hair too much because you’re washing away all your natural oils. Most underactive thyroid sufferers will have dry hair anyway so you can get away with washing it 2/3 times a week.

Losing your hair can be really tough and can badly affect your confidence. There’s so many smart ways you can style your hair so it looks thicker or you can wear hair extensions if you want to. But always remember you’re more than just the hair on your head so keep smiling and keep going.
