Hair loss and thyroid disease

Hair loss happens for many reasons. It may be genetics, your lifestyle or a particular condition which has a negative effect on your hair. Today, we want to highlight a condition which effects 1 in 20 people here in the UK alone. We’re going to talk you through what thyroid disease is, the different types, the effects it has on you and your hair.

What is thyroid disease?

First of all, we all have a thyroid. It’s located at the front of your windpipe in your neck. The thyroid gland is shaped like a butterfly and it’s job is to produce a hormone called thyroxine and triiodothyronine, a hormone involved with the metabolism. Thyroid disease occurs when the thyroid gland is not working correctly. This could be either producing too much thyroxine or not producing enough.

Hypothyroidism / underactive thyroid

We’ll start with the underactive thyroid. An underactive thyroid does not produce enough thyroxine – a hormone which our bodies need to perform at its optimum. Many of the body’s functions slow down when the thyroid doesn’t produce enough of this hormone. How will you feel if you have an underactive thyroid you say? The three main symptoms are:

  • Tiredness
  • Weight gain
  • Depression

Unfortunately, hypothyroidism cannot be prevented. However, it can be treated! It will be necessary to take hormone medication on a daily basis for the rest of your life, but the medication will replace the hormone deficiency you’ll be experiencing.

We’re sorry to say this ladies, but hypothyroidism is more common in women than men. It is also possible for children to have an underactive thyroid, with some babies being born with the condition.

Hyperthyroidism / overactive thyroid

An overactive thyroid is when our thyroid gland is producing too much hormone. Again, this is not healthy for your organs or general wellbeing.

Hyperthyroidism is ten times more likely to occur in women than men. The symptoms include:

  • Anxiety and nervousness
  • Mood swings
  • Twitching or trembling
  • Weight loss
  • Difficulty sleeping
  • Sensitivity to heat
  • Tiredness or weakness
  • Swelling around the thyroid gland
  • Heart palpitations

Thyroid disease can be diagnosed by a simple blood test – see your GP if you’re concerned and feel you would benefit from checking your thyroid function.

If you suffer from thyroid disease, you may notice a change in your hair’s condition. As your hormone levels are disrupted by thyroid disease, this may lead to disrupted bodily functions, such as the development of your hair at the root.

Although hair loss through thyroid disease can be temporary, it can take several months to regain strength and thickness once the medication starts to become effective.

In the meantime, PHL products can assist the healthy growth of your hair by strengthening, nourishing and encouraging hair regrowth, whilst preventing hair loss.
