One surprising reason behind hair thinning

Hair has always been a symbol of a woman's identity throughout history. A day at the hairdresser can boost our self-confidence and a bad hair day can put us in a funk.


Thinning or brittle hair, hair loss and overall bad looking hair are often attributed to environmental factors, nutrition, age and stress levels. If your hair has always been that way, it’s most likely genetic. It can also stem from bad habits like excessive hair dying and heat exposure. But there's one other reason that might surprise you.

It might be your thyroid.

Your hair is getting thinner and thinner

If you notice that more of your hair is falling out than usual, you might be dealing with a “lazy” thyroid. 

Thyroid hormones can directly alter human hair follicles and their life cycle.* If the hair follicle is altered in a negative way, the hair will appear thinner.

Your hair is brittle

Brittle hair is a mixture of frizzy, split-end, dull, dry, and lifeless hair. It manifests itself in a variety of ways, from minor dullness to full-blown hair loss and breakage, just like dry skin.

If you're wondering why your hair is brittle, the biggest culprits are excessive washing, usage of heat and poor nutrition, and sometimes a sluggish thyroid. For healthy hair, eat foods that are rich in vitamins and minerals and try not to wash it every day.

The takeaway

As you can see, apart from the environmental and age factors, hormones can have a huge influence on how your hair looks. 

However, there is some good news!

Bad habits and hormone-related hair thinning is usually temporary and reversible! Once your levels are stabilised and you improve your habits as an extra, your hair should slowly return back to normal. The bad news? It can take months, so it’s recommendable that you do the treatment over the course of 3-6 months.

Another thing you can do to support normal thyroid function is to take a high-quality supplement specially designed for your thyroid.
