Simply being out in the sun does not directly cause alopecia, however, prolonged exposure to UV radiation can damage the condition of the hair and scalp. The sun’s rays primarily affect the hair shaft, which over time can become drier, duller and more prone to damage.

It is worth remembering that hair outside the scalp is a dead structure and therefore does not regenerate on its own. Excessive exposure to the sun can damage its surface and increase the risk of breakage. As a result, your hair may appear thinner, even though the number of active hair follicles remains unchanged.

UV radiation can also affect the scalp. Prolonged exposure without protection can lead to dryness, irritation or increased oxidative stress.

That is why, in summer, it is a good idea to use sun protection for your hair and scalp as well. Wearing a hat, using suitable skincare products and avoiding spending long hours in direct sunlight can help minimise the harmful effects of UV radiation.
