Yes, tanning can affect hair. The UV rays from the sun or sunbed can damage the protein in your hair, making it dry and brittle. This can lead to split ends and breakage. It’s especially important to protect your hair if it’s colour-treated, as the UV rays can cause the colour to fade. Wearing a hat or scarf is a good way to protect your hair from the sun’s rays. You can also use a leave-in conditioner or serum to help keep your hair healthy while you’re spending time in the sun.
