Hands up if you thought leaving your hair to dry naturally was good for it? Yes, same here. After all, we've always been told that heat equals bad news for your locks.

But, it turns out we might have been making a big haircare mistake by letting our hair air-dry – at least according to one expert, ghd's Dr Tim Moore.

Speaking at the launch of the cult brand's new platinum+ straighteners, the beauty expert revealed that leaving your hair wet can place pressure on the strands, ultimately weakening them.

Explaining that you "shouldn't leave your hair wet for any extended period of time", Dr Moore told Yahoo:

"The hair is made up of a cortex, which is the area that pulls the shape of your hair, and then cuticles around the side, which are a bit like roof tiles," he said, before adding that strands swell when they're wet, putting pressure on these cuticles.

"The other thing is that when the hair is wet it loses its strength," he continued. "So, the hair is half as strong when it’s wet."

As a result, Dr Moore told Yahoo that you put your hair at risk of broken and split ends if you leave it soaking wet. Especially because freshly washed hair has just been stripped of its natural oils, which apparently makes it even more vulnerable to damage.

So what should you do instead? Well, to keep your hair in tip top condition, he recommends drying it with a hairdryer on a low heat to remove excess moisture, before turning the temperature up to style your locks as they dry.
