Here's Why Air-Drying Your Hair Could Be Damaging Your Strands

We’re shook.

Lockdown fatigue is well and truly kicking in, huh?

No amount of banana bread and beginners’ yoga will save us now.

But we find it helps to think about the small positives quarantine is bringing us, such as no work commute, being able to wear pimple patches around the house, having the time to wash our make-up brushes and watch a whole Netflix series in one go.

Another thing we’ve been feeling really smug about is wafting around the house after our shower and letting our hair dry naturally—a “heat holiday,” if you like. Surely we’ll all have the hair of a Kardashian by the time we return to normal life, yes?

No. No, we will not.

Because scientists at GHD have revealed that our hair fibers swell and become weaker when wet, and the longer that swelling goes on for, the more pressure it puts on the delicate proteins that keep our hair intact.



Celebrity hairstylist Adam Reed (he’s GHD’s global ambassador and has coiffed the likes of Ellie Goulding, Diane Kruger, and Sophie Dahl) concurs, explaining that hair can absorb up to 30 percent of its own weight in water. “Do not let your hair air dry," he confirms. "It is a total myth that this is good for your hair!”


“Start by using a scrunching motion when towel drying,” Moore tells us. “Rubbing the towel across wet hair will cause it to break more easily.” He then advises you to spritz your hair with a heat protectant spray to prevent vertical cracks inside the cuticle, which can lead to split ends and irreversible damage.

Next up, start blow-drying your hair on the lowest setting, slowly increasing the heat as the hair becomes drier. “As the hair dries, the temperature can be increased since the denaturation temperature increases," explains Moore. "When you start to feel your hair warm up, that’s your signal to start turning up the heat on your hairdryer, finally setting your style using the highest temperature.”
