We're often told to avoid heat at all costs when it comes to styling our hair. It's been said it strips your locks of natural oils and can lead to breakages and frizzy hair.
However an expert says it can in fact be more damaging to let your hair dry naturally - and in fact makes it greasier. Content creator Abbey Yung, who is currently in training to get her trichology certificate, shared the "mind-blowing" information she learned while studying.
According to Abbey, your hair will naturally lose excess oil in other ways, but blow drying your hair essentially kickstarts it. In a recent video on her @abbeyyung TikTok page, she said: "You will never air dry ever again after I tell you this."
