It's something we've never really thought about.

Most of us have had our hair straighteners and curlers for years now. Whether it's the GHD you got for Christmas during your first year at college or the curler you bought yourself a year back, we use them weekly - if not daily - and don't think anything about it. However, it turns out that we should be cleaning them. But HOW? Moe Harb, a stylist at Moe Harb London in Harrods told Metro, that hair straighteners and curlers collect a bunch of grease and hair oils and sprays and just dirt in general. Makes sense when you think about it. Moe told the publication that it's best to clean them when they're still warm. After using one, let it cool down a tiny bit (obvs, it shouldn't be scalding) and then follow his tips: "There are two types of curlers: one ceramic and one metal. You can use kitchen cleaning products for ceramic and for the metal, use a wet towel and wipe over everywhere, being careful not to burn yourself." He added: "Do not use a scour as this can remove the coating on the plate or heated barrel." If you use your tools daily, they'll need to be cleaned every three months, but if you only use them every once in a while, every nine months is fine.
