The GHD site points out that clean straighteners are essential for a ‘good hair day’.

The site’s advice explains: “Ceramic plates of straighteners can harbour grime if not properly cleaned.

“Hairspray, oils and other heavy products can build up not only on your hair but on your tools too.

“They’ll sit on top of oils that are secreted from your scalp, which can damage your locks if the device is not regularly cleaned.”
