When it comes to picking a new tone, you’ll want to opt for a colour that complements your skin’s undertone but also takes into the tone of colour your newly bleached hair sits in.

“You can tell if you have a warm or cool skin tone by the jewellery that you wear. If you tend to suit gold then you have a warm skin tone, and if you tend to suit silver then you have a cool tone,” says Douglas. “If in doubt, opt for a neutral tone in your preferred depth as it will suit both warm and cool skin tones. Essentially, this means that the tone of the colour has an equal amount of primary colours, which results in a balance between cool and warmer tones.”

For a temporary tone fix, the Clairol Colour Gloss Up Conditioners, £8.99, work well, or if you’re looking for a more long-term fix, the Bleach London SuperNatural Colour Kits, £15, are a colour saviour.
