Blue Hair Ideas

26th Apr 2023


Unless you are blessed with pristine light blonde hair, you will have to pre-lighten your hair to achieve the perfect blue shade.

Pair your blue with the most amazing contrasting money piece for extra impact!

Lift 2 or 3 shades at a time, then let your hair rest.

If your hair is very yellow, your blue may go in a teal direction, super cute!

Blue Green Hair 

Blue hair with green tones is at the highest risk of turning green.

Blue shampoo will help you maintain the blue pigments in-between colour sessions.

Blue Shampoo

Once you have reached your perfect blue, prevent that inevitable fade for as long as possible using our Blue Colour Shampoo.

Blue Shampoo acts as a blue toner, depositing pigment into the hair. This prevents green tones from appearing, which can happen as blue hair dye fades.

Lilac/Blue Hair

Want to take your blue to the purple side?

Make sure your blue hair has no dominant green tones, this works best when the base is a level 10/11 hair, with no warm undertones.

Midnight Blue Hair

Like your blues cool, dark and mysterious? Then Sapphire is what you need!

A deep dark blue, like Sapphire can even tint dark hair to give a subtle navy sheen, likely to be most noticeable by daylight.
