WOMEN who dye their hair know that there is a real tendency for the tint to change into a rather orangey shade at times.
This has usually been seen as more of a problem for blondes, but brunettes too can notice their hair taking on a rather coppery sheen as they fade.
The use of purple shampoo has been seen as the solution for blondes for a while now. The idea is that it cancels out the yellowy hue that can sometimes spoil the look of dyed blonde hair.
Using the same principle of colour-correcting unwanted shades the idea is to darken hues in dyed brunette fair by using a blue shampoo.
The idea is that blue cancels orange – so you can neutralize a brassy looking shade by using blue shampoo.
Experts suggest using the coloured shampoo every two days if you have noticed your hair taking on an orangey tint, then once a week after that.
Blondes should stick to purple shampoo, and brunettes to blue – the two are not interchangeable.
