L’Oreal has come under fire from consumers due to the after effects of its Colorista hair dye, with many users taking to social media to slam the dye for turning their hair green.

A semi-permanent dye that is said to wash out in one to two weeks, many fans took to sites such as Instagram to suggest the dye had continued to leave a green tinge some weeks and months later. 

Statements included, “L’Oreal Colorista hair dye in purple turned my hair GREEN. I’ve been using semi perm. hair dyes for years, THIS IS THE WORSE THING EVER.” While user Kayleigh wrote, “Never use L’Oreal Colorista washout, put the blue one in my hair in Feb. came out green never washed out and now bleach won’t take it out.” (sic)

In a statement to the Metro.co.uk, L’Oréal said, “The Colorista brand offers a new approach to delivering a range of colour effects to the hair – from cool pastel shades to super bright hair colours.
“As with all hair colour products, the end-result will vary from individual to individual based different factors, including application techniques, hair condition and hair colour history.
“L’Oréal Paris takes all feedback from our consumers very seriously. We will investigate this matter further and will take the appropriate decisions regarding the particular shades.”
