Colour change on peroxide developer
Have any other hairdressers bought the S-Pro peroxide and noticed the colour coding has changed 40 Vol has always been blue and they changed their colours to one standard colour where the gradient got darker as the stength got higher I have been informed due to several complaints, they have took this feedback on board and reverted back to the old style colours in July 2020 I can see from the website the colours are still showing as the gradient getting darker. Sally's have failed to advise me of this colour change so failed in their duty of care to advise these changes when buying this product
