YES, only if the hair has been dyed or bleached. Our Bio Straight Treatment can cause the hair to lift up to 5 tones and can cause blonde hair to go brassy. We recommend to book your clients in for a colour refresh 5-7 days after the treatment. To minimise the colour change, rinse the hair more and use the straightener at a lower temperature. We recommend between 180-190C.
Colouring the hair should always be AFTER the treatment, no earlier than 5-7 days after. This is because the organic acids can strip the hair colour up to 5 tones.
