Questions
Colour-treated hair, answered
01 How soon can you wash hair after colouring?
Wait 72 hours. The cuticle stays partly open while the colour settles, and washing inside that window costs more pigment than any single week that follows.
02 Do sulfate-free shampoos really preserve colour?
Yes, measurably. Sulfate surfactants such as sodium lauryl sulfate strip pigment along with sebum. Milder systems built on cocamidopropyl betaine remove noticeably less, though the label alone means nothing, check the first five INCI entries.
03 Why does red hair colour fade fastest?
Red pigment molecules are the smallest of the permanent dyes, so they escape the cortex through a lifted cuticle faster than brown or black. Red also oxidises quickest under UV.
