Natural colourant
I came across this completely by accident and recalled that there had been a mention here somewhere of PPD-free colour. For what it’s worth.

that’d be because it’s a direct colorant
all direct colorants are PPD-free by nature; you’d only ever use PPD in an oxidative colorant (it’s colourless until it undergoes oxidative polymerisation)“PPD-free” claims on direct colorants are technically correct, but given their context, they’re nearly as nonsensical as “gluten-free” claims on bags of salt -
I agree Bill, infact to substitute PPD in permanent hair colour does not mean absence o diamines. I’ve been trying with 2.5 PTD with pretty good results but the way to a complete range of effective
hair colour is still long.Algar -
I do agree with Bill but in addition to this It may contain Sodium picramate or a natural dyes like Indigo & Henna combination. pH of this kind of hair colors is towards acidic side while in oxidative dyes pH is alkaline when mixed with H2O2.
