Ppd in purple shampoos?

[babychops]

I have a client who is allergic to ppd in hair colours. Is she safe using purple shampoos? Osmo super silver specifically. I can’t seem to find any information on it?

Purple shampoos don’t contain permanent colour so chances are, she’d be fine with it . However, I think the fact that the Osmo super silver in particular, is very purple and that she’s stated she’s allergic to ppd (and therefore, possibly other chemicals), I think you’d still need to do a patch test first, to satisfy your insurance requirements.
