That’s lazy work in my opinion. Precision is important for ensuring consistency so if they’re employed you need to set your expectations with a series of simple policies and ensure they stick to them.

What sort of reaction and how severe is it?
Realistically, it’s more likely the reaction is to the PPD in the tint, which isn’t affected by the peroxide strength.

Had the client been given a skin test 48 hours previously?

The client has done every 4 weeks with no reaction at all

You haven’t said what sort of reaction occurred?

I had assumed that as it was a highlift tint, it was applied in foils because you’d never use 40vol on the scalp.
That’s obviously going to cause pain and discomfort.
