Tinting not lasting

[Elaine D]

Recently I have had a few clients tell me their tinting is not lasting.

Everything looks perfect when I finish and leave clients.

It is any colour so it cannot be the colour to blame but it is the same peroxide bottle.

Any idea as to what it could be?

Thanks in advance.

How long has your peroxide been open? If it's a while it might be worth changing as it's not so effective after a period of time
