Why shouldn't I use a 40 volume developer with foils?

Asked by La_chica_gomela (12547points) August 31st, 2010

I went to Sally’s and told the girl what I was looking for, something that will lift pretty much all the pigment out, I want the hair I’m going to use it on to be white. She gave me L’oreal Quick Blue and Salon Care 40 Volume Developer. Now that I’m home, the Quick Blue package says to use a 20 or 30 volume developer with foils or plastic and a 20, 30, or 40 volume for “open air techniques”.

The problem is I definitely need to use foils or plastic, or I’ll make a huge mess. This has been proven many times.

I can’t find anything online or on the package as to WHY I shouldn’t use 40 volume with foils or plastic. The only thing I can think of is it might be too harsh on the hair.

Insight please?

It might be too strong for the foils, too! Aluminium is thin!

It shouldn’t be too strong for the foils. I’ve used 40 vol when foiling many times before and had no problems.

I imagine that the problem is the potential damage to the hair. 40 is the strongest developer, so the potential to fry your hair is pretty real. I’ve never seen or heard such a warning… I wonder if it is something specific to the brand you’re using.

Is there a phone number on the bottle or packaging? Perhaps you can call the company.

When you“re foiling hair, it’s time consuming. Therefore, the bleach stays on your hair considerably longer than doing an “open air” bleach. 40 volume provides more lift (of color) than 20 or 30, and the longer bleach is on your hair, the more damage it can cause in the form of weakness, possibly resulting in breakage. Lesser volume helps to ensure that, while the bleach is on your hair for a lengthy amount of time, it will lighten it causing little damage. I hope this clarifies things for you.
