The question isn't if it is safe. Of course, it has to be safe, if it is for sale. I think what you may have meant (but didn't say so) was will it hurt your hair. Or rather, would it destroy your hair.
Of course not. It's not that powerful-- on its own. But you always need to consider what kind of hair you have. Just because it is safe ';for normal hair';, you may be an exception. You really need to understand what is happening when you colour hair. (you know of course, that dye is only used on fabrics?)
The problem with highlighted hair is that you have different kinds of porosity. That is a big determining factor when colouring or perming hair. What will happen is that the colour pigments you are using in the product will absorb differently into the various kinds of hair you have. So you may get darker deeper shades in the bleached hairs. If it's dark enough, you may not see them. Because the bleached hairs do not have a base of much colour, you may get some off shades, such as green or purple or gray tones only on the hi-lited hairs. You will not get an even colour.
You will also get faster fading from the bleached hairs. That won't show up for some time later. The bleached hair (the hi-lites) are double- or triple-processed -- that is where the real problem comes up. This hair is more damaged than most of the other hairs. In time, they may present you with extensive damage that just cannot be repaired.
Am I saying not to colour over your highlights? Not at all. I am saying, be aware of what you are doing, and of how to process the hair without further damage. There are ways. That is why it is best that you have this performed by a qualified professional hair colourist who has all the training, the skills, the experience and the resources to do this with the utmost care and attention. You do want it to look good, don't you? Judging by what you see on the street, most people really don't care.Is it safe to box dye your hair after previously having salon highlights?
just like everything else it has pros and cons. Now its fine if you dye your hair with a box dye, i have done it a bunch of times the only cons of doing it is your hair will stop growing for a few months and if you mess up you might not like it!
but as long as you dont dye it a bunch of times you should be fine!! =)
Depends on your hair. If you have thin, fragile hair, you might break it off..... If you have thicker, healthy hair it should be fine. Just make sure you leave it on for the right amount of time. And if possible just get a trim afterwards so it will look nice and healthy!
well
it depends i guess
i had blond highlights
and they turned orange
so i put brown coloring over it and they were still very noticeable
i dont think its bad for your hair because u just have higlights your whole head hasnt just been colored
maybe ask a professional
its not bad at all, i was Platinum blonde and i tried to dye dark brown but it came out to a lighter brown
use semi permanent, this way there is no peroxide in it and it will not damage your hair at all
yea its not any worse for your hair than dying it in the first place
