Do you really HAVE to do the skin allergy test before coloring your hair?

Even if I have used the same brand before?

Do you really HAVE to do the skin allergy test before coloring your hair?
It is just for them in case you get an allergic reaction so you cannot sue them as they told you so ! (and yes, I would do it even if you had the same brand before, they seem to constantly change the formula or different colours have different ingrediences etc)
Reply:I've never done it and my head is still attached, but it's not a bad idea. Even if you'e used that dye before, you can develop an allergy to it.
Reply:Good question!





Well I've dyed my hair about 7 or 8 times and im only 16 years old! I went from black to brown to blonde, then red, then brown etc!...and to be honest, I never did the skin allergy tests!





I mean, I know you should, but I guess I kind of knew that I wasn't going to be allergic to hair dyes, even though I always use different hair color brands!





So the answer to your question is YES, don't do what I did, because you never know, you may be allergic to a specific ingredient that one of the hair color brands have!





So don't take the risk!





Hope this helped! bye =)
Reply:I have never done the test and have never had a problem. I think it is just a safety thing for the company. If something does go wrong they told you to test it first. Kind of like the McDonald's cautions contents may be hot on their coffee cup. Just a warning
