I went to beauty school too.
One thing to remember when using a different product...is to always do a spot test. The directions tell you to do that. I have found even with a product you've always used you can have a reaction to it, so you always need to be careful when using chemicals on your body.
I hope you heal real fast. I had orange hair once, only I'm a brunette.
You may want to be very careful the next time you do your hair with any product...you may have a reaction to that too.
