From Ballsy to Bald
Let's face it.....some subjects are just plain boring. But most subjects can be made at least slightly interesting by the right teacher. It might be cocky, but I will make a science nerd out of you eventually. :-)
Whether a nerd or average commoner, some chemistry knowledge is needed when working with chemicals to avoid disaster. Beauty school is very time consuming so it is easy to stay focused and absorbed it what is going on in class. You will find that after you have already passed you exam, that your knowledge will shortly after be put to use.
Most women love to change their hair drastically, at least sometimes. There are certain changes that you have to avoid though or wait awhile to do. Particularly if you have relaxed your hair and decide you want to convert to a "Jerry Curl" or thio relaxer. Yes, I know. I see you rolling your eyes as you think to yourself, who actually still wears those? Well there is always somebody.
Bad advice circulates everyday and even hair dressers have been known to be the ones giving it. To avoid losing all of this important information somewhere in the back of your mind, I am posting a video showing the chemical reaction of putting a thio relaxer (perm) over sodium hydroxide relaxer.
There are clients that will insist that they know more than you and at times you can have them sign a release form and perform the service anyway. Well this is not one of those times. You will probably get sued and for a lot if you perform this service. So here is a demonstration of what really happens when you overlap these two chemicals together. https://www.youtube.com/watch?v=KuzGyW0dfGk&feature=player_detailpage
