What I personally discovered during my working with hair experience was that there are many tips which are not put out there on Google, or even on the instructions found in the packaging of the hair product itself. Just like someone who learns mechanic in theory and the one who learns it practically at his uncle’s garage.
The theory guy is capable of naming each and every spare part in a car, and he knows exactly where each goes by books. But the practical guy had his hands dirty and learned everything from scratch, so therefore I would like you to be judge who is more experienced than the other. My whole point is that I had a privilege to practically learn by experience and through getting my hands dirty, how to handle these strong hair chemicals.
