fyi: It's not very serious that would warrant emergency service but it is something I need your advice on as I have to take my asthma puffer due to wheezing HELP!!!

I want to know about formaldehyde. The carcinogenic cancer properties is scary and wondering whether it is regulated in the hair industry? If it is then I can be reassured that the quantity the hairstylist used was not strong and that I may just be sensitive to it at first.

My hairstylist added Keratin treatment to my curly hair. It was my first time, and so my eyes were burning, I began to wheeze and cough. The smell is still there for the second day.. I'm concerned.. but should I not and treat it as a normal issue that just needs to build tolerance?...
