Yes, Friday I Went To Get My Hair Cut And

Yes, Friday I went to get my hair cut and I was feeling a little nauseous. When I entered the salon there was a strong ammonia smell from the hair coloring my hairstylist was using. After about ten minutes I wasn't feeling to good and I stood up and got dizzy and passed out and vomited. I was rushed to the hospital and had a number of tests and was released within a few hours. Could the strong ammonia smell or whatever the chemical smell was,mother reason for me passing out ?
