Am I the only one that faints and throws up when I get my hair cut?

Ever since I was little my mom would be the one to cut my hair since she’s a licensed hairdresser, but I would get lightheaded, dizzy, and sometimes even faint. The last time I cut my hair was in December and I got lightheaded and even threw up. I searched up what it could be and it’s apparently a condition called hair- grooming syncope. It could give you seizure-like symptoms and includes being lightheaded, fainting, and nausea. It affects kids ages 5-13, but I’m 18. I just want to know if anyone else experiences this.
