Nair and other similar products don't work for me at all. They don't remove the hair! I don't get it!

I used to be an avid waxer because my mom is. She wanted me to get into waxing too. But I switched to shaving and I like it way more.
Hair type: Mostly 3C, medium porosity to high porosity depending on the day, dense, fluffy, dry, tangly!
