Yea... This maybe wasn't a friendly thing to do. Her hair may look the same to you but give it a good 3 months before the roots start snapping and breaking and the ends are visibly thin. By the way getting a texturizer didnt help me love my natural hair, I had to transition from that for a year and I only have myself to blame. I would be pretty salty if a friend had done that to me... Maybe not even want to talk to them.
