Wow...I'm sorry. Your grandmother is supposed to be supportive..
I bet your hair is gorgeous though.
My family was never really like that...idk. I had a relaxer from 3 til the age of 15 when I stopped wearing them. I have been natural for about 2 years and 7 months, but relaxer free for 3.5 years. I have mostly 4a hair. When I had it pulled back last Christmas my grandmother, mother, brother and boyfriend at the time, were all like "you have waves?" I'm like "yeah...?" Lmao. I thought was funny. But one time my grandmother asked if it was hard to comb...(she has a relaxer and thin hair). I told her not really. That was the one and only time she asked about it.
