Yeah that's what I thought, because I use to live there for 6 months, my hair grew, and my aunties hair is bra strap length now. Her hair grows fast, I am a Nigerian, I just don't know why my hair isn't growing fast, my mom's hair is short too, but all my aunties, cousins, grandparents, have long hair, it's their humidity too. Because it is hot along there. My relatives live in Lagos, Port Harcourt, Anambra, and Rivers state.
