Hi geeks I've popped over from nail geeks sorry to crash but need some advice and thought what better place to ask ..... I always curl my hair with straightners usually but want bigger curls, I got some heated rollers and I'm hoping someone could advise me how to put them in I've watched a couple of vids on u tube and have tried them out, I'm guessing bigger rollers give bigger curls but do I roll under or over and should I place them flat on top and sideways at the sides?? Once again sorry to ask as it's only for personal use but any advice would be hugely appreciated xxxxx
