I am newly natural and I have not been using heat but its getting cold and I cannot wet my hair as much as I have been doing due to health concerns. Do you think it would be ok if I flat ironed no less than every 2 weeks for the winter months and then go back to using no heat in the Spring and not stunt my growth? I dont have to blow dry it because I dont have to have it bone straight because it will be in a bun. Are there any ladies that do this natural or not and have maintained the health of their hair?
