For those of you that do protective styles and use no/minimal direct heat do you think it has helped you grow and/or retain length. I have been alternating between cornrows, french braids, and twists to keep my ends protected. I have noticed a difference. The last time I flatironed my hair was at the end of January and it was about neck length. After taking down my cornrows 2 days ago my hair was SL. I will continue to do these styles with no heat except for when I dust my ends 1-2 more times this year and dcing once a week. I am a natural 4b and want to be between APL and BSL straightened by May 2010. I just wanted to know from those who have done this if it has helped you retain length or does it end up being more damaging to your hair.
