I love to braid my hair, and I've been doing so for about a year and my hair looks amazing. I am noticing (ever so sightly) thinning on both sides of my hair line (diagonal to the corner of my eye) so I've decided to give my hair a break by wearing my wig with cornrows underneath. I can't do the wig thing for too long, and now that it's winter I really don't want to leave my hair out in the cold. My hairdresser is good about my hairline, so I know it's not that the braids are tight...but how can I continue braiding without damaging my hairline?
