I had my lap band surgery on Feb. 18th (4 weeks ago yesterday) Last Friday, March, 14th, I had my hair cut and became quite distressed when my hairdresser found 2 bald spots that she said were probably caused by a lack of proper vitamins. I had been taking vitamins, but somewhat sporadically. I'll make it a regular routine now!!! Has anyone else experienced this, and will the hair come back?
