Aaaawwwwww, it stinks. I am pre-sleeve. My hair is mid-booty and thick and curly and I suffer with finding a ponytail holder to go around twice. Once is not enough,twice is too much.
I am also a cosmetologist. I have approx. 15-20 clients that have weightloss surgery. I FINALLY convinced approx 1/2 of them to cut their hair due to how thin it was. Those women now have their thick hair back! Cutting it helped to put it in a trendy hairstyle, keep a shape to it so it can grow back out again. so yes, it appears thicker and trendy.
The few that opted to just let it hang, looks more thin than before. It's really only because the new hair that is growing back in hasn't been enough to "fill in" where it had all come out.
All of them have their hair growing back, it's only what they do with it in the "in-between" that makes it better.
So, yes, rock your new 'do and love it with all the weight pouring off. The hair comes back. Eat your Protein and take your supplements.
Hope this helps.
