Have spent about 2 painful years growing out a short layered crop to a chin length bob, no layers as I found that the layers were going all sticky-outy and driving me mad. But now I have this smooth bob I feel it looks so mumsy. Looks okay when first washed but not for long. My hair is very thick with a slight wave, but it will blow dry smooth. I hate the stacked bob look short at the back. I;m worried if I have layers cut back in it will go all fly away and unmanageable again. I don't want to go short and choppy again either! Any ideas? Thanks!
