@Munzi, You're better off talking to your stylist than listening to readers. After all she is an expert! It's not about the layers; it's about how they're cut.
Katarina:Layers don't work!!!I totally agree with You.I have fine hair,I know this as a fact.There is a great article about it at the beautyeditor website!
I feel like layers can be a bad idea for thin hair. They can make the lower layer look like tails due to the lack of volume of hair. A 'V' cut bluntly in the back with only face-framing layers is a better alternative in my opinion. :)
