I was always scared to cut my hair but recently thought 'oh sod it' , and had it cut from boob length to a mid length bob (between jaw and shoulders) probably about 10 inches off, and I love it!
It looks so much healthier, saves me time in the morning, easier to wash, my hair doesn't get in the way, trapped in bra straps etc. It also has gotten me noticed and compliments and I feel more stylish!
I've seen a lot of mumsnet threads saying you'll regret cutting your hair and it ages you....in my opinion it's the opposite! Maybe the case if you go very short ie. a pixie, no offence top anyone who does that, it can look amazing! But it wouldn't suit me as I have strong features.
But to cut it a bit shorter, bob etc= would totally recommend it!
