by mumsy, do you mean cut all at one length at the back? so it looks like a mum, but also a 7 year olds haircut?
i love the ends of my hair to be.. i dono how to describe it exactly, but kind of grown out? i hate when my hair is blunt at the end, all one length, like someones just chopped it. a few months ago a hairdresser did that to my hair and i went beserrrrrrrrrrrrrrrrrk.
i recently used the 'free haircut with this bottle' promotion on the herbal essences shampoos and took a photo of a haircut i wanted, and was SOO SPECIFIC with the hairdresser, i got exactly what i wanted.
i personally don't think you can look much worse just because you've had your hair chopped from back length to shoulder length.. get your hands on that free haircut from herbal essences thing (or just get the money for) another haircut and be specific with them etc.... and take a photo!!!!
