ok, I went to the hairdressers saying that a few years ago because I was sick of wearing my waist long hair in a bun basically Every. Day.

but unfortunately the hairdresser's idea of something different which is "quick and easy" to do in the mornings was a very flattering style which took about 20mins in the evenings and another 20-30 minutes every morning to do, plus a small fortune to buy the product and get the maintenance trim every 6-8 weeks ...

so after about 6 months, it was shoulder length, and I went to a different hair dresser, explained the issue of what had happened last time - and had almost an identical repeat performance, except the new cut took only 15 mins at night - but still 20-30 mins in the morning - and not too much $$ for product ...

not sure how much the maintenance cuts would have been - because I never went.

so 2.5 years on, I have finally grown my hair back to its original length, and you know what? It's in a bum almost every day.

all that being said, maybe you'll have more luck?
