I'm rubbish with all things style and beauty so need some help please. I have a black tie event in July. I'm rubbish with my hair so I'm planning to get a "red carpet blow out" from a hairdressers near me. I need some advice though please. A blow out doesn't include a cut does it? My hair is roughly in the style it needs to be in by then, but will need a trim. It's bra strap length. Ideally I'd like a bit more length so I'm keen to avoid extra hair cuts. What would you do between now and then? A trim soon and a trim just before my blow out appointment? Does it need a trim just before? I'm so rubbish at things like this.
