My hair is shoulder length and very fine/thin. I just had it coloured (blonde highlights) and cut and I'm happy with it for the first hour after I've styled it but after that it just gets tangled easily and as soon as i step outside and the wind gets to it it looks awful. I get the same colour and cut done every 12 weeks or so. I use a deep conditioner twice a week, washed every day or every other day with shampoo for coloured hair. What can i do to make it sleek and shiny and stay that way throughout the day? Its been like this for years and i feel like getting it cut and coloured is a waste of money when day to day i really hate how it looks.
