I want to put an intensive conditioner on today. I'm not going out for ages so could leave it on for about three hours, but will that make any difference? Does it stop doing anything after 15 minutes? My hair's been heavily highlighted recently and really needs a bit of loving!
While I'm on the subject, can anybody recommend a really, really good conditioner? Don't mind paying £££ if I know it's going to work. (Well, maybe ££.)
