I've visited Just Cuts in Maroubra Junction twice this year, just for a basic trim each time.
On the positive side, they are a no-fuss salon who are ok with very basic requests. You don't need to make an appointment, there's no pressure to buy products, they don't chatter at you incessantly (which I find annoying and uncomfortable), they do the job fast, and they are super cheap.
However, there's a lot I don't like. For a start, they use their own brand of hair products which I don't feel comfortable using at all. I usually wash my hair first then go in with wet hair. Also, they don't seem to have the equipment or advanced skills required for a great style cut and colour. I only ever get a basic trim, and even that is just satisfactory. It doesn't seem to last as long as when I get a trim elsewhere. I guess they have time restrictions because they don't seem to pay much attention to detail.
As a student I really can't afford to go to an expensive salon every time, so I I alternate and go to just cuts every second time, just to avoid split ends. It's ok for that but I wouldn't recommend it for anything else.

Approximate cost: $26.00
