Thanks for the comments girls.
I'm thinking I'll keep it straight, and now I've found out how to get my hair curling nicely I'll just have it curly when I either get time or for special occasions.
Luckily I dont need to go near straightners and can manage to get straight with a blowdryer which means less damage.
The other thing I noticed is it is much easier to assess the condition of the hair when it's straight. My stylist only used two products which I then purchased and I think the good result has a lot to do with them. They must be why it's guarding itself so well aginst humidity.
As for the colour; my highlights are slowly dissapearing and the colour my stylist put on them matches my own perfectly considering she only covered the highlights you can see no difference between my regrowth which is about 6 inches and the ends.
