Brassiness

but please please dont use it too much or your hair will have a purple glow lol

schwarzkoff have a purple toner thats used after shampooing, before conditioning, it feels terrible in your hair and your hair feels like a tangled mess but it works like pixie dust and once you wash it out and condition your hair is none the wiser

Ooh should prob mention the Loreal Shine Blonde shampoo is really moisturising too – I`ve found toners/purple shampoos are often too drying on my hair but this one is def not! 🙂

KMS for coloured hair (purple bottle) is fantastic, I have very light blonde coloured hair and it keeps the brassiness away. Is very moisturising too.
Also asked my hairdresser to stay away from caramel blondes (used to have caramel blonde foils, now platinum blonde) as they tend to look brassy very quickly.

I use Loreal Shine Blonde range – keeps my blonde hair looking great – no brassiness at all!

Have you tried shampoo and conditioner that is designed for blonde hair? They tend to have a purple colour through them which usually help neutralise the brassyness.

Or even purchase a toner to put through it every now and then. It has been so long that I have bought hairdye products that I don`t know where sells it these days but I would try a chemist, price attack or something?
