My highlights have become orange color.

Do you know where to buy products that can make the color less orange?

There are many brands but I don't know if they are available in Singapore.

The shampoos and conditioners are usually purple or blue color and on the bottle it will say it's for blonde or white hair or brassy hair. Something like that.

Also, where to buy Loreal Castings? I don't see it at Watson's. I heard that because it is semi-permanent, we can apply it to our hair to make it less orange? Is this true?

I appreciate your help! Thanks!
