You can get a toner called "UNRED" it is navy blue. you can add it to hair colour or shampoo or conditioner.....it does tone the brass.
I had two hair disasters this summer....
1. the Brasilian Keratin Treatment
OMg not for blondes !!!! My hair turned like Yellow--bright orangy yellow---icky !!!! was terrible and so much work to get npot yellow....surprised any hair is left on my head
2. The blowdryer at the GYM
I had a bad experince with hair getting caught in a dryer years ago so I am pretty careful--usually and only use my own blowdryer
babyliss pro--so good
BUT I was ina hurry and took a fast shower at he gym with my hair in a ponytail...got a little wet and had a meeting that was kind of important so I used the little blowdryer attatched to the wall ---my hair got stuck and ripped out.....so now it looks like bangs/fringe in the BACK of my head I spend every morning trying to disguise this mishap and it grows so slowly...
See your hair could be worse !!
