Whether you are blonde, brunette, or a raven haired gal, BRASS HAPPENS, and it happens to the best of us. Hair dye has a lot of different and vibrant colors: red, blue, yellow, ect. Combine those colors with the normal process and boom... you've got brassy hair. So...How do we fix that? There are a couple things you can do to prevent brass. 1) You can use color reviving gloss. It adds mega shine and helps close the hair cuticle to prevent fading 2) Watch the environment..yes I said the ENVIRONMENT, like salt water, chlorine, or UV rays. They hurt your hair by drying out your hair, stripping out the natural oils your hair produces.
