Jaclyn Smith from Jo Hansford Salon says:
"The best way to keep brassiness at bay. is to buy the right home care products i.e. shampoo, conditioner & masques to keep your blonde tones looking beautiful. Your hairdresser will make a recommendation during your appointment depending on the colour result you are after, the products they use & the condition of your hair.
Products you can consider include a silver shampoo or conditioner that will help keeping that kind of redish, rusty, brasiness at bay. L’Oréal Professionnel serie expert Silver Shampoo is a great example of this.
But of course protecting your hair early is better than having to deal with it when it’s too late and to protect against brassiness we recommend seeing the same colourist every time you go to the salon. Your colourist can get to know your hair & recommend the right tones for you to give the correct neutralisation of brassy tones & ensure you get the longeivtiy you want from your colour. They can also make recommendations on treatments & products to keep your blonde looking fabulous."
