Using sulfate free shampoos that is free of Sodium Lauryl Sulfate (SLS), like Schwarzkopf's Color freeze shampoo can be the best thing you can do for your hair.
Why, you ask? Because SLS, which is a powerful detergent that cuts through grease and makes our soap and shampoo foamy, is also used in products like dish soap detergent, Lysol spray, most laundry detergents, and even Clorox Toilet Wands.
Despite the fact that SLS cut grease and lathers our hair, it does not clean our head safely.
Now, Director Monsoon Salon and Spa and Vogue Colorist of the year Rod Anker believes that to look after our color and scalp we should avoid shampoos that have SLS if you have color in your hair and if you want the vibrancy to last.
