When should you use a sulfate-free shampoo?

When your hair is dry, frizzy, colored, smoothed, keratin-treated, or chemically processed, the best product to use is a sulfate-free shampoo. It is a hair cleansing gel that does not de-oil the hair and leaves the hair soft, smooth and manageable. It can also be used by individuals who have sensitive scalp or by those who do not wash their hair regularly. When your hair becomes rough, dull or loses shine after normal washing, using a sulfate-free shampoo will help make it feel and look better.
