Sulfate-Free Shampoos

Sulfate-free shampoos are gentle cleansing formulas made without harsh detergents such as SLS (Sodium Lauryl Sulfate) or SLES (Sodium Laureth Sulfate). These shampoos cleanse the hair and scalp without stripping natural oils, making them ideal for dry, sensitive, curly or colour-treated hair. They help maintain hydration, reduce irritation and support long-term hair health.

Our sulfate-free shampoo collection includes hydrating, colour-safe, curl-friendly and everyday gentle cleansing options. These shampoos pair well with categories such as Organic & Natural Shampoo and Damaged Hair Treatments & Products to support gentle cleansing routines and hair repair.

What are sulfate-free shampoos?

Sulfate-free shampoos are cleansing products formulated without sulfates, which are strong detergents commonly used to create lather. Without these ingredients, the shampoos produce a softer foam while still effectively removing dirt, oil and product buildup. They are designed to preserve the hair’s natural moisture barrier and reduce dryness.

They are especially recommended for sensitive scalps and chemically treated hair.

What are sulfate-free shampoos used for?

These shampoos are used to cleanse the hair gently while preventing the dryness and irritation that some people experience with traditional sulfate-based formulas. They help maintain softness, shine and elasticity without stripping essential oils.

They are popular among individuals with curly, frizzy, fragile or recently coloured hair.
