Why Choose Sulphate-Free Shampoo?


Traditional shampoos often contain sulphates like Sodium Lauryl Sulphate (SLS), which create lather but can strip hair of its natural moisture. A sulfate-free shampoo provides a gentler cleanse, making it ideal for dry, damaged, or sensitive hair.

Best Sulphate-Free Shampoo for Colour-Treated Hair


Sulphate-free formulas help preserve hair colour by preventing premature fading. If you’ve dyed your hair, choosing a colour-safe, sulphate-free shampoo ensures long-lasting vibrancy while keeping your hair nourished and soft.

Is Sulphate-Free Shampoo Better for Your Scalp?


If you suffer from dryness, irritation, or sensitivity, switching to an SLS-free shampoo can soothe your scalp and reduce itchiness or flaking. Many sulphate-free options contain botanical extracts, aloe vera, and essential oils to support scalp health.

Hydrating Benefits of Sulphate-Free Haircare


Sulphate-free shampoos retain moisture, making them perfect for curly, coily, and frizzy hair types that need extra hydration. Ingredients like coconut oil, argan oil, and shea butter deeply nourish the hair and reduce breakage.

Best Sulphate-Free Shampoo for Oily Hair


A common myth is that sulphate-free shampoos don’t cleanse as well as traditional formulas. However, many clarifying sulphate-free shampoos use natural ingredients like tea tree oil and charcoal to remove excess oil while maintaining scalp balance.

Sulphate-Free vs. Silicone-Free: What’s the Difference?


While sulphate-free shampoos avoid harsh cleansing agents, silicone-free shampoos eliminate build-up from synthetic conditioning agents. If you want lightweight, natural-feeling hair, look for a shampoo that is both sulphate-free and silicone-free.
