Function of Beauty Wavy Hair Shampoo — Sulfate-Free, Nude Peach Scent for Lightweight, Anti-Frizz Wave Definition

Function of Beauty Wavy Hair Shampoo is a lightweight, sulfate-free cleanser formulated with fermented rice water to enhance, strengthen, and define natural type 2 waves without weighing hair down.

This shampoo is designed specifically for wavy hair patterns that need gentle cleansing, frizz control, and improved elasticity. The formula avoids sulfates and parabens, uses fermented rice water as a key botanical, and pairs best with the matching Wavy Hair Conditioner to amplify softness and definition. It’s scented with a signature Nude Peach fragrance that blends peach nectar, lemon, and jasmine for a refreshing shower experience.

How does this shampoo support natural waves without stripping them?

The sulfate-free base cleanses hair and scalp while preserving natural oils that help waves form and hold. Fermented rice water contributes proteins and amino acids that can help strengthen the hair shaft and improve elasticity, supporting wave shape over time. This results in cleaner, more resilient waves that maintain movement rather than becoming lifeless.

• Gentle surfactants remove dirt and build-up without harsh stripping
• Fermented rice water for strengthening and elasticity support
• Lightweight formula avoids weighing waves down
• Sulfate- and paraben-free to protect natural oils

Will this help reduce frizz and improve definition on humid days?

The shampoo helps reduce frizz by smoothing the hair surface and maintaining moisture balance so strands clump into natural waves more readily. While no shampoo alone eliminates frizz, pairing it with the Wavy Hair Conditioner and styling products designed for waves amplifies the anti-frizz effect. The overall routine improves definition and manageability in variable humidity.

• Maintains moisture to prevent excessive frizz from dryness
• Works with conditioners and serums to lock in wave shape
• Light scent prevents heavy residue that can weigh hair
• Daily-use formulation supports consistent styling results

How should I use this shampoo for best wavy results?

Apply a quarter-sized amount to wet hair, focusing on the scalp and roots for cleansing, then gently work the lather through lengths to avoid tangling. Rinse thoroughly and follow with the Wavy Hair Conditioner for added softness and detangling. For enhanced wave formation, scrunch with a microfiber towel or diffuse on low heat after applying leave-in products.

• Use daily or as needed depending on scalp oiliness and styling
• Concentrate on the scalp, then let the rinse cleanse lengths
• Pair with conditioner and lightweight styling creams or gels
• Finish with scrunching or gentle diffusion for boost

Is this shampoo compatible with colored or chemically treated wavy hair?

The formula is designed to be gentle and non-stripping, making it suitable for most color- and chemically-treated wavy hair. Because it’s free of sulfates and parabens and focuses on strengthening ingredients, it helps protect treated hair’s integrity when used as part of a caring routine. For freshly colored or chemically processed hair, follow stylist guidance and consider less frequent washing to preserve color and treatment longevity.

• Sulfate-free to help protect hair color and treatments
• Strengthening rice water supports fragile strands after treatments
• Works best with color-safe conditioners and leave-ins
• Adjust wash frequency based on hair’s response
