MONDAY HAIRCARE Smooth Shampoo for Frizz-Prone Hair — 798 mL, Wheat Protein & Avocado Oil, Sulfate-Free

MONDAY HAIRCARE SMOOTH Shampoo is a frizz-fighting, sulfate- and paraben-free formula with wheat protein and avocado oil designed to smooth, nourish, and boost shine for unruly hair.

Formulated for curly, wavy, and frizz-prone hair, this 798 mL bottle combines active wheat protein with naturally-derived avocado oil to help retain moisture and create a protective, glossy finish. The shampoo is pH balanced, dermatologically tested, and certified cruelty-free by Leaping Bunny and PETA, while being free from sulfates and parabens. Its gentle surfactants and conditioning actives make it suitable for regular use without stripping natural oils.

How does SMOOTH Shampoo reduce frizz without weighing hair down?

The shampoo uses wheat protein to help bind and hold moisture within the hair fiber while avocado oil deposits lightweight lipids that smooth the cuticle. Instead of heavy silicones, the formula relies on humectant and emollient balance so hair feels softer without becoming flat.

• Wheat protein helps lock in hydration for reduced flyaways.
• Avocado oil forms a light protective layer to enhance shine.
• Sulfate-free cleansing preserves natural oils and curl pattern.
• pH-balanced formula keeps cuticles smoother after rinse.

Will SMOOTH work on colored, curly, or fine hair?

Yes—its gentle surfactants and no-paraben, no-sulfate formulation make it safe for most hair types, including colored and chemically-treated hair. For fine hair, use a small amount concentrated at the roots and mid-lengths to avoid excess buildup; for thicker or tighter curls, apply generously to ensure even distribution.

• Safe for color-treated hair thanks to mild cleansing agents.
• Adjust amount based on hair density—less for fine hair, more for full curls.
• Dermatologically tested to minimize scalp irritation risk.
• Works as part of a routine with conditioner and styling products for best results.

How should I use this shampoo for best results?

Wet hair thoroughly, apply a nickel-to-quarter sized amount depending on hair length and thickness, and massage into the scalp and lengths until you see a light lather. Rinse completely and follow with a compatible conditioner or leave-in product to lock in smoothing benefits.

• Use warm water to open the cuticle for deeper cleansing.
• Massage scalp for 30–60 seconds to distribute wheat protein evenly.
• Rinse well and pair with a MONDAY HAIRCARE conditioner for added hydration.
• For best frizz control, finish with a cold-water rinse to help seal the cuticle.

What ethical and safety standards does this shampoo meet?

MONDAY HAIRCARE SMOOTH Shampoo meets multiple consumer and ethical standards: it is Leaping Bunny approved and PETA certified as cruelty-free, formulated without parabens and sulfates, pH balanced, and dermatologically tested. The packaging is recyclable, supporting a lower environmental impact compared with non-recyclable containers.

• Leaping Bunny and PETA cruelty-free certifications.
• Free from parabens and sulfates for gentler daily use.
• Dermatologically tested to help reduce irritation risk.
• Recyclable bottle encourages sustainable disposal.

Who is this for: MONDAY HAIRCARE SMOOTH Shampoo is ideal for people with frizz-prone, curly, or wavy hair seeking softer texture and extra shine without heavy silicones or harsh sulfates. It’s also appropriate for those with color-treated or chemically-styled hair who want a gentle, ethically-made cleanser that supports smoothing and moisture retention.
