Biolage Smooth Proof Shampoo 13.5 fl oz — Sulfate-Free Frizz Control with Camellia Oil & Glycerin

Biolage Smooth Proof Shampoo is a gentle, plant-powered cleansing formula that tames frizz, adds shine, and moisturizes hair using camellia oil and glycerin.

Formulated for hair that resists smoothness, this sulfate-free shampoo removes dirt and buildup while depositing lightweight nourishment to help strands lie flat and reflect light. The vegan, paraben-free blend focuses on moisture balance and slip so wet hair detangles easily and styling stays sleeker under humidity.

How does this shampoo reduce frizz and flyaways?

The formula uses camellia oil to smooth the hair surface and glycerin to retain moisture, creating a smoother cuticle and reducing static. It helps each strand resist humidity-driven swelling so the hair looks sleeker and feels softer after rinsing.

• Camellia oil: smooths and enhances natural shine
• Glycerin: binds moisture for lasting softness
• Sulfate-free cleansing: removes buildup without stripping oils
• Lightweight texture: avoids weighing hair down

Will Smooth Proof Shampoo work on all frizzy hair types?

Yes—the shampoo’s balanced hydration and smoothing actives suit a range of textures from wavy to coily. It won’t flatten naturally voluminous hair but will make strands more manageable while preserving movement.

• Safe for color-treated hair: gentle, non-stripping formula
• Effective on humidity-prone hair: builds a protective, smoothing layer
• Pairs with conditioners and leave-ins for stronger results

How should I use it for the best results?

Apply to wet hair, massage into a lather focusing on the scalp, then rinse thoroughly; repeat if needed. Follow with Biolage Smooth Proof Conditioner and finish with the serum or leave-in cream to lock in smoothness and boost shine.

• Step 1: Wet hair thoroughly; apply a quarter-sized amount
• Step 2: Lather at roots and glide through lengths
• Step 3: Rinse, condition, and style with smoothing products
