Biolage Smooth Proof Conditioner 8 fl oz — Lightweight Frizz Control with Camellia Oil & Glycerin

Biolage Smooth Proof Conditioner is a lightweight, camellia oil and glycerin–infused formula that detangles, hydrates and helps smooth frizz-prone hair without weighing it down.

Designed for everyday use, this 8 fl oz conditioner from Biolage Smooth Proof targets unruly, humid-prone strands with micro-dosed camellia oil and glycerin to replenish moisture and reduce static. The vegan, paraben-free formula is color-safe and made to sit light on hair while improving manageability and surface shine. Packaging uses recycled plastic, reflecting a lower-impact choice for routine hair care.

How does this conditioner reduce frizz and fight humidity?

The formula combines camellia oil for surface-smoothing and glycerin to attract and retain moisture inside the hair fiber. These ingredients work together to create a smoother cuticle, reduce flyaways and help hair resist humidity-related puffiness.

• Camellia oil smooths hair surface and increases shine
• Glycerin hydrates by drawing moisture into strands
• Micro-dosed formula avoids weighing fine hair down
• Helps control static for a sleeker finish

Will this conditioner detangle without leaving hair greasy?

Yes — the lightweight conditioning base slips through wet strands to ease combing while rinsing cleanly to avoid heavy buildup. It restores softness and manageability without an oily residue, making it suitable for most hair types that need frizz control.

• Instant detangling for easier comb-through after shampoo
• Rinses away clean to keep volume and movement
• Formulated to be non-greasy and not weigh hair down

How should I use Biolage Smooth Proof Conditioner for best results?

Apply to clean, wet hair after shampooing; leave in for one to three minutes and rinse thoroughly. For a full smoothing routine, pair it with Biolage Smooth Proof Shampoo and follow with Smooth Proof Serum or Leave-In Cream if extra control is needed.

• Apply to mid-lengths and ends, avoiding heavy roots
• 1–3 minutes leave-in time before rinsing for optimal hydration
• Layer with smoothing serum or leave-in for long-lasting control

What are the formula details and sustainability features?

The conditioner is vegan, free from parabens, mineral oil, silicones and artificial colorants, and is color-safe. The tube is produced using a high percentage of recycled plastic to reduce environmental impact in packaging.

• Vegan and free of parabens, silicones, mineral oils and colorants
• Color-safe formulation suitable for treated hair
• Tube made with approximately 73% recycled plastic
