Biolage Smooth Proof Conditioner — Lightweight Frizz Control, 33.8 fl oz Vegan Hydration

Biolage Smooth Proof Conditioner is a lightweight, vegan conditioner formulated with camellia oil and glycerin to detangle, hydrate and reduce frizz for smoother, shinier hair.

Designed by a professional salon brand, this Smooth Proof conditioner delivers focused moisture without heaviness. Micro-dosed camellia oil helps slip through each strand while glycerin draws in hydration, making hair easier to comb and less prone to static and flyaways. The formula is paraben-, silicone-, mineral oil- and colorant-free, and the tube uses recycled plastic, aligning performance with cleaner‑beauty preferences.

How does this conditioner tame frizz and flyaways?

The conditioner smooths the hair surface and helps balance moisture so strands are less likely to swell and form frizz in humid conditions. Lightweight emollients create slip for easier detangling, while humectants attract moisture to maintain softness.

• Camellia oil micro-dosed to smooth the cuticle
• Glycerin hydrates without weighing hair down
• Creates slip for quick detangling and less breakage
• Formulated to reduce static and surface roughness

Will it work on my hair type and color-treated hair?

Biolage Smooth Proof is formulated for all hair types, from fine to coarse, and is color-safe so it won’t strip salon color when used as directed. Because the conditioner is lightweight, it can be used by people who want smoothing benefits without a heavy residue.

• Suitable for fine, medium and thick textures
• Safe for color-treated hair when rinsed thoroughly
• Vegan formula avoids animal-derived ingredients
• Free from parabens, silicones and mineral oils

How do I use it for best results in my routine?

Apply after shampooing to clean, wet hair, leaving the conditioner on for one to three minutes before rinsing. For persistent frizz or extra smoothing, combine with the matching Smooth Proof shampoo and finish with Smooth Proof serum or leave-in cream.

• Apply to wet hair after shampooing; leave 1–3 minutes
• Rinse thoroughly to avoid buildup on finer hair types
• Layer with Smooth Proof styling products for longer-lasting control
• Use regularly to maintain softness and manageability
