Biolage Volume Boost Conditioner for Fine Hair — 33.8 oz Lightweight Root Lift & Shine

Biolage Volume Boost Conditioner is a lightweight conditioner formulated with micro-dosed soy protein and polymers to detangle, add shine, and create root lift for fine hair without weighing it down.

Lightweight fine hair needs conditioning that restores softness and slip while preserving body. This 33.8 oz (1,000 mL / 400 mL variant reference) salon-grade conditioner from Biolage uses micro-filtered soy protein and polymers to deliver moisture and lift in precise amounts, helping fine and color-treated hair feel smooth, manageable, and fuller-looking. It’s designed to slot into a volume-focused routine alongside the Volume Boost Shampoo and Root Lift Spray.

How does this conditioner add volume without making hair heavy?

The formula includes micro-dosed polymers that form a light support structure on strands and at the root, creating lift without the buildup heavier creams cause. Micro-filtered soy protein helps retain moisture inside the hair shaft so you get softness without loss of body.

• Polymers deposit minimal, weightless texture for root lift.
• Soy protein preserves hydration without adding density.
• Rinses cleanly to avoid residue that flattens fine hair.

Will this conditioner work with color-treated hair?

Yes — the gentle, lightweight formulation is suitable for color-treated hair and focuses on maintaining softness and shine while supporting volume. It avoids heavy occlusive ingredients that can accelerate color fade by causing product buildup.

• Formulated to condition while protecting surface shine.
• Weightless finish reduces need for extra styling products.
• Compatible with Biolage color- and volume-friendly routines.

How should I use it to get the best lift and manageability?

Apply to clean, wet hair after shampooing, concentrating on mid-lengths and ends and using a light amount at the roots if needed. Leave in for 1–3 minutes to let the micro-filtered soy protein and polymers work, then rinse thoroughly and style as usual for added body and slip.

• Use after Volume Boost Shampoo for complementary action.
• Apply sparingly at the roots to preserve lift; focus more on lengths.
• Rinse after 1–3 minutes for best balance of moisture and volume.

What tangible results can I expect after regular use?

Consistent use typically means easier detangling, improved shine, and a perceptible lift at the root area without added weight. The conditioner aims to maintain fine hair’s natural softness while giving styling a fuller starting point.

• Smoother, more manageable hair that brushes easily.
• Noticeable root lift and overall fuller appearance.
• Maintainable shine that doesn’t compromise volume.

Who is this for: Biolage Volume Boost Conditioner is made for people with fine or limp hair who want lightweight hydration, easier detangling, and natural-looking lift. It’s also suitable for color-treated hair and those who prefer salon-quality botanical-based formulations as part of a volume-enhancing routine.
