Biolage Volume Boost Conditioner for Fine Hair, 33.8 fl oz — Weightless Moisture & Root Lift

Biolage Volume Boost Conditioner is a lightweight conditioner that detangles fine hair while adding shine, weightless moisture, and root lift through micro-dosed soy protein and polymers.

Formulated to support fine, limp, or color-treated hair, this conditioner balances hydration and volume so strands look fuller without feeling heavy. The formula uses micro-filtered soy protein to help retain moisture and polymers that create lift from the root, delivering manageability, gloss, and a fuller appearance. It rinses clean and works best when paired with the Volume Boost Shampoo and Root Lift Spray in the same collection.

How does this conditioner add volume without weighing down fine hair?

The conditioner combines carefully measured soy protein with lightweight polymers that coat strands without heavy oils or silicones. These ingredients create subtle structural support along the hair shaft and at the root, producing visible lift and body while maintaining natural softness.

• Micro-dosed soy protein strengthens and retains moisture without stiffness.
• Lightweight polymers provide root lift and fuller-looking strands.
• Fast-rinse formula prevents residue that can make fine hair limp.

Will it detangle and keep hair soft after washing?

Yes—this conditioner is designed to smooth the cuticle and reduce tangles so combing is easier after the shower. The lightweight conditioning agents improve slip and manageability while preserving movement and natural shine.

• Detangles wet hair for quicker, gentler brushing.
• Maintains natural softness and flexible texture, avoiding heaviness.
• Suitable for color-treated hair when used as directed.

How should I use it for best results?

Apply to clean, wet hair after shampooing—ideally following Biolage Volume Boost Shampoo. Work through mid-lengths to ends and leave in for 1–3 minutes before rinsing thoroughly; concentrate product at the roots only if extra lift is needed.

• Use a quarter-sized amount for shoulder-length fine hair; adjust as needed.
• Leave 1–3 minutes to allow soy protein and polymers to activate.
• Pair with Volume Boost Shampoo and Root Lift Spray for maximum fuller-looking results.

Is the formula suitable for sensitive or color-treated hair?

The conditioner is free from parabens and formulated to be gentle on color-treated hair while providing conditioning and volume. As with any product, perform a patch test if you have scalp sensitivities or consult a stylist for personalized advice.

• Paraben-free and vegan-friendly formulation.
• Gentle enough for color-treated hair when used as directed.
• Avoid direct contact with irritated scalps; discontinue use if irritation occurs.

Who is this for: Biolage Volume Boost Conditioner is aimed at people with fine, flat, or limp hair who want a boost of body without sacrificing softness or shine. It’s a practical choice for color-treated hair and anyone looking to build root lift and manageability into their routine while keeping formulas lightweight and salon-grade.
