Biolage Scalp Sync Oil-Balancing Scalp Serum, 1.6 fl oz — Vegan, Fermented Tea Blend, Lightweight

Biolage Scalp Sync Oil Balancing Serum is a lightweight, leave-in concentrate that absorbs and reduces excess scalp oil between washes for a fresher-feeling scalp.

This vegan, cruelty-free serum uses a micro-dosed fermented tea blend to target oily roots without weighing hair down. Designed for use on wash days, the formula helps keep sebum from traveling down strands so hair looks and feels cleaner for longer. It pairs with the Scalp Sync shampoo and conditioner to create a full scalp-care routine, and the dropwise application makes it easy to treat only the areas that need balancing.

How does this serum control oil without drying out my scalp?

The serum is formulated to absorb excess surface oil while leaving the scalp’s natural moisture barrier intact. The fermented tea concentrate works at the scalp level rather than stripping oils across the entire hair shaft, so you get balance instead of dryness. Short application and targeted dosing prevent overuse and maintain scalp comfort.

• Micro-dosed fermented tea blend to absorb surface oil
• Leave-in formula avoids over-stripping natural lipids
• Apply only on scalp areas to preserve hair hydration

When and how should I apply the Scalp Sync Oil Balancing Serum?

Apply on wash days after shampooing and conditioning while hair is towel-dried. Section hair to expose the scalp, place a drop of serum every inch along the roots, then massage for about one minute to distribute the product. Finish by drying hair as you normally would; no rinse is required.

• Use immediately after towel-drying on wash days
• Dropwise application every inch along the scalp
• Massage one minute, then style or dry as usual

Will this work for all hair types and styling routines?

The lightweight texture and targeted dosing make it suitable for most hair types, especially those prone to oily roots. It won’t add noticeable weight or residue when used as directed, and it integrates with color-, texture-, and style-focused regimens. For best results, use it as part of the Scalp Sync system for balanced cleansing and conditioning.

• Light formula fits fine to thick hair without heavy buildup
• Compatible with color-treated and styled hair
• Pairs with Scalp Sync shampoo and conditioner for routine use

What key ingredients are in the serum and what do they do?

The signature ingredient is a fermented tea blend concentrate that blends antioxidant-rich black tea with soothing green tea derivatives. This concentrate helps absorb surface oil and supports scalp comfort without harsh surfactants. The formula is vegan and cruelty-free, crafted for targeted, leave-in use.

• Fermented tea blend concentrate for oil absorption and antioxidant support
• Minimal, lightweight carrier ingredients to avoid residue
• Vegan, cruelty-free formulation for conscious shoppers

Who is this for: Biolage Scalp Sync Oil Balancing Serum is ideal for people who experience greasy roots between washes and want a lightweight, targeted solution. It suits those who prefer leave-in scalp treatments over clarifying shampoos, anyone following color-safe or vegan haircare, and shoppers who want a precise, dropwise product to maintain freshness without daily washing.
