Biolage Hydra Source Scalp & Hair Serum, 3 fl oz — Lightweight Aloe + Hyaluronic Hydration for Dry Scalp & Color-Treated Hair

If your scalp feels tight and your strands look dry, this vegan, silicone- and paraben-free serum offers an at-home hydration boost designed for sensitive and color-treated hair. The fast-absorbing texture delivers moisture without greasiness or weight, supporting the scalp’s moisture barrier while smoothing and softening hair from root to tip.

How quickly will I notice hydration after applying the serum?

The formula absorbs rapidly and gives an immediate sense of nourishment to the scalp and hair strands. Many users report a non-greasy, refreshed feel right after application and improved suppleness with continued use.

• Ultra-light water-based texture that sinks in fast
• Micro-filtered aloe vera to soothe and calm
• Fermented hyaluronic acid for sustained moisture retention

Can this serum help a sensitive or color-treated scalp?

Yes — the gentle composition is formulated without silicones, parabens, or animal ingredients, reducing the risk of irritation while remaining safe for color-treated hair. It focuses on restoring hydration rather than adding heavy film or buildup.

• Vegan and cruelty-free formulation
• Free of parabens and silicones to minimize residue
• Designed for compatibility with color-treated and delicate scalps

What is the best way to use this serum in my routine?

Apply to a clean, dry or damp scalp and distribute along the hairline and partings; massage gently to encourage absorption. You can use it as a targeted scalp treatment before styling or as part of a weekly moisture routine to refresh dry areas.

• Use small doses focused on dry patches and roots
• Massage into scalp to support the moisture barrier and circulation
• Pair with hydrating shampoo and conditioner for enhanced results

How does the serum keep hair feeling light rather than weighed down?

The product combines a micro-dosed hydrating concentrate with a water-forward delivery system so moisture is replenished without coating strands. That balance helps maintain natural movement and a clean feel while delivering lasting hydration.

• Water-based vehicle prevents heaviness
• Micro-dosing approach targets hydration where needed
• Leaves hair soft and touchable, not sticky or oily

It’s a practical choice for people with sensitive or colored hair who want a non-greasy, vegan option to restore moisture and improve hair softness and manageability.
