Biolage Scalp Sync Calming Shampoo — 33.8 fl oz, soothes dry sensitive scalps with fermented tea & glycolic acid

Biolage Scalp Sync Calming Shampoo is a gentle, vegan formula that cleanses and soothes dry, sensitive scalps while delivering weightless hydration.

This shampoo uses a fermented tea blend and micro‑dosed filtered glycolic acid to remove impurities, rebalance the scalp, and help prevent the tight, dry feeling that follows inadequate moisture. The formula is free of parabens and safe for color-treated hair, offering a spa-like wash experience in a large 33.8 fl oz size that’s designed to last. Lightweight conditioning leaves hair manageable without buildup, while the product’s clinical-inspired ingredients focus on scalp comfort rather than heavy moisturizers.

How does this shampoo soothe a dry, sensitive scalp?

Scalp Sync Calming Shampoo combines gentle surfactants with a fermented tea blend and a micro-dosed filtered glycolic acid to cleanse without stripping natural oils. The ingredients work together to reduce sensations of tightness by restoring surface moisture and removing residue that can irritate skin.

• Fermented tea blend helps condition and calm the scalp surface.
• Micro-dosed glycolic acid assists in removing buildup without irritation.
• Light, non-greasy hydration prevents the feeling of tightness after washing.

Will it work on color-treated hair and how often should I use it?

Yes—this formulation is safe for color-treated hair and is designed for regular use. For ongoing scalp comfort and balanced moisture, many users incorporate it into their routine two to three times weekly or more often if needed, adjusting based on how the scalp responds.

• Color-safe formula preserves color vibrancy.
• Large 33.8 fl oz size supports frequent use over time.
• Frequency can be tailored—common use is 2–3 times per week.

What sensory and performance differences should I expect during wash day?

The shampoo creates a gentle lather that rinses clean, leaving hair feeling refreshed and lightweight rather than weighed down. Many people notice immediate reduction in dryness and scalp tightness, plus lasting hydration that can support comfort between washes.

• Gentle foaming action lifts oil and debris without heavy residue.
• Weightless conditioning improves manageability and softness.
• Hydration that supports scalp comfort for up to several days, depending on individual needs.

How does this product fit into a scalp-care routine?

Scalp Sync Calming Shampoo pairs with other products in the Scalp Sync system—like the Purifying Scalp Concentrate and Universal Conditioner—to create a targeted regimen. Use the shampoo as the cleansing step, follow with a conditioner or treatment from the range for added moisture or clarifying effects.

• Use as the first cleansing step in a multi-product scalp routine.
• Combine with Scalp Sync Purifying Scalp Concentrate for targeted treatments.
• Finish with Universal Conditioner for balanced hydration and detangling.
