In-Residencia Hydrating Shampoo San Margo

In-Residencia is not just a shampoo—it’s a return to balance.

A lightweight, microbiome-friendly formula designed to cleanse without disruption, restoring a sense of equilibrium to both scalp and hair. Where traditional cleansing can feel stripping, reactive, or overly aggressive, this is a more refined approach—one that works with the scalp rather than against it.

It recognises that true hair health begins at the root. That how you cleanse determines not only how your hair looks, but how it behaves over time—its resilience, its texture, its ability to maintain strength and vitality.

Each use becomes less about removing, and more about recalibrating. Gently lifting away buildup while maintaining the scalp’s natural environment, allowing it to function as it should. The result is a clean that feels calm, balanced, and uninterrupted—where nothing is overcorrected, and everything is supported.

Over time, this consistency creates a shift. Hair that feels lighter, more responsive. A scalp that feels stable, less reactive. A routine that no longer disrupts—but restores.

Product Details

What it does

A refined approach to cleansing—focused on balance, not disruption:

  • Gently removes buildup — lifting away oil, impurities, and environmental residue without over-stripping
  • Maintains scalp equilibrium — supports the natural microbiome for long-term stability
  • Hydrates as it cleanses — preserving moisture within both scalp and hair
  • Improves manageability — leaving hair feeling lighter, softer, and more responsive
  • Reduces reactivity — ideal for sensitive, stressed, or hormonally shifting scalps

The result is a clean that feels calm, balanced, and sustained—never compromised.

The formulation

A high-performance blend of hydrating and balancing actives:

  • Fermented probiotics to support a healthy scalp environment
  • Cationic hyaluronic acid for smoothness and hydration
  • Panthenol (Vitamin B5) to strengthen and condition

Fragrance-free and dermatologically tested, it’s created for ongoing use—including sensitive scalps and periods of hormonal change—without irritation or disruption.

The experience

Soft lather. Clean, without excess.

A silky, fluid texture that lifts away daily buildup—oil, impurities, environmental residue—while maintaining the scalp’s natural balance.

There’s no heaviness, no residue—just a clean that feels calm, weightless, and uninterrupted. Designed to integrate seamlessly into your routine, it transforms washing from a task into a moment of reset.

Why it’s different
  • Microbiome-first cleansing — supports balance at the scalp level
  • Gentle but effective — removes buildup without stripping
  • Weightless hydration — nourishes without heaviness
  • Fragrance-free clarity — nothing unnecessary, nothing reactive

Because the way you cleanse determines everything that follows.
