Cair Fortifying Hair Serum

Hyaluronic Acid + Caffeine Complex + Fermented Raspberry Extract

A scalp-focused treatment designed to support a healthy hair environment while helping improve hydration, comfort, and vitality. Rich in skincare-inspired active ingredients and prebiome technology, this alcohol-free fortifying serum helps rebalance the scalp ecosystem while respecting the microbiome. The lightweight formula works to hydrate, energize, and strengthen the scalp, leaving hair looking healthier, shinier, and more resilient from the very first use.

100 ml | Approximately 2 months of use

Benefits:
  • Helps support scalp health and vitality.
  • Hydrates and comforts the scalp.
  • Helps strengthen the appearance of hair.
  • Supports a balanced scalp microbiome.
  • Gently exfoliates to promote a healthier scalp environment.
  • Helps improve the appearance of shine and radiance.
  • Alcohol-free formula suitable for sensitive scalps.
  • Free from silicone, artificial colouring, sulfate-based surfactants, and alcohol.
How to Use:
  • Step 1: Apply directly to the scalp before shampooing using the directional spray applicator.
  • Step 2: Section the hair and distribute evenly across the entire scalp.
  • Step 3: Gently massage to help emulsify with sebum and support penetration of the active ingredients.
  • Step 4: Leave on for 10–15 minutes before shampooing.
  • Step 5: For an intensive treatment, apply 1–2 times weekly and leave on overnight before rinsing and shampooing.
Loshen & Crem's Recommendation:

Think of this as skincare for your scalp. Ideal for anyone experiencing dryness, imbalance, dullness, or looking to support healthier-looking hair from the root.
