Explanation of Key Groups

Surfactants

Primary and co-surfactants (e.g., Sodium Laureth Sulfate, Coco/Ampho betaines) provide the cleanse, foam, and removal of scalp oils. Mild co-surfactants help soften the feel and improve tolerance.

Clay Minerals

Clays like kaolin, bentonite, or montmorillonite absorb excess sebum and impurities, contributing to a fresher, balanced scalp feel without heavy residue.

Actives

Ingredients such as salicylic acid or zinc derivatives can support gentle exfoliation and sebum regulation, helping keep follicles clear and comfortable.

Humectants

Water-binding agents (e.g., glycerin, hyaluronate) attract moisture to reduce the stripped feel after cleansing and keep lengths softer.

Safety Notes & Allergens

  • Fragrance allergens (e.g., linalool, geraniol, coumarin) may be present if fragrance is listed.
  • Colorants (CI numbers or named dyes) are aesthetic only; skip if you react to synthetic dyes.
  • Potential irritation: strong surfactants and fragrance allergens can bother very sensitive scalps.
  • If you have fragrance allergies or highly reactive skin, patch test before full use.

Summary

Best suited for users seeking a clear, balanced cleanse. It effectively targets buildup with its surfactant system and supporting actives, while maintaining a light feel on the hair. Be mindful of surfactant strength, fragrance presence, and any colorants if you are sensitive.

Who is this product good for?

  • ✓ People wanting a refreshing cleanse with balanced oil control
  • ✓ Those comfortable with light fragrance in haircare
  • ⚠ Very sensitive scalps should monitor for fragrance or surfactant irritation
