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
