Buying Guide: Keratin Deep Conditioners
- What is your hair type? Fine hair benefits from lighter formulas to avoid weighing down hair, while dry or damaged hair may tolerate richer masks.
- Are you color-treated? Look for color-safe formulas that preserve vibrancy while delivering moisture.
- Activity and heat exposure: If you heat style often, prioritize strong frizz control and keratin stabilization.
- Ingredient priorities: Keratin concentration, along with natural oils (coconut, argan, jojoba) and biotin, can influence shine, softness, and detangling.
- Fragrance sensitivity: Some products include vanilla or botanical extracts; choose fragrance-free options if needed.
- Application frequency: Begin with 1–2 uses per week and adjust based on how hair responds (oiliness, heaviness, or hydration level).
