Buying Guide
Key purchase considerations
- Sulfate and paraben content: Post-keratin care benefits from sulfate- and paraben-free formulas to maintain moisture and the smooth results of treatments.
- Color-treated hair compatibility: If color is part of your routine, choose shampoos labeled color-safe to prevent fading and maintain vibrancy.
- Protein balance: Keratin-based shampoos add protein to hair. For sensitive scalps or very fine hair, balance protein with hydrating ingredients to avoid buildup or weighing hair down.
- Moisture and oils: Look for nourishing components like argan oil, silk protein, or vitamin B5 to help maintain moisture and reduce frizz between keratin sessions.
- Cruelty-free and ethical considerations: Several products emphasize no animal testing, aligning with consumer preferences for responsible brands.
- Hair type fit: Curly, dry, or damaged hair often benefits from stronger strengthening formulas, while fine or oily hair may require lighter alternatives.
