Buying Guide
What to look for when choosing a keratin shampoo and conditioner:
- Hair type and goal: For frizz control, prioritize smoothing formulas; for damage repair, seek keratin and strengthening ingredients like collagen and silk proteins.
- Free-from considerations: If sensitive to sulfates or parabens, select sulfate-free and paraben-free options.
- Color-treated hair: If color-treated, check for color-safe claims to protect vibrancy.
- Ingredient quality: Favor formulas with nourishing oils (argan, etc.) and proteins that reinforce hair structure.
- Size and value: Larger bottles may offer better long-term value; consider your routine to avoid waste.
FAQ
- Do keratin shampoos weigh hair down? Some formulas are lightweight and offer conditioning without heaviness. Look for light, sulfate-free options if this is a concern.
