Buying Guide: Key Considerations For These Shampoos

  • Hair type and porosity: Curly or textured hair with high porosity benefits from keratin-infused, moisture-balanced formulas.
  • Heat protection: Look for products that include heat-protective ingredients to minimize styling damage.
  • Frizz control vs. cleansing strength: Some shampoos focus on smoothing; others emphasize clarifying action. Choose based on buildup and scalp needs.
  • Color-treated compatibility: If hair is color-treated, select sulfate-free formulas to preserve color.
  • Conditioner pairing: Keratin or smoothing shampoos typically perform best with a complementary conditioner or mask.
  • Maintenance routine: Keratin-based products can require a consistent regimen for best results; adjust frequency accordingly.
