    Use creams or milks on damp hair before blow-drying, and sprays or foams on dry hair before hot tools.
  • Never skip protection
    Apply heat protectant every time you use heat to prevent cumulative damage.
  • Avoid excessive heat
    Even with protection, keeping tools at moderate temperatures helps maintain long-term hair health.
