A keratin treatment is a salon smoothing service that infuses your hair with keratin protein, then seals it in with heat to reduce frizz, add shine, and make hair easier to style for several weeks to months.

Quick Scoop: What does a keratin treatment do?

  • Smooths the hair cuticle so hair looks sleeker and feels softer.
  • Cuts down frizz and puffiness, especially in humidity.
  • Can loosen curls and waves, making hair more manageable but not always pin-straight.
  • Adds shine and can make split ends look temporarily “sealed.”
  • Often shortens blow-dry and styling time by creating a smoother surface.
  • Results usually last around 3–6 months, depending on your hair and how you care for it.

Here’s a simple way to picture it: imagine your hair strands as shingles on a roof; a keratin treatment paints a thin, protective, protein-rich layer over those shingles so they lie flatter, reflect more light, and don’t puff up at the first sign of moisture.
