Caring for Damaged Hair Between Washes

Heat, colour, and everyday brushing all add up. A few simple changes between washes can keep damaged hair stronger for longer.

1 min read

Most hair damage doesn't happen in the shower. It happens in the days between, from heat tools, tight styles, sun, and the friction of brushing and sleeping. The good news is that those days are also where you can make the biggest difference.

Signs your hair needs more support

  • Ends that split or feel rough no matter how often you trim

  • Frizz that shows up even on low-humidity days

  • Strands that snap when you brush instead of stretching

  • Colour that fades faster than it used to

What Strand Strengthening is for

Strand Strengthening is a 6-peptide hair treatment made for damaged, split, and frizzy hair. You work it through damp hair after washing, and it's designed to leave strands feeling smoother and more resilient.

Treat the lengths like fabric: gentle handling now saves you from repairs later.

A between-wash routine

  1. Detangle from the ends up. Start at the bottom and work toward the roots so knots don't tighten.

  2. Turn the heat down. If you use hot tools, lower the temperature and always use a heat protectant.

  3. Refresh the lengths. On day two or three, smooth a small amount of treatment through the mid-lengths and ends.

  4. Protect at night. A loose braid or a silk pillowcase cuts down on friction while you sleep.

Small changes, repeated often, do more for damaged hair than any single fix.
