The Protein Repair

For hair that bleach and heat got to first

Protein refilled weekly, topped up daily, sealed always. The honest system for hair that cannot heal but can be rebuilt.

Softer, stronger-feeling hair after treatment one. The full rhythm shows at 4 to 6 weeks.

This is for you if…

  • Bleached, coloured or heat-styled hair that snaps in the brush
  • Ends that feel like straw and act like static
  • Wet hair that stretches and breaks instead of bouncing back
  • The salon says 'trim it' and you want a second opinion first
  • 'Repair' shampoos that repaired nothing

What’s going on

Hair is dead protein. No blood supply, no healing. Bleach and heat do not wound it like skin. They dissolve pieces of its structure and lift its outer scales. That is why 'repair' shampoos disappoint. Nothing regrows. What truly works is refilling — putting proteins back into the gaps — and sealing the scales down on top.

The system: refill with the weekly treatment. Top up with the daily leave-in. Seal with oil. One skill to learn: the protein and moisture balance. Hair that snaps needs protein. Hair gone stiff and straw-like from too much protein needs a moisture week. Your hair tells you. This protocol teaches you to listen.

What causes it

  • Bleach. It dissolves protein bonds on purpose. Lightening IS controlled damage.
  • Heat over 180 degrees. It melts the scale edges a little every pass.
  • Wet brushing. Hair is weakest wet. Rough detangling snaps what bleach loosened.
  • Sun and salt water. Summer's quiet gift to autumn's straw.
  • Towel scrubbing. Rubbing on lifted scales turns frizz into breakage.

The plan at a glance

Weekly

  1. Refill — the protein treatment on towel-dried hair, 10 to 15 minutes, rinse.

Every wash

  1. Top up — the leave-in ampoule through damp lengths.
  2. Seal — two drops of oil, mid-length to ends.

Always

  1. Oil before any heat. Heat under 180. Wide-tooth comb on wet hair.

The steps

Refill (weekly)

Weekly

Protein back into the strand, where bleach took it out

A protein treatment fills the gaps that bleach, colour and heat left inside the hair. It rebuilds density and snap-resistance from within. For a while.

Why it matters: Hair is dead protein. It cannot heal, only be refilled. These treatments are that refill. Real, and temporary. That is why the weekly rhythm matters more than any single use.

How to do it: On clean, towel-dried hair. Soak the damaged lengths. Leave 10 to 15 minutes, a shower cap helps. Rinse well. Weekly for damaged hair. Fortnightly once it steadies.

Elizavecca's CER-100 is the famous strong one, remarkable for the price. Aromatica's Quinoa mask is the plant-protein route with a softer finish.

Boost (leave-in, between refills)

Morning & evening

Daily backup between the weekly rebuilds

A leave-in protein ampoule tops up the refill work daily. Light enough not to stiffen. Steady enough to hold the strand between treatment days.

Why it matters: Weekly treatments do the heavy lifting. The leave-in keeps the result. Damaged hair loses its refilled protein with every wash. The boost slows the leak.

How to do it: A pump or two through damp lengths after washing. Comb through, style as usual. Skip the roots.

Aromatica's Quinoa ampoule is the daily-friendly leave-in. Elizavecca's Ion Injection is the stronger, occasional option for badly damaged lengths.

Seal

Morning & evening

Gloss on top, moisture locked underneath

A hair oil smooths the outer scales flat over the protein work. It seals moisture in, calms frizz, and takes the heat so your hair does not.

Why it matters: The outer scales are the strand's roof tiles. Damage lifts them. Oil lays them down. That is why sealed hair shines, and stops snagging in the brush.

How to do it: Two or three drops warmed between palms. Pressed through damp or dry lengths. Mid-length to ends, never roots. Before heat styling, it doubles as the shield layer.

Elizavecca's CER-100 oil continues the protein story. Aromatica's Ritual Oil is the botanical, lovely-smelling finish.

What to expect

  • Treatment one — denser, smoother hair the same evening. Protein refills speak up fast.
  • Weeks 2–4 — less snapping in the brush. Less hair on the floor. Ends that hold together.
  • Weeks 4–6 — the rhythm settles. Weekly refills stretch to fortnightly. Truly split ends still need the trim. Protein fills gaps, not absences.

Do & don’t

✓ Do

Learn the strand testWet a hair, stretch gently. Snaps at once: needs moisture. Stretches and stays: needs protein.
Squeeze water out with a soft clothNever scrub.
Oil before every heat sessionThe oil is cheaper than the hair.
Silk or satin pillowcases help if frizz is a warNight rubbing counts too.

✕ Don’t

Do not protein-treat more than weeklyOverloaded hair goes stiff. The balance is the skill.
Do not brush soaking-wet bleached hairFingers and a wide comb, ends first.
Do not run irons above 180 degreesNothing above that is worth the cost.
Do not expect any product to rescue truly split endsRefill what remains. Trim what is gone.
