What it does
Rebonding Shampoo is Step 1, the preparation step, of the Rebonding straightening protocol. Its Deep Cleansing Purifier formula helps remove residual build-up while equalising porosity across the fibre, preparing the cortex to receive the B-Plex System treatment in Step 2, Keraplex. Formaldehyde free and V-Label certified vegan, the same two seals carried by Keraplex, so the full two step service is formaldehyde free from the first rinse.
Key actives (as on the label)
- Hypnea Musciformis Extract, marine algae
- Sargassum Filipendula Extract, marine algae
- Gelidiella Acerosa Extract, marine algae
- Cocamidopropyl Betaine, mild secondary cleanser

When to use it
As the opening step of the Rebonding protocol, immediately before Keraplex, on chemically resistant hair booked for the two step realignment service.
How to use it
- Apply to damp hair.
- Massage the scalp and lengths gently, without rubbing.
- Leave for 2 to 3 minutes.
- Rinse thoroughly with warm water.
- Dry the hair completely before moving to Step 2, Keraplex.
What not to do
- Professional use only, adult use.
- Do not use on damaged or broken skin.
- Do not apply Keraplex while the hair is still damp: dry it 100% first.
The system
Rebonding
Hair type Chemically resistant hair booked for the two step Rebonding protocol, any prior chemical history.
Not for Not sold or positioned as a stand-alone clarifying shampoo; its role is preparing the fibre for Keraplex, not a general wash. Not used on damaged or broken skin.
Rebonding is Piur London's formaldehyde free straightening protocol: it exists for chemically resistant hair carrying volume the client wants brought down, hair with the kind of natural strength that can take an iron up to 230 degrees Celsius.
A glyoxylic acid base realigns the bonds inside the cortex while the flat iron itself completes the thermal seal on the cuticle, the B-Plex System named on the Keraplex label. Deep Cleansing Purifier runs first so the fibre reaches Step 2 with even porosity from root to ends.
In the chair, confirm the hair is chemically resistant rather than blonde, highlighted or sensitised, that calls for Reactive Pro instead, then run Shampoo, dry the hair completely, apply Keraplex 1 to 2cm off the scalp, hold the 40 minute pause at room temperature without shortening it, dry completely again, then iron in fine sections.
The volume comes down and the hair still moves like hair.
Within this page, two products answer the two steps of the same service. Rebonding Shampoo is the preparation step, Deep Cleansing Purifier. Keraplex is the realignment step, B-Plex System, the formaldehyde free active that does the chemical work before the iron seals it in.

Rebonding Shampoo, Deep Cleansing Purifier
2 to 3 minutesRemoves residual build-up and equalises porosity across the fibre, so the Keraplex meets the same cortex from root to ends in Step 2.
Apply to damp hair, massage the scalp and lengths gently without rubbing, rinse thoroughly with warm water, then dry the hair completely before Step 2.
Keraplex, B-Plex System
40 minute pause, then iron 160 to 230 degrees CelsiusGlyoxylic acid realigns the bonds broken inside the cortex while reinforcing the fibre's structure, formaldehyde free.
Apply evenly through the hair, 1 to 2cm off the scalp. Leave for 40 minutes at room temperature, rinse until removed, dry the hair 100% again, then iron in fine sections, 10 to 15 passes per section, at 160 to 230 degrees Celsius depending on the hair's type and resistance.
