Product description

What it does

Smooth Therapy is Step 2, Realignment, of the Reactive Pro straightening protocol. Built on the LuminAlign System, it optimises light reflection while thermally aligning the hair fibre, on a glyoxylic acid base. The label states it is engineered for blonde and sensitive hair: a violet pigment lifts the reflect while the flat iron seals the realignment.

Smooth Therapy carries the Formaldehyde Free seal and the V-Label International vegan certification on the label, the same as Reactive Pro Shampoo: a decisive claim for a UK client asking whether a straightening service uses formaldehyde.

The label caps ironing for this product at 160 to 190°C, never higher. That ceiling is lower than Piur London's other, higher-heat smoothing line, which is built for non-blonde, chemically resistant hair: the two lines share the same two-step logic, but Smooth Therapy exists specifically to protect the reflect that a higher heat range would compromise.

Key actives, as on the label

  • Glyoxylic Acidthe realignment (straightening) active
  • Silanetriolreinforces the fibre's structure
  • Panthenolconditioning
  • Acid Violet 43the violet pigment behind the Blonde Preservation claim; it works on the reflect, it is not a toner
  • Tamarindus Indica Fruit Extract

When to use it

Immediately after Reactive Pro Shampoo, on hair dried fully, on blonde, highlighted or otherwise sensitised hair booked for a straightening service.

How to use it

  1. Apply evenly in fine strands, keeping 1 to 2cm away from the scalp.
  2. Leave to process for 40 minutes at room temperature.
  3. Rinse until fully removed.
  4. Dry the hair 100 percent.
  5. Flat iron in fine strands, 10 to 15 passes per section, at 160 to 190°C and never higher.

What not to do

  • Professional use only; adult use.
  • Never exceed 190°C. This ceiling is declared on the label; a higher heat range belongs to Piur London's other smoothing line, built for different hair.
  • Keep the application 1 to 2cm away from the scalp.
  • Six-month shelf life: rotate stock and check the batch date before use.
  • Do not shorten or extend the 40-minute pause; do not skip drying fully before ironing.

Piur's flagship system

Smooth

Technical Brazilian smoothing engineered for sleek, formaldehyde-free results.

  • Formaldehyde-free
  • Amino acid + plant keratin
  • 3-4 month retention
  • UK and EU compliant
  • Salon-grade system

Hero ingredient

Amino acids + plant keratin

Piur's signature pairing. Hydrolysed amino acids penetrate the cortex to rebuild internal bonds, while plant-derived keratin reinforces the cuticle and locks in the smoothed alignment. Together they replace the structural role formaldehyde plays in traditional systems, with no regulated aldehydes and full UK and EU compliance.

How to use this line

1

Prep

Cleanse with the ReactivePro clarifying shampoo to lift residue, open the cuticle and prime the fibre for active uptake.

2

Treat

Apply the ReactivePro smoothing treatment strand by strand, let it process, then seal with heat to lock the realignment in.

3

Maintain

Send the client home on sulphate-free shampoo and a weekly bond mask to extend retention across the three to four month window.

Questions about this line

How is Piur Smooth different from traditional Brazilian keratin?
Traditional protocols rely on formaldehyde or methylene glycol to set the smoothing. Piur Smooth uses amino acids and plant keratin to achieve the structural realignment, so the finish reads as sleek and natural without the regulated chemistry.
Which hair types does the Smooth system suit?
The line is engineered for Brazilian, European and mixed-texture hair, from wavy to tight curl patterns. Stylists adjust processing time and tension to leave movement in or push toward a sleeker finish.
How long should clients wait before washing after a Smooth treatment?
We recommend a 48 hour rest before the first wash, and sulphate-free home-care from day one. Following the post-treatment protocol is what protects the three to four month retention window.
