Sarah K La Vie en Rose Brazilian Vegan Protein Smoothing Kit 2x1000ml

The Sarah K Professional Hair La Vie en Rose Brazilian Vegan Protein Kit (2x1000ml) brings together the two products behind the salon smoothing service: the La Vie en Rose Clarifying Shampoo that deep-cleans and prepares the hair, and the Brazilian Vegan Protein that smooths it. Both are 100% vegan and formaldehyde-free, built on a plant-based amino-acid blend instead of animal keratin. Used in sequence, they calm frizz, soften the wave and make hair quicker to style while keeping its natural movement.

A complete vegan, formaldehyde-free smoothing system

This kit is a smoothing system rather than a permanent straightener, and it reaches its result without formaldehyde. The Clarifying Shampoo deep-cleans first, so nothing sits between the fibre and the smoothing that follows; the Brazilian Vegan Protein is then drawn into the clean hair and set with the heat of a flat iron. Its amino acids support the natural protein structure of the hair, so the cuticle lies flatter, frizz settles and the surface feels smoother, with no formaldehyde fumes during the service.

What is in the kit

La Vie en Rose Clarifying Shampoo (1000ml): a vegan deep-cleansing shampoo that clarifies and prepares the hair, so the smoothing meets a clean, even surface from roots to ends.
Brazilian Vegan Protein (1000ml): the vegan, formaldehyde-free smoothing itself, applied strand by strand and sealed in with heat for a softer wave and less frizz.

Key ingredients

Vegan amino-acid protein (Wheat Amino Acids plus a free amino-acid complex): the plant-based alternative to animal keratin, it helps support the natural protein structure of the hair as the smoothing is sealed in with heat.
Arginine: an amino acid that works alongside the blend to support a smoother, more even result through the lengths.
Myrrh Oil (Commiphora Myrrha): a conditioning botanical oil that lends softness and a healthy-looking shine to the finish.
Almond Oil (Prunus Amygdalus Dulcis): a nourishing oil that helps leave the hair soft and supple after the service.

What to expect

After the service, hair looks smoother and more polished, frizz is noticeably reduced and styling becomes faster. This is a smoothing, so expect softer, more manageable hair rather than a poker-straight finish: waves relax and coarser or curlier hair becomes much smoother without losing all of its shape. The flat-iron pass on very thin strands sets the result, and the smoothness eases gradually as it wears.

Who it is for

Stylists who want the complete vegan, formaldehyde-free smoothing system, prep and smoothing, in one kit.
Clients looking to reduce frizz and cut styling time without committing to a permanent straightener.
Anyone who prefers a 100% vegan, plant-based protein option over animal keratin.
Most hair types wanting smoother, softer, more manageable hair with natural movement.

Who it is not for

Anyone expecting a permanent, poker-straight result; this softens and smooths rather than permanently straightens.
At-home users wanting a quick wash-in product; this is a professional, applied service with a flat-iron pass.
Anyone who has not done a patch and strand test, which should always come first.

Professional tip

Clarify thoroughly with the La Vie en Rose Clarifying Shampoo before you smooth, so the Brazilian Vegan Protein meets a clean, even surface from roots to ends. Work in thin sections, keep the product 1 cm off the scalp, and flat-iron on very thin strands so each one is properly set. Sending clients home with a sulfate-free routine helps the smoothness last between washes.

How to use

Wash with the La Vie en Rose Clarifying Shampoo to deep-clean and prepare the hair, then rinse.
On clean hair, apply the Brazilian Vegan Protein strand by strand through the lengths, leaving a 1 cm space from the root.
Let it act for 45 minutes.
Rinse thoroughly until the water runs clear, then dry the hair 100%.
Flat-iron on very thin strands at the temperature set in the professional protocol.

Safety: For professional use, external use only. Always carry out the patch and strand test first (scan the QR code on the bottle). Keep out of reach of children; protect from light, excessive heat and humidity. Avoid contact with eyes, mouth and mucous membranes, and rinse well with water if contact occurs. The Brazilian Vegan Protein contains fragrance allergens (limonene, linalool, alpha-isomethyl ionone) and the preservatives methylchloroisothiazolinone and methylisothiazolinone; discontinue use if sensitisation occurs.

Compatibility

The kit is the complete prep-and-smooth service on its own: clarify with the Clarifying Shampoo, then smooth with the Brazilian Vegan Protein on the clean, dried lengths. Afterwards, the sulfate-free La Vie en Rose shampoo and conditioner keep the result smooth between washes, so prep, smoothing and home-care all work together within the same vegan line.

Built on a vegan amino-acid blend with Myrrh Oil, Almond Oil and Arginine.

Frequently asked questions

Is the kit formaldehyde-free, and how do I use it safely?

Yes. The Brazilian Vegan Protein in this kit states 0% formaldehyde on the label, so it smooths by sealing a vegan amino-acid blend into the hair with heat rather than by releasing formaldehyde. It is still a professional service, so always do the patch and strand test first, keep the product off the scalp, work in a ventilated space and avoid contact with the eyes and mucous membranes.

What is in the kit, and why use the shampoo and protein together?

The kit pairs the La Vie en Rose Clarifying Shampoo (1000ml) with the Brazilian Vegan Protein (1000ml). The shampoo deep-cleans and opens the hair so nothing sits between the fibre and the smoothing; the protein is then applied to the clean hair and set with heat. Used in that order, they give a more even, longer-lasting smooth result than the smoothing on its own.

Can I use it on colored or bleached hair?

It is generally used on colored and bleached hair, but porosity varies, so a strand test first is essential and a slight shift in tone is possible. Where you can, let fresh colour settle before the service, and have your stylist confirm the result on a test strand, especially on lightened or very light blonde hair, before treating the whole head.

How long do the results last?

As a formaldehyde-free vegan smoothing, the result sits on the gentler side and fades gradually, typically lasting around two to three months depending on hair type, how often you wash and aftercare. A sulfate-free home-care routine, such as the La Vie en Rose shampoo and conditioner, helps the smoothness and frizz control last longer between washes.

Is the vegan protein the same as keratin?

It is the plant-based alternative to animal keratin. Instead of animal-derived keratin, it uses wheat amino acids and a free amino-acid complex with arginine to support the natural protein structure of the hair, which is then smoothed in with heat. That is what lets the La Vie en Rose line stay 100% vegan while still giving a protein-style smoothing result.

Can I do this smoothing at home, or is it salon-only?

It is labelled for professional use, and the method is what makes the difference. The hair is clarified, then the protein is applied strand by strand leaving 1 cm from the root, left for 45 minutes, rinsed, dried fully and flat-ironed on very thin strands at the protocol temperature. A stylist manages the sectioning and the right heat, which keeps the result even and long-lasting.
