Sarah K La Vie en Rose Brazilian Vegan Protein Kit 3x100ml

The Sarah K La Vie en Rose Brazilian Vegan Protein Kit (3x100ml) is the complete three-step salon smoothing service in one trial-size kit: a Clarifying Shampoo that preps the hair, the Brazilian Vegan Protein that smooths it, and a Restorative Neutralizer that seals the result. All three are 100% vegan and formaldehyde-free, built on a plant-based amino-acid blend instead of animal keratin, calming frizz and leaving hair smoother, softer and quicker to style with its natural movement kept.

A complete vegan, formaldehyde-free 3-step smoothing system

This kit is a smoothing system rather than a permanent straightener, and it works without formaldehyde. The Clarifying Shampoo deep-cleans first, so nothing sits between the fibre and the smoothing. The Brazilian Vegan Protein is then set into the clean hair with a flat iron; its amino acids support the hair's natural protein structure, so the cuticle lies flatter, frizz settles and the surface feels smoother. The Restorative Neutralizer seals the cuticle for a glossy finish. Because the protein is plant-based and formaldehyde-free, the line stays 100% vegan with no formaldehyde fumes during the service.

What is in the kit

Step 01 -- Clarifying Shampoo (100ml): a vegan deep-cleansing shampoo with aloe vera that preps the hair, so the smoothing meets a clean, even surface.
Step 02 -- Brazilian Vegan Protein (100ml): the vegan, formaldehyde-free smoothing itself, applied strand by strand and sealed in with heat for a softer wave and less frizz.
Step 03 -- Restorative Neutralizer (100ml): a pH 3.5-4.0 finisher with Amazonian butters and oils that seals the cuticle for a smooth, glossy finish.

Key ingredients

Vegan amino-acid protein (Wheat Amino Acids plus a free amino-acid complex): the plant-based alternative to animal keratin, supporting the hair's protein structure as the smoothing is sealed with heat.
Arginine: an amino acid that works alongside the blend for a smoother, more even result through the lengths.
Myrrh Oil (Commiphora Myrrha) and Almond Oil (Prunus Amygdalus Dulcis): conditioning oils that lend softness and shine.
Murumuru Butter, Tucuma Oil and Cupuacu Butter: Amazonian butters and oils that seal and nourish.

What to expect

After the service, hair looks smoother and more polished, frizz is noticeably reduced and styling is 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 its shape. The flat-iron passes and the neutralizer set the result and its shine, and the smoothness eases gradually.

Who it is for

Stylists who want the complete vegan, formaldehyde-free three-step smoothing in one trial-size 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 flat-iron work.
Anyone who has not carried out the patch and strand test, which should always come first.

Professional tip

Clarify thoroughly before you smooth, so the Brazilian Vegan Protein meets a clean, even surface. Work in thin sections, keep the product 1 cm off the scalp, and flat-iron very thin strands so each is set before the neutralizer. A sulfate-free home routine helps the smoothness last.

How to use

Step 01 -- Clarify. Wash the hair with the Clarifying Shampoo, repeating as many times as needed to remove all residue. On the last wash, leave it on for 3 minutes, then rinse thoroughly.
Step 02 -- Smooth. On clean hair, apply the Brazilian Vegan Protein strand by strand, leaving a 1 cm space from the root. Let it act 45 minutes, rinse thoroughly, dry 100%, then flat-iron on very thin strands.
Step 03 -- Neutralize. Apply the Restorative Neutralizer to damp hair, covering all the lengths. Leave 5 to 15 minutes, then rinse with water only. Flat-iron again, 8 to 12 passes, more on the roots and less on the tips, until smooth and glossy.

Safety: For professional, 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, heat and humidity. Avoid contact with eyes, mouth and mucous membranes; rinse well with water if contact occurs. The Brazilian Vegan Protein and the Restorative Neutralizer contain fragrance allergens (limonene, linalool, alpha-isomethyl ionone) and the preservatives methylchloroisothiazolinone and methylisothiazolinone; discontinue use if sensitisation occurs.

Compatibility

The kit is the complete service on its own: clarify, smooth, then seal with the Restorative Neutralizer. Afterwards, a sulfate-free La Vie en Rose home-care routine keeps the result smooth between washes. Everything sits in the same vegan line, so all four steps work together.

Frequently asked questions

Is the kit formaldehyde-free?

Yes. The kit is labelled 'formaldehyde-free' on the box and on all three bottles, so it smooths by sealing a vegan amino-acid blend into the hair with heat rather than by releasing formaldehyde. There are no formaldehyde fumes during the service, though it is still a professional application, so good ventilation and the usual salon care always apply.

How do I use the kit safely, and who should avoid it?

Carry out a patch and strand test first (scan the QR code on the bottle). It is for professional use: work in a ventilated space, keep the product off the scalp, and avoid contact with the eyes, mouth and mucous membranes. The formulas contain fragrance allergens (limonene, linalool, alpha-isomethyl ionone) and MCI/MI preservatives, so discontinue use if any sensitivity appears.

How long do the results last?

As a formaldehyde-free vegan smoothing, the result sits on the gentler side and fades gradually rather than dropping all at once. How long it lasts varies with your hair type, how often you wash and your 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.

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.

What is in the kit, and what does each of the three steps do?

The kit has three 100ml steps. Step 01, the Clarifying Shampoo, deep-cleans and prepares the hair. Step 02, the Brazilian Vegan Protein, is the smoothing, applied strand by strand and sealed with heat. Step 03, the Restorative Neutralizer, seals the cuticle after the smoothing for a smooth, glossy, longer-lasting finish.

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.
