Sarah K La Vie en Rose Brazilian Vegan Protein Smoothing 1000ml

The Sarah K Professional Hair La Vie en Rose Brazilian Vegan Protein (1000ml) is a professional, formaldehyde-free smoothing built on a 100% vegan protein blend. Instead of animal keratin, it works with wheat amino acids, a free amino-acid complex and arginine, alongside Myrrh Oil and Almond Oil, to smooth the hair and calm frizz through the lengths. Applied strand by strand and sealed in with heat, it softens the wave, reduces frizz and leaves hair easier to manage and quicker to style, while keeping its natural movement.

A vegan, formaldehyde-free smoothing

This is a smoothing rather than a permanent straightener, and it reaches its result without formaldehyde. Where older Brazilian systems leaned on harsh chemistry, this formula relies on a vegan amino-acid blend that is drawn into the hair and then set with the heat of a flat iron. The amino acids support the natural protein structure of the hair, so the cuticle lies flatter, frizz settles and the surface feels smoother. Because the protein is plant-based, the line is 100% vegan, and because there is no formaldehyde, there are no formaldehyde fumes during the service.

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 day to day. 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 step on very thin strands is what sets the result, and the smoothness eases gradually as it wears rather than dropping all at once.

Who it is for

Stylists who want to offer a vegan, formaldehyde-free smoothing in the salon.
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 step.
Anyone who has not done a patch and strand test, which should always come first.

Professional tip

For the most even result, start on hair that has been deep-cleaned with the La Vie en Rose Clarifying Shampoo, so the blend 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

On clean hair, apply the product 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.
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. This product contains fragrance allergens (limonene, linalool, alpha-isomethyl ionone) and the preservatives methylchloroisothiazolinone and methylisothiazolinone; discontinue use if sensitisation occurs.

Compatibility

Use the La Vie en Rose Clarifying Shampoo first to deep-clean and prepare the hair, then apply the Brazilian Vegan Protein smoothing on the clean, dried lengths. Afterwards, the sulfate-free La Vie en Rose shampoo and conditioner keep the result looking smooth between washes. All three sit within the same La Vie en Rose vegan smoothing line, so they are designed to work together from prep to home-care.

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

Frequently asked questions

Is the Brazilian Vegan Protein formaldehyde-free, and how do I use it safely?

Yes. The label states 0% formaldehyde, 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.

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 results sit on the gentler side and fade gradually, typically lasting around two to three months depending on 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.

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.

Will it make my hair completely straight?

It is a smoothing rather than a permanent straightener. It reduces frizz, relaxes the wave and makes hair easier to manage and quicker to style, while keeping natural movement. Coarser or curlier hair becomes noticeably smoother rather than poker-straight, and the flat-iron step on very thin strands is what sets how sleek the final result looks.

Can I do this smoothing at home?

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