SOS BTX Elyssa 300G — Intensive Hair Collagen Repair

This product is SOS BTX Elyssa in a 300 g size. Paris Liss repackages it from the original professional Elyssa 1KG format into a neutral 300 g jar. The formula and quantity are identical to the brand's 300 g amount; only the container differs.

SOS BTX Elyssa is a professional restructuring treatment designed to repair, nourish and revitalize dry, brittle, weakened or dull hair.

Elyssa positions this treatment as a hair collagen SOS treatment. Its formula notably contains hydrolyzed keratin and coconut oil to help strengthen the fiber, improve resistance and restore elasticity, softness and shine.

Its disciplining action can also relax and straighten the hair by up to 50% depending on the hair type, while preserving flexibility and natural movement.

Why choose SOS BTX Elyssa?

• Intensive repair: helps restructure dry, brittle and severely weakened hair.
• Hair collagen: professional Elyssa treatment designed to revitalize and strengthen the fiber.
• Elasticity and resistance: improves the flexibility of weakened hair.
• Shine: leaves the hair looking brighter and silkier.
• Disciplining action: helps reduce frizz and can straighten by up to 50%.
• Nourishment: nourishes the hair fiber and improves its feel.

Which hair types is it suitable for?

SOS BTX Elyssa is suitable for all hair types and is especially appropriate for hair that is:

• dry or dehydrated;
• brittle or weakened;
• dull and lacking shine;
• colored or bleached;
• sensitized by chemical treatments or heated styling tools;
• curly, coily, kinky, wavy or straight and in need of greater discipline.

What result can you expect?

After the treatment, hair appears softer, more flexible, shinier and more disciplined. The fiber gains elasticity and resistance while frizz is better controlled.

According to Elyssa, SOS BTX can also straighten the hair by up to 50%. The level of relaxation achieved depends on the hair type, its initial condition and the protocol used.

Is it a straightening treatment?

SOS BTX Elyssa is first and foremost an intensive restructuring treatment.

However, it also has a smoothing and disciplining action that can reach approximately 50%. It can therefore soften and relax the hair, but its main purpose remains repair, nourishment and revitalization of the hair fiber.

Directions for use

1. Wash the hair thoroughly.
2. Dry the hair to approximately 80%.
3. Divide the hair into 4 sections.
4. Apply SOS BTX evenly through the lengths, avoiding the roots and scalp.
5. Leave on for approximately 30 minutes.
6. Rinse thoroughly to remove the product.
7. Dry the hair completely, then blow-dry.
8. Finish by flat ironing the entire head to complete and seal the treatment.

The flat-iron temperature and number of passes must always be adapted to the hair type, resistance and condition.

How often should SOS BTX be used?

The effects can generally last around 4 to 6 weeks depending on the hair type, condition and maintenance routine.

On severely weakened hair, several treatments may be performed at closer intervals before gradually spacing out applications.

300G size repackaged by Paris Liss

This 300 g size is repackaged by Paris Liss from the original professional Elyssa 1KG jar.

It therefore contains the same product and formula as the professional Elyssa 1KG size. Only the packaging changes: the treatment is transferred into a neutral 300 g jar to offer a more compact size for lower-volume needs.

The container received is therefore not an official Elyssa 300G jar. The product inside comes directly from the original professional Elyssa 1KG format.

To prolong the softness, flexibility and shine achieved after SOS BTX Elyssa, choose a gentle and suitable maintenance routine.

Krystal Care Sulfate-Free Shampoo 500 ml — ideal for gently cleansing the hair after the treatment.

Precautions

Perform a patch or strand test before use. Avoid contact with the eyes and scalp. Do not apply to an irritated or damaged scalp. Follow the manufacturer's recommendations and adapt the protocol to the condition of the hair.
