The Valquer French Straightening Kit is a complete professional kit designed for a single use, offering an advanced thermodynamic treatment to achieve straighter, smoother, and more manageable hair for 4 to 6 months. Developed specifically for hair salons and hair care professionals, this advanced system works without damaging or breaking the hair fibre structure, efficiently controlling volume and eliminating frizz to provide a smooth and glossy finish.
Technology and Performance
This safe and effective thermodynamic treatment combines a light base of purified water that prepares the hair fibre to receive structural nutrients. The formula contains vegetable Keratin and Phytokeratin, an extract rich in plant amino acids derived from corn, wheat, and soy, which repair, strengthen, and reinforce the hair structure from within, increasing flexibility, hydration, and natural shine. Hyaluronic Acid complements this action with deep hydration and protection of the hair structure. The kit includes the Pre-Treatment Shampoo, which has a basic pH that gently opens the cuticle to facilitate the absorption of active ingredients, and the Post-Straightening Mask with Panthenol (Vitamin B5), a humectant that deeply moisturises, improves manageability, and conditions damaged hair.

Does not interfere with colouring or highlighting processes, with a recommended interval of at least 2 weeks between the two treatments.
Significantly improves manageability and detangling without causing a heavy hair effect.
Compatible with hair health protocols: if the SBS treatment is desired, it should always be carried out a couple of weeks after the French Straightening, ensuring that the straightened hair is properly nourished and regenerated.
Expert Tip
As this is a professional kit configured for a single use, this pack ensures strict dosage control and maximum technical effectiveness in the salon. For salon professionals, immediately after completing the mechanical straightening process, it is recommended to dampen the hair and apply the Post-Treatment Mask, then blow-dry for 5 minutes; this technique immediately demonstrates the service's effectiveness to the client. Remember that French Straightening is a thermodynamic treatment: during future washes at home, hair will not be completely straight when air-dried; however, thermal activation with a few minutes of blow-drying and brushing will be enough to reveal perfect alignment, eliminating the need for daily use of straightening irons.
Wash hair with the Pre-Treatment Shampoo, then rinse.
Wash hair again with the Pre-Treatment Shampoo, leaving it to act for 5 minutes, then rinse thoroughly with plenty of water.
Completely dry hair with the aid of a hairdryer.
Apply the French Straightening Concentrate section by section to the hair with a brush, working from roots to ends, maintaining a safe distance of one centimetre from the scalp, and distributing evenly.
Leave the product to act for 20 to 25 minutes.
Rinse thoroughly with plenty of water to remove any product residue from the hair fibre.
Blow-dry, passing the brush several times through each section.
Pass the straightening iron over thin sections, repeating the glide 10 to 15 times on each, depending on hair type. The recommended straightening iron temperature should be between 200ºC and 240ºC.
Maintenance to prolong the straight effect:
Option A (In Salon): Dampen hair, apply the Post-Treatment Mask, and blow-dry for 5 minutes.
Option B (At Home): Apply the Post-Treatment Mask during the first full hair wash. In all subsequent washes, apply the mask after shampoo, leave to act for 5 minutes (detangling hair during this exposure time), rinse with water, and finish styling with a hairdryer and brush.
Keep out of reach of children.
Avoid contact with eyes. In case of contact, rinse thoroughly with water.
Do not use on irritated, broken skin, or with scalp lesions.
In case of irritation or allergic reaction, discontinue use and consult a doctor.
For external use only. Do not ingest.
Store in a cool, dry place, away from direct sunlight.
Observe the storage conditions and expiry date indicated on the packaging.
