The Thermal Seal Plastica dos Fios Kit is an intensive treatment that reduces volume, eliminates frizz and provides smooth, controlled strands for up to 3 months. It deeply nourishes and hydrates the hair, as well as giving incredible shine and strengthening the structure, preventing breakage.

Contains: Plastica dos Fios Step 1 Pre-Sealing Shampoo 1000ml: Deeply cleans the hair and helps to open the cuticle, facilitating the penetration of the active ingredients of the treatment.

Plastica dos Fios Thermal Sealing Step 2 - 1000ml/33.81fl.oz: With other products, it promotes a long-lasting natural straight effect on the strands and leaves hair shiny and frizz-free.

Plastic Hair Sealing Mask Step 3 1000ml: Promotes maximum hydration of the hair, reducing frizz and accentuating the straightening effect.

Action: Treatment composed of Arginine, Açaí Extract and Acetic Acid (acidic pH).

Açaí Extract: rich in nutrients such as Vitamins, Essential Sugars and Emollient Oils. Its antioxidant and protective action promotes complete regeneration of hair, hydrating it efficiently and for a long time.

Amino acids: balance the structure of hair from aggression caused by excessive use of dryers and straighteners. Increases its manageability and elasticity, leaving hair smoother and extremely easy to comb.

Phytonutrients: Nourishes and protects hair, helping to regenerate damaged and worn parts.

Acetic Acid Shampoo: as it has an acidic pH, it can cause irritation and peeling on sensitized leather. For this reason, we recommend not using it on pregnant women, people with sensitive scalps and children up to 12 years of age.

Note: Provides approximately 35 applications. Micro Quality Labs (USA) and Anvisa certified. The effect is prolonged with the use of Plástica dos Fios maintenance products.

It should not be applied to pregnant women, people with sensitive scalps and children.

Application: Requirements: silicone gloves, dryer, straightener, plastic flaps, comb, brush and plastic container.
1. Wash your hair with Step 1, massaging until foam forms. Wash twice for very resistant or very dirty hair. Leave to act for 5 minutes and rinse thoroughly. Warning: Do not rub your scalp
2 Dry your hair 80% with the help of a hairdryer and your fingers.
3- Separate the hair into 6 parts (a vertical line separating the hair into two sections - right and left - and three horizontal sections - neck, middle and front of the ears).
4- Pour 20 to 40 ml from Step 2 into a container and put on silicone gloves.
5. Start by applying it to a section of hair on your neck with the brush. Apply two fingers away from the roots at the base of the strand and pull the product to the ends with the comb. Make sure the product is on every strand of hair.
6. Repeat with the side strand.
7- With the dryer on a cold setting, dry two strands of hair to 100%. It is important to dry two strands of hair at a time with a cold spray. This prevents the formation of smoke and prevents the product from evaporating without effect.
8. Repeat procedure 5 to 7 on the two central strands of hair, one at a time.
9. Lastly, repeat procedure 5 to 7 on the two front strands, drying the strands towards the back. It is important that neither the wind nor the hair with the product comes into contact with the face.
10- Time to use the straightener! For blonde, damaged or chemically treated hair, the temperature should not exceed 200°C. For normal, natural or resistant hair, the temperature should be 230°C.
11. Divide your hair into sections again. Separate a thin section of hair and iron it 10 times (temperature 200°C) or 7 times (temperature 230°C).
12- Iron the ends of your hair (not the length) 4 times (temperature 200°C) or 2 times (temperature 230°C). This way you avoid the artificial straight effect on the ends of your hair.
13. Repeat this process (steps 11 and 12) on all hair. The straight blow against the leather makes the hair straighter naturally from the roots.
14- After using the straightener on all the hair, rinse well with water.
15. Apply Step 3 to the hair, gently massaging the hair. Let it act for 5 minutes and rinse again.
16. Dry your hair with a hairdryer.
