The ACTIVE LISSEVER BLOND KERATIN FORMALDEHYDE is a single-step treatment that comes in a 1-liter bottle. Its formula is developed to work on the hair's structure, promoting realignment and volume reduction through the action of formaldehyde, combined with nourishing and toning agents.
Key features and ingredients often include:
Formaldehyde: This is the primary active ingredient responsible for the strong straightening effect and long-lasting results. It works by altering the hair's disulfide bonds, making them straight.
Keratin: A fundamental protein that helps to rebuild and strengthen the hair fiber, restoring lost mass and improving elasticity.
Violet Pigments: Essential for counteracting unwanted yellow and brassy tones in blonde, highlighted, or gray hair, ensuring a cooler, more even color result.
Natural Oils and Conditioners (e.g., Argan Oil, Macadamia Oil, Shea Butter): These provide intense hydration, nourishment, shine, and softness, helping to protect the hair during the chemical process and prevent excessive dryness.
Other Reconstructive Agents: Likely includes a blend of amino acids and vitamins to support hair health and repair.
The product promises to deliver extreme shine, softness, and a natural straight effect, specifically adapted for lighter hair colors.
Effects on Hair
The ACTIVE LISSEVER BLOND KERATIN FORMALDEHYDE offers significant effects, particularly for lighter hair shades:
Powerful and Long-lasting Straightening: Provides an intense and durable straightening effect, effectively eliminating frizz and significantly reducing hair volume. Hair becomes exceptionally smooth and disciplined.
Tone Neutralization: The violet pigments actively neutralize unwanted yellow and brassy tones, helping to maintain a cool, desired blonde, platinum, or gray shade.
Intense Shine and Softness: Hair gains a remarkable, radiant shine and becomes exceptionally soft and silky to the touch, greatly enhancing its overall appearance.
Hair Reconstruction and Strengthening: The inclusion of keratin and other reconstructive agents helps to repair damaged areas of the hair fiber, restore lost mass, and strengthen the strands, contributing to improved resilience.
Improved Manageability: Hair becomes much easier to comb, detangle, and style, reducing daily styling effort.
Frizz Control: Provides complete control over frizz, even in humid conditions.
How to Use (Professional Application)
IMPORTANT: Due to the presence of formaldehyde, this product requires strict adherence to safety protocols and should only be applied by a trained professional in a well-ventilated area. Wear appropriate personal protective equipment (gloves, mask).
Hair Preparation:
Wash the hair with an anti-residue shampoo (clarifying shampoo) two or three times to ensure deep cleansing and to open the hair cuticles. Rinse thoroughly after each wash.
Dry the hair completely (100%) with a blow dryer.
Product Application:
Divide the hair into four to six manageable sections.
Using a brush, apply the ACTIVE LISSEVER BLOND KERATIN FORMALDEHYDE to thin sections of hair, starting about 0.5 cm to 1 cm away from the scalp. Avoid direct contact with the scalp.
Distribute the product uniformly through the strands using a fine-tooth comb.
For toning: Monitor the toning action of the violet pigments carefully during application to achieve the desired tone without over-toning.
Processing Time:
Let the product act for 40 to 60 minutes, depending on hair thickness, resistance, and the desired level of straightening and toning. For very resistant hair, a longer time may be needed.
For blonde/highlighted/gray hair: Closely observe the toning effect during this time to avoid excessive violet or gray tint.
Partial Rinse:
After the processing time, rinse the hair with water to remove 50% to 80% of the product. The exact percentage can vary based on hair type and desired result (less rinse for more straightening, more rinse for less intense straightening). Do not use shampoo at this stage.
Drying and Flat Ironing:
Dry the hair completely (100%) with a blow dryer, using a brush to help align the strands. This pre-straightening step helps in the final result.
Divide the hair into very thin sections.
Flat iron each thin section 10 to 15 times (some professionals may do more for very resistant hair), gliding the flat iron slowly and consistently from root to tip.
The flat iron temperature is crucial and must be adjusted based on hair type:
For blonde, highlighted, gray, fine, or chemically treated hair: use lower temperatures (e.g., 180°C to 200°C / 356°F to 392°F) to prevent damage, breakage, or unwanted color changes (yellowing or green tints from excessive heat).
For natural or very resistant dark hair (if the product were used on such, though it's specified for blondes): higher temperatures (up to 230°C / 446°F) could be considered, but extreme caution is paramount with blonde hair.
Consistent and thorough flat ironing is essential to seal the product into the hair and activate the full straightening and toning effect.
Finalization:
After the hair has cooled down, you can style it as desired. Some professionals might recommend a final rinse and application of a hydrating mask if the hair feels dry, then re-dry.
Important Precautions and Professional Tips:
Formaldehyde Content: Be aware that this product contains formaldehyde. Ensure proper ventilation, use personal protective equipment (gloves, masks, eye protection), and adhere to all local health and safety regulations.
Professional Use Only: This product is exclusively for professional use by trained hairdressers.
Strand Test and Patch Test: Always perform a strand test (to check compatibility, desired straightness, and toning effect) and a patch test (for skin sensitivity) before full application. This is absolutely critical, especially for blonde hair to avoid damage or unwanted color shifts.
Toning Control: Continuously monitor the hair during the processing and flat ironing stages for toning to prevent over-toning (which can result in purple or gray tints).
Avoid Scalp Contact: Do not apply the product directly to the scalp. Maintain the recommended distance from the roots.
Home Care: To prolong the effects of the treatment and maintain hair health and color, advise clients to use a quality, sulfate-free, and ideally purple (toning) home care line specifically designed for chemically treated and blonde hair.
Pregnancy/Lactation/Children: This product is not recommended for pregnant or breastfeeding women, children, or individuals with respiratory sensitivities due to the formaldehyde content.
Incompatibilities: Avoid using on hair treated with Henna/Hennê, or hair that is severely compromised, elastic, or extremely damaged. Always observe recommended waiting periods after other chemical services (e.g., coloring, bleaching).
