Main highlights
- THE BENEFITS OF KERATIN STRAIGHTENING SYSTEM ARE PRICELESS. The protein molecule penetrates deep into the hair’s structure, renewing it from within. The result is hair that is flawlessly smooth with a natural luster. Our formula deeply revives and restores hair to create long-term, maximum protection on the hair’s surface. Due to its composition and properties, keratin is suitable for use on fine, thin, wavy, frizzy hair. The more frizzy the hair is, the more effective the product will be.
- KERATIN STRAIGHTENING HARNESSES THE POWER OF KERATIN TO OFFER FIRST-CLASS HAIR REGENERATION. Our hair straightening formula is designed to bring back your hair’s natural shine, strength, and beauty. By restoring depleted keratin levels, it revitalizes your hair’s appearance and transforms dry, damaged curls into the luxurious, glossy hair you’ve been dreaming of. We use NO formaldehyde and promise NO harmful fumes. Keratin treatment leaves hair smooth after the first treatment.
- HOW DOES IT WORK? As a natural building block of healthy hair, keratin has the power to immediately restore damage and help you achieve a sleek, salon-fresh style. Over time, keratin deficiency leads to brittleness and leaves your hair open to ongoing damage and breakage. Restoring keratin levels and allowing keratin to be re-sealed into the hair’s structure supports your hair’s protective coating and health. It also moisturizes hair and imbues it with additional strength.
- FROM BRAZIL WITH LOVE! OUR UNIQUE FORMULA INCLUDES WHEAT, SOY, CORN, RICE PROTEINS, AÇAI BERRIES, AND VITAMINS B5 AND B3. Our ingredients are specially chosen to enhance the action of keratin and provide additional hydration, revitalization, and regeneration. It’s here, in Brazil, that this popular salon treatment was developed. Now, the benefits of keratin straightening have become famous around the world. It’s time to say no to pesky split ends and brittle fly aways!
- AMAZONLISS INSTANT-ACTION FORMULA HELPS TO RESTORE HAIR IMMEDIATELY AND RESULTS ARE NOTICEABLE AFTER THE FIRST USE. Brazilian hair straightening relies on the power of this protein to achieve total hair transformations. You can also use keratin treatment after coloring or bleaching your hair. It is recommended that you repeat treatment every 3-4 months; this is because Keratin accumulates in the hair structure with each treatment. Regular treatment ensures your results are long-lasting.
