The “Keratin Queen Brazilian Treatment 3/Set 1L 33.81 Fl OZ” appears to be a professional keratin hair treatment system commonly used for smoothing and straightening hair. Here’s what the set likely includes: 1. Step 1: Clarifying Shampoo Designed to deeply cleanse the hair and remove impurities, opening the cuticle for the keratin treatment. 2. Step 2: Keratin Treatment The primary product that helps smooth and straighten hair by infusing keratin into the strands. Reduces frizz, enhances shine, and promotes manageability. 3. Step 3: Sulfate-Free Shampoo/Conditioner Used to maintain the results of the treatment. Gentle formulation to avoid stripping the keratin from the hair. If you are considering using it, make sure to follow the instructions carefully, as keratin treatments often involve heat (like flat irons) to seal the product into the hair. Additionally, ensure the product complies with local health and safety standards, as some keratin treatments may contain formaldehyde or similar chemicals.
