To clarify, we transfer the contents from the liter into a 4.7-ounce refilled bottle, filling it all the way to the top. The items are genuine. I personally order keratin from the distributor every few weeks, and each batch is slightly different. I’ve even noticed variations in consistency between batches. However, since I own multiple salons, I distribute the merchandise among each salon manager. This way, the operators and stylists can allocate the products as needed.


Occasionally, I may receive a batch that appears darker, thinner, or thicker. These variations could be due to the items being stored in the warehouse for a few years or even months. Importantly, there are no expiration dates on the batch bottles themselves, so I’ve never questioned their quality.


I ensure that all products are dispatched the same day they are shipped. We label the bottles ourselves to avoid confusion with other salon products like the Brazilian blowout or the Coppola keratin complex. Each stylist prefers a specific brand, and I respect their choice. I carry all their products, as well as those preferred by clients. The products have always worked for me because they are filled from the original 32-ounce size. So, place your order with confidence knowing you’re getting it directly from the source. If you need any help or have any concerns about application, don’t hesitate to reach out. I’m happy to guide you through it. Not only do I own the salons, but I’m also an operator with 30 years of experience in hair texturizing
