Permanent Hair Dye Shampoo for Men & Women

The COSMTEK brand takes pride in its independently developed hair dye shampoo, backed by a professional research and development team dedicated to the field of hair coloring for many years. With a strong knowledge base and excellent process technology, the brand has produced trustworthy products.

To validate the quality of their offerings, the COSMTEK team conducted a user trial with 124 randomly selected participants. The results were impressive, with a 96% satisfaction rate and 98.4% of users expressing a willingness to recommend the COSMTEK shampoo to others. These real-world data points underscore the brand's commitment to delivering reliable and effective products.

In addition to the COSMTEK shampoo, the product lineup includes several other options catering to different hair color needs. The MEIDU Black Hair Shampoo, DEXE Black Hair Shampoo, and MEIDU Dark Brown Hair Shampoo provide comprehensive solutions for those seeking to enhance or maintain their hair color. Furthermore, the Scalp Exfoliator Scrub and Detangling Brush from Bablabear offer complementary products to support a holistic hair care routine.

Addressing the concerns of modern consumers, the COSMTEK shampoo has undergone a formula upgrade, now being free of preservatives, sulfates, and ammonia. This formulation change provides users with the peace of mind of using a product with a transparent and conscientious ingredient list.

To further enhance the performance of the color-depositing shampoo, the brand has incorporated nourishing ingredients such as Argan Oil, Olive Oil, and Turmeric. These additions have been effective in helping to smooth hair and reduce frizz, ensuring a better overall experience after using the shampoo.

The versatility of the COSMTEK shampoo is another noteworthy feature. Whether your hair is white, gray, or light brown, this product can effectively transform it into a deep, lustrous black. Furthermore, the natural hair dye can also be used to darken beards, providing a comprehensive solution for those seeking a dramatic color change.

The application process is straightforward, requiring users to simply apply the shampoo to wet hair, leave it on for 5-10 minutes, and then rinse it out completely. This effortless approach ensures a hassle-free coloring experience.

The long-lasting results of the COSMTEK shampoo are also impressive, with the color being maintainable for 4-5 weeks with a single use. For those who wish to keep their hair in a shiny, black hue for an extended period, the brand recommends using the product once every 15 days.

Overall, the COSMTEK hair dye shampoo and the broader product lineup from the brand demonstrate a commitment to quality, innovation, and customer satisfaction. With real-world data to support its effectiveness and a focus on safe, nourishing ingredients, the COSMTEK brand offers a compelling solution for those seeking to transform their hair color with confidence.
