Instant Dark Brown Hair Dye Shampoo for Men & Women, 3-In-1 Color Treated Hair, Lasts 30 Days

Introducing COSMTEK Hair Dye Shampoo, with a new formula and upgraded process. Our unique conditioning compound contains active ingredients that protect hair fibers from the inside out. Just 5-10 minutes is all it takes for grey hair to transform into its natural black shade. This 3-in-1 hair color shampoo not only dyes hair but also cleanses the scalp and nourishes the hair while coloring it. Plus, one bottle is equivalent to 3 bottles of regular shampoo.

COSMTEK, a brand with its own independent research and development team, has been dedicated to creating hair coloring shampoos for many years. With a professional knowledge base and excellent process technology, our products are trustworthy.

In addition to the hair dye shampoo, we also offer MEIDU Dark Brown Hair Shampoo, MEIDU Black Hair Shampoo, Hair Removal Spray Foam for Men, Scalp Exfoliator Scrub, Detangling Brush, and Hair Removal Cream for Intimate use.

Our color depositing shampoo has been optimized with a formula free of preservatives, sulfates, and ammonia, providing peace of mind for our customers. We've also added Argan Oil, Olive Oil, and Turmeric to our semi-permanent hair color, leaving hair smoother and frizz-free.

Whether your hair is white, gray, or light brown, our lacquered black hair dye can transform it into a beautiful dark brown shade in just 15 minutes. Easy to use, simply apply the color shampoo to wet hair, leave it on for 15-20 minutes, and rinse thoroughly for a natural, effortless dark brown look.

This shampoo maintains its effectiveness for 4-5 weeks after each use, and for prolonged color vibrancy, we recommend using it once every 15 days. Our products have received positive customer reviews and are competitively priced, making them a great choice for anyone seeking high-quality hair care solutions.
