[Korean dye shampoo] CHEONGDAM STYLE FOREST BLACK CHANGE SHAMPOO, Semi Permanent Hair Color Darkening Grey Hair Dye Coverage Volume, Peptide Ceramide Hyaluronic Acid Paraben Free 6.7oz (Black)

I have to dye my hair every 2 weeks to cover up my roots. This shampoo works great to temporarily color my new growth in between my monthly color appointments! For best results, I pump out the shampoo into a small bowl and mix it up. Then with a small brush I apply to my roots for about 30 min (similar process to coloring my hair). Smell is not as strong as traditional hair dye.

I gave this product a 3 star review because all the instructions and ingredients on the bottle are written in Korean, and there are no English version! I used few times, and it does the job, but you have to be careful how long you leave it on your hair, since there no instructions that you can understand, because the color change is very fast.

This is not a shampoo, it is no more than an oxidative hair coloring product in a dual pump that looks like a shampoo bottle. You know how a typical hair dye comes in two parts. One coloring liquid and an activator, or, in this case hydrogen peroxide. You pump the two liquids and mix to make a coloring mixture, and color your hair, then use your shampoo to wash and rinse. How is this different than just coloring ?

I have used it for almost a week, the heavy white hair turn to gray and the light white changed to black. Every day I used it I notice a change for better and all people around me have noticed the change. The only down side is, no much details on the directions of use and no review videos in you tube. Generally I like it and recommend it for thous having little white or gray hair and need something easy to use.

I strongly recommend it! It works for me. When I first used it, I doubted that the color would change, but when I trusted the product and continued to use it, I was able to see it turning remarkably brown from the fourth day. Follow the instructions on the label. You don't have to stay longer than instructed. It works gradually, not immediately. It is recommended that you leave on for 5 minutes while you do other things and then rinse. Super easy!

It was the first time using hair coloring shampoo. I have grayish black hair and I'd wanted to hide the gray hair. After using 4-5 times, my hair color became very dark brownish black. The hair color gradually changes after each time washing my hair using this shampoo. Now it almost all covered the white part of my hair. If you like very dark color hair, this is the product. I recommend this shampoo and will definitely buy it again.

Since I am allergic to hair dyes, I have been using ppd free, ammonia free products. Although this product states that it is paraben free, it is unclear about other allergenic ingredients. Again, do not use this if you are severely allergic to hair dyes.

This product delivers what it claims. My hair (after 15 minutes, that’s the time I usually do with color pigment hair mask) got a very black tone. It almost shows nothing covering my newly grown white hair but makes my chestnut-dye hair much darker.This shampoo has two agents. The black agent has ammonium chloride. The white agent has alcohol and hydrogen peroxide. I don’t feel any irritation from using it. And in fact, my hair feels soft. However, I don’t like the hydrogen peroxide in this so I will return it.
