Reviews about BBcos Keratin Deco

I do not recommend this product. When mixed, the scent of the product is similar to shampoo, but when it reacts with the hair, it starts to smell awful. I lightened my natural roots, but the result was patchy and turned out to be a bright gold/red color with reddish-golden patches. My natural hair is not dark, it is light brown with an ashy tone, approximately 7-8 shades. This is the first time I have achieved such a color using a bleaching powder. 10 minutes after applying it, my skin started to itch terribly, and after 15 minutes, it was like hell on my head. It felt like needles were poking my scalp, and my skin became inflamed and red, resembling a chemical burn. It is possible that I have an individual reaction to this product, although I have never had such problems before. Several hours after the procedure, I started experiencing terrible itching and dandruff.

I have a blond color, slightly with a yellowish tint, and the powder perfectly removed the yellowish tone. I did everything myself. I liked it.

The product brightens quite well and doesn't create dust. I tried it with a 3% and 6% developer. I left it on for 40 minutes and achieved a level 4 result with a 6-level oxidizer. The delivery was prompt, and the store's service was of high quality. Thank you!

This product works great for lightening and has no unpleasant odor. I have been using it for about a year. I would recommend expanding the range of products, especially in terms of colors and developers.
