I honestly couldn't believe how well it worked to cover my gray roots. After just 2 shampoos, my roots were almost completely unnoticeable and have remained so for well over a week. Very natural looking coverage on my dark brown hair. It's so easy to use, no mixing and minimal wait time.I had to use google lens to translate the directions for usage since it was written in Korean but once I figured out how to use it, I'm sold! It's still unclear whether it goes on wet or dry hair . I tried it both ways and I feel putting it on dry hair , working it on, letting it sit while I did my other shower activities, then lather and rinse worked great for me

This for the most part in my opinion is a pretty good product but there are a few things to keep in mind. First of all the instructions that are listed on this page are a little bit off in my opinion. You should definitely follow the three to five minute instructions and not the 5 to 10 minute instructions that are listed in the pictures. Secondly, this does have hydrogen peroxide in it so the idea that you can use this all the time is probably very wrong for most people. It will almost certainly damage your hair if you use it constantly. This is definitely something that you would use once and then shampoo with a few other different shampoos for a while and then go back to using this once and then return to other shampoos, repeating the process. Which means that coloring your hair with this is a slow endeavor but in my experience with it, it does work if you have the time and patience. The third thing to keep in mind is that this stains. So you need to make sure to be wearing some clothes that you're not particularly concerned about and I wear gloves when I wash my hair with it to make sure that I don't stain my hands. Also wherever you're washing your hair make sure that you have a sponge with soap nearby so that you can wipe away some of the stains that are going to happen on your shower or in your sink. The fourth thing is that when I first tried this, I only used this for the least amount of suggested time so for 3 minutes and I didn't use it on my scalp because I wanted to make sure that it was safe for my hair and I would suggest that to others because frankly, it's going to take quite a few uses to really get rid of all the grays so you might as well test it out just to be careful by not putting it on your scalp the first try. A positive I would say about this is that it really does target the gray hair and leaves the rest of your hair alone, so it does in my opinion look very natural. I think the value is very reasonable for what you get if you are comfortable with the fact that this is a process and is not something that's going to make your hair look perfect after one wash. I would definitely make sure to get yourself a good leave-in conditioner and probably a hair mask to make sure that you're hydrating your hair enough after using this. Last thing, keep in mind that this is a Korean product that doesn't have a bottle made for an English speaking audience so, the only thing that's in English on this is the ingredients.

3.0 out of 5 stars Will Take A While To Work

My wife has been trying this shampoo to cover a medium amount of gray hair. The shampoo is dispensed as two streams side by side, with one being white and creamy and the other dark brown. The brown component will stain if it drips onto the floor or clothing, so be careful. The directions state to treat hair with the product for some minutes and then shampoo and condition as usual. So far, she has not noticed much result. Her hair does seem to be drier after using the shampoo, even after conditioning. One problem with the shampoo is that it probably needs to be used every day to appreciate the effects described. Since my wife shampoos less often to maintain her hair health, the effect will probably take a long time to notice.

It's a nice bottle; you need to tilt it when dispensing (not straight up). The bottle and the container do not have any instructions in English, but you can refer to the Bolo page for instructions on how to use them. The bottle already has a mixture, so there is no need to mix liquids 1 and 2 (as the Bolo page says). The smell is unique; it's a little bit like sulfur or something, not too pleasant, but it's ok if it works. And it does work! After only one use, I can see the difference. My gray is reduced by 20-30%. And the hair is soft and smooth. I will continue using this to see how it will improve my hair.
