Is Kao Japan foam hair dye good? Will it fade easily?

Because it is foam, the hair can be dyed evenly, both inside and outside.

Kao is a Japanese brand. I don't know where you bought it. I suggest you check the records on the package carefully.

I have used Kao foam twice, and the color fading is not obvious. However, the secondary dyeing effect of new hair after the hair roots grow out is not very good. Will form a color difference. That is, the root is 2 cm because the newly dyed color is darker, and the hair below is lighter because of the second dyeing.

Personally, I prefer reddish colors.
