No English version, but the instruction might goes like this:

I pour cleanser in a glass, wait for about 2/3 minutes, wash it off by stirring it gently, and rinse it off with clear water, . :) Not bad, its residues fell out in 2/3 minutes, and the brittle are fine :)) Done!

It's not really a magic, but not a bad product also. For me, it's a matter of needs. The best thing in doing this cleansing is, one step concise many steps than shampooing your brush.. hehe!! :))
