I should start off by saying I'm not black, but my hair is frizz-prone and lately has been very tangled and overall looking crappy. In any case I slathered this all over my hair and kept it on overnight. My hair is really long so I was surprised at how little I had to use in order to completely saturate my hair. Anyway I am so excited about how soft and smooth my hair is now, like it used to feel after I got Brazilian Keratin done. The smell is also great. I figure I'll have to keep using it overnight every couple days to keep the results, but at $3 for a jar that's probably going to last me a long time, I have no complaints.
