afro hair types aren't ideal for the j-perm but its do-able. the thing is, when you get new growth the hair will be super fragile at the point where the curly new growth meets the j-permed straight part. at the point it can break off really easily.
if you have really long think hair then the weight of the hair can help keep the new growth less curly and less prone to breaking off where it meets the straightened hair.
if you already hair straight or wavy hair you can get the j-perm no problem. slightly straight to wavy hair types are the best candidates for it anyway.
i posted the following before but not everyone takes the time to read through previous posts. you should really take the advice to heart, especially if you have coarse curly afro hair.
this is what i posted previously:
so i posted awhile ago a couple of links about the j-perm. i was gonna get the bio-ionic brand of the j-perm done, but after talking to a very extremely knowledgeable stylist, i decided against it. i am african-american and regularly use a relaxer to straighten my hair. I was told by this stylist that i shouldn't get the j-perm b/c 1. its not great for african hair types 2. you can't put it over already processed hair (but color-treeated hair is ok).
whatever questions you have you HAVE to go to this website :
http://www.verticalsinhair.com/intro.shtmlthere is so much detailed info that is extremely helpful on that site. the stylist Steve is the one who warned me about getting the j-perm with my type of hair. there is a forum on the site and you can register to go on there and ask him questions. he always answers and fairly quickly...within 24hrs.
so, go to that site and take the time to go to every page and really get good info about the j-perm and also go to the forums and ask Steve questions...he saved my hair from possibly falling out! its good info for anyone but if you are african american and want the j-perm, ask for Steve's opinion before doing it!! some african hair types are ok, esp if you are mixed, but there are other concerns that he can inform you about...many stylists esp in the US don't know everything he knows about straightening hair...he's an expert.
oh yeah, he's based in toronto. i hope everyone checks out his site, its great! and you'll find it super helpful!
