Does anyone know about these hair systems?

I'm asking about the Japanese Straightening system, and the Hair Integration wigs that have come out recently. Does anyone know anything about them, or use them?

I wanted to know if the Japanese Straightening system worked well on African American hair, and if so, about how long does it last before a touch up is needed?

Regarding the Integration systems, does anyone know how long you're allowed to keep those in? Do you have to take them off nightly? or can they stay on for months at a time? If made of complete virgin hair, can you dye it? (I want to use Sally's Color Jamz Semipermanent hair color).

Thank you in advance for your help. If I have additional questions, I'll post them up.

I don't know about the integration system but the jap straitening will work on your hair HOWEVER and this is important ... if you have had a relaxer you cannot do it. The chemicals from the first will not react well the the Japanese straitening and it will burn your hair off... not good not good at all.. Also if you have any bleach in your hair it is a no no it will last forever on the hair that is treated but you will need to get the regrowth done maybe ever 4 months? it depends.
