use in a ventilated space! [SEP] first the elephant in the room - read the ingredients and you will see there is formaldehyde.  technically this is terrible but it is somewhat manageable.  be in a ventilated space.  personally i turn the bathroom fan on while i am using it for the whole process - especially during the flat iron part.  i also turn on a regular floor fan pointed into the bathroom, whatever i can do to keep the air moving.<br /><br />ok - now that we have covered that - the actual product.  it's sooooo easy to use.  the process is so simple and easy.  the directions are super easy to understand and follow and there are pictures included.  it's pretty quick - you can get through it all within an hour once you get started on the actual product.  just follow the directions.<br /><br />then for maintenance between treatments there is a shampoo and conditioner provided.  these are EXTREMELY thick!  like the conditioner is so crazy thick it's almost too difficult to get it out of the bottle.  it's a workout.  but it's all good to help maintain though.<br /><br />now - the results.  i'm not disappointed at all.  i know it's working.  it's not a crazy perma-straight situation though.  this is NOT salon results.  let me repeat that ... NOT salon results.  i have super natural curly hair - i can still wash my hair curly.  the same amount of curls as i have always had.  when i do wear it curly though, i also still have the same amount of frizz.  it's sad and true.  that said though - it's when wear it straight that the product shows it's worth!  the picture i have posted it right after coming after getting caught in the rain.  in the past my hair would just revert back to the full on curl, no waves just the game of 'how big is my hair gonna grow?' watch party.  this time though ... i ended up with a style that i actually like!  something i could easily still get away with wearing for the rest of the day/evening.  as rainy and muggy as it has been lately - i can dig this and appreciate it through and through.<br /><br />so all that said - do i wish it did a bit more for the curly hair frizz ... yes.  but for the price and the fact that i will probably get 4 treatments out of this set - i think the system is worth for the investment - cost and time.
