yes it is a liquid relaxer, I actually gave my daughter one when she was younger to help w/that thickness. It actually removes access bulk from the hair and presses will last. It is veeeeeeeeeeeeery driing so you will need to follow up w/a hot oil treatment and constantly feed your hair moisture to bring it back from the desert and yes it does stink but you can follow up w/another poo afterwards for frangrance. When you do apply it you have to start combing it w/a wide tooth comb working your way down to a smaller one for the time stated. The combing is what actually helps relax the hair, my cousin also received this for years appose to a relaxer and I say w/ all the driing it does you would be better off just relaxing your hair or texturizing if you think you may not be able to over come the dryness. But if you do decide to go w/this you can wear your hair as if it was relaxed in any style you choose, just blow driing gets the hair really straight and appling jam doesn't make the hair revert so quickly.

As for what can help your presses last soemtimes depending on the hair you may need just a light serum as oppose to something heavy, you may have to try out a few things first, but it you thing your hair needs something light I'd say go w/Wonder 8 oil, Medium go w/WGO or Silk Touch pressing cream by Liz and Daughter (smell like candy too), Heavy go w/Curling Wax by Ampro. You will also have to incorporate this w/a hard press which means you will press the top and bottom of each section maybe 2x's and you would want to use a good pressing comb that has been tempered.
