OK by what you are discribing, the procedure was done improperly. Sounds like you were overprocessed. Also, the reason why your hair still smells like the relaxer is because it was rinsed out incorrectly. When rinsing out relaxer, the water must be at the correct temperature. If the water is to warm it will diminish the effect of the relaxer. And if it is too cold for the procedure, it will cause the scales on the hair cuticle to close up. Holding the hair relaxer molecules trapped inside the hair. This will cause your hair to smell(or rather stink) for weeks after the procedure is done.
Whoever relaxed your hair did not do it right. Unfortunately the only way to get rid of the relaxer is to grow it out. But there are things you can do to make it better while that happens. Get yourself a bottle of Nexuss emergence. Treat your hair with every two weeks for the first month and a half. After that, use it once a month. That will stop breakage and fall out and improve the condition of the hair. remember to deep condition after the treatment. Protein treatments are designed to buffer damage not to soften hair. If you don't deep condition your hair will feel dry and nasty. Other protein treatments you can try are Joico reconstructor and Redken deep fuel. They all work great, and have the right molecular weigth to actually work.
If you ever want to relax your hair again (belive me, eventually you'll want to try it again) Try Thio based relaxer instead of Sodium hydroxide. They are designed to texturize hair instead of relaxing it. That means hair will be smooth and frizz free when blow dried or flat ironed, but you will still be able to wear it curly. Your curls or waves, will just be looser, smoother, shinier (get the picture). Rusk Radical anti-curl, X-tenso by loreal, or redken vertical are all exellent. I also heard someone say framesi makes a really good one, but I have never tried it.
Anyway, do the protein treatments and deep conditioning. It will take about a month before you see the results, but you will thank me.
Good luck.
Shary.
