here r sum shampoos u can try....-
1) sunsilk straightning shampoo
2) satinique shampoo and mosque
3) avon straighntning shampo
choose a good shampoo that wont dry out ur hair so choose 1 tht suits ur hair type. sunsilk is good becoz it works on any hair type. satinique is my best reccomended becoz it duz wonders for ur hair!! criusly, once u use it hair is so soft n silky n straight!!!! its just relli astonishing....and its from a very trusted company-amway. try it n i 100% guarentee u will be satisfied. avon straightening shampoo has satisfying but not excellent results. dove damage repair is good bcoz is givs therapy 2 ur hair making it much more managable n easy 2 straighten. so after using 1 of these shapoos,
lather generously, and rinse. then use conditioner, and rinse, but dont wash it out completely. 2% of it shud still bve left in ur hair. wen u apply conditioner, take ur comb and comb ur hair straight down. wait wid conditioner on ur head for 10 minutes. then rinse, leaving 2%. wen drying hair, blot, dont rub. den comb straight ur wet hair. comb straight and hold comb at end of hair, wid comb still in hair, n wid a hair dryer, dry that portion of hair. do this to all ur hair and it will be straight. alte5rnativly, if u dont hav a hair dryer, apply hair straightening gel over damp hair. comb 2 minutes after applying. wen ur hair dries, it will be straight!!! good luck, hpe i helped!!
my mom is a certified cosmetologist, and i had the same problem as u did.
