Shampoo that can make your hair super-straight without making it thinner?

My hair is already thin enough! lol


My hair is mostly straight with some random waves that i would like to be able to make straight without using a flat iron daily. i started using herbal essences straight shot and it works fairly well, but the random waves still stick out a litte. PLEASE tell me if you know of an inexpensive, good brand of shampoo that I can buy at either a drugstore, sally beauty supply or target? thanks!Shampoo that can make your hair super-straight without making it thinner?
try this stuff called ';st8';. you can get it at sallys i believe...they have shampoo but they also have this stuff you put on your hair after you shampoo before you blowdry(and thats the stuff i use) its great for getting waves out.Shampoo that can make your hair super-straight without making it thinner?
if your hair is mostly straight already then i suggest just using a straightener on your hair. with a hair type like yours it should only take about 5 min.
Try Mane and Tail! It works wonders your human use!
