As a licensed cosmotologist there is no shampoo to make your hair straight
You have to use hair products to get your hair straight by you still need to add heat to pull the curl out you can use a hair dryer instead of flat iron. You can also try using a leave in conditioner to add a little weight to the hair to pull the waves out a bit. But it is safe to use a flat iron or hair dryer on your hair every day as long as you use a heat protecton hair product on hair first. Paul Mitchell makes a mans line so does redkin I like Chi silk infusion for the flat iron I think it does have a more manly smell because its not fruity or flowery smell. Either way you can't get your hair straight unless you put some work to it until your hair grows out more because the longer hair gets the less wave/curl there is since there's more weight. Hair structure can only be broken temporary by heat and water and only a permanent change is by chemical. Which for you I think would be pointless to go the chemical route since you only have wavy hair. My personal opinion with out knowing what your hair texture is. I would blow dry your hair straight down the take a palmate like kenra texturizing taffy or redken rewind. And rub that through it will piece out some strands but also put weight on your hair to pull the waves out.the only problem with putting products in your hair is if you have fine hair texture then you have to wash your hair every day and that not healthy for hair and scalp since it washes away the natural oils.you may have to try several products out before you find what works for you if you buy the products from a salon you can return it if you don't like it. I would recommended to go to either beauty bar Regis master cuts or the salon in wal. Mart or Jc pennys salon to get the products on they can help you find what will work best for you and two they always have sales specially Jc pennys. And all those Stores do refunds or exchange.
