well if you have a blow drier that will make your Hair pretty damn straight but if you don't i have noticed that if you comb your hair wet and then put it in a pony tail putting a Hair tie every so inches down the pony tail and then go to bed your hair will be pretty straight when you wake up but it matters how curly your hairIs there a way to achieve the look of pin-straight hair without the salon or a straightener?
It really depends how curly your hair is. If you don't have any hair supplies (straightener, blow drier ect) there's not much that you can do~
a blow dryer woks good, but since a blow dryer would make your hair frizzy, i suggest after you blow dry it, but some ';frizz ease';'; on it
try blow drying it..?
