my sister got it for christmas and i got a really nice curling iron and i starightened my hair with it and the next day tried to curl it with my curling iron and it wouldnt curl, so if a really good curling iron cant curl it the day after, doubt humidity can. and it made my hair really shiny and healthy looking and my sisters too.What hair product keeps ur hair straight and healthy looking all day?
I have tried everything and no shampoos or cond or products work on my hair...I use a flat iron and that works great and I don't have to even put in hairspray. keep a low setting so as not to burn your hair. I put in a heat protector before using. no products that I used have ever kept my hair straight. I do use Redken shampoo and cond and it works better then any others.



You said you don't want to spend a lot of money so you can go to Walmart and get a hair flat iron for 35 dollars I got the wet2straight for like 35 doll and my hair stays straight in the rain or highest wind. And I have really frizzy hair. Good luck hope this helped
you should use protein hair shampoo and conditioner! i use it, it's really good!
i use this Paul Mitchell styling spray gel and my hair stays straight all day
