You don't have curly hair. If you had, would be impossible to air dry after 1 month you have 1 cm of roots already of hair with different texture.

I strongly disagree with the time you take to care a curly hair × Straightned hair (I had already both). When you have curly hair, you take more time washing and waiting to get dry.

But when you get it straight you have to wash more frequently because your hair doesn't suck the oils produced by your scalp anymore. Beside that, you will have to start to blow-dry your roots after 1 month because they are growing curly. If you try to do the quimical straightening each 2 months, you will spend a loooot money, your hair will be destroyed with so many aggression and you will have to spend a lot of time in hairdresser. (It takes at least 3 hours to get the treatment done).
