Whats a good hair product to use when straightening hair?

My hair is naturally super curly, so when I straighten it, its doesn't stay straight for long and goes into these annoying wave things. What products can I use to make my hair stay straight? I don't have the best flatiron, just an old conair, so getting a new one's not an option right noww. help?? ten pts.Whats a good hair product to use when straightening hair?
My hair is super curly also, I use Organic Olive Oil (you can try Organic Root Stimulator) and Organic Olive Oil Spray. What I typically do is wash my hair and do a hot oil treatment, I immediately blow dry my hair straight and then apply the Olive Oil. I then re-straighten my hair with a flat iron, and then spray my hair with the oil spray. The spray is light and has an all natural scent, I have long hair and it is super curly and thick (I am Black and Puerto Rican) so I typically wrap it and then do a quick hot iron tough up. After that my hair will last for about a week with minimal humidity/moisture contact.





I use the Revlon Perfect Heat Ceramic Straightener (19.99 department store)





Even with all this rain and sweet are still my hair's worst enemy. LOL





Good Luck I hope you find the balance for your hair.
