What is the best flat iron?
I have thick wavy hair that is impossible to straighten -_-
I have the same trouble as you, unfortunately. A different flat iron won't really help. What you need to do is straighten your hair by layers. Also make sure to use heat protectant. It may take a long time depending in your hair but it works.
None all heating products for your hair is really bad fir your hair. it damage it and will cause hair loss.
