Flat irons are definitely the best for getting your hair straightened but it does damage your hair quite a bit. Brushing and blow drying will also damage your hair but not quite as bad I don't think. For the best results, go with the straightening irons, heat protection shampoo and heat protection spray to put on after washing.Which was is better to straighten hair - Flat Iron of Blow Drier?
Well... straighteners damage your hair way more, even with heat protection spray. Hair driers damage it less, but they can leave your hair looking frizzy and a bit dry. So its up to you really. I am trying to grow my hair too, and all i do is let it dry naturally and the put it up in a ponytail or bun. =)
If you want your hair straight, the flat iron is better. Just make sure to use heat protection to avoid alot of damage.
