I am 23 year old male with wavy (not curly) dark blonde hair that I keep at medium length, short but not too short. I would like to grow it out more because it is so wavy and thick that it always gets bushy and kind of fro-ish. I want to know from the people who are expert in this field about how to get my hair straighten. Is there any safe and easy way to make my hair straight so that I can have longer hair without any problem? I would really appreciate your useful information at the earliest. Thanks.
