I have really thick black kind of hair, and its nothing less than an ordeal to straighten up the curls of my hair. Until now, I had a local flat iron, which took me no less than 25 minutes to straighten my hair. Therefore, I have finally thought of asking for the best brand for a flat iron. I read a lot of good things about Chi, however, there was a percentage of people favoring Sedu. I didnât quite notice any significant difference in the price of flat irons of both the brands. Therefore, I would like to know from somebody who has used both the brands, that which of them do you think would be less time consuming and more efficient simultaneously. I would love to hear from you guys at the earliest possible! Thanks.
