I am confused how often can I iron my hair. Actually, I do iron hair every morning before leaving for work, and my hair is already fine, however, since my friend has arranged a party this weekend, I want to confirm whether it would be all right using iron on hair in the evening as well. Can some hair expert please advice if it is prudent to iron hair once in a while? Would it not make my hair thinner? Please advice. I would be thankful to you!
