How often can I use hair steamer for my hair?

I have recently bought a hair steamer home, and I am confused how often can I use it for my hair. Actually, I use hair steamer every alternate day 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 hair steamer on hair in the evening as well. Can some hair expert please advice if it is prudent to use hair steamer on hair two times occasionally? Would it not make my hair thinner? Please advice. I would be thankful to you!
