How to fix poofy hair?

My hair is always so poofy I really don't have a problem with frizzy it's just poofy I want it to lay flat and not be poofy how do I do that.

my hair is pretty thick could that make it poofy ?

well stright it thats what I do everyday

use a chi straightner

change shampoo and use loads of conditioner. blow dry it then get your irons out, use the mainly on the top parts. you can also add some product to help control it and keep it all in place =)

Anti- frizz, and a straightner, or for best results contact your hair stylist. :]

Use a good moisturizing shampoo and conditioner, flat iron it, and use some sort of pomade or syling wax to help weigh it down.

straighten it lol I do but then again I make my hair puffy on purpose

I think I know!
See, I have this problem too. Except my hair is curly, very frizzy and my hairdresser says I have enough hair for 6 or 7 people.
Uh-huh.
And as well, my hair poofs out to at least 6 inches away from my face.
So far, I've been trying mousses and gels and anti-frizz cremes and they seem to be working for me.
If your hair is curly or wavy like me then try Dove Curl and Sculpt mousse and I'm using Tresemme flawless curls gel or Panten curl defining gel.
If it's straight, then yeah, you should straighten it.
Hope I helped!
