I think there are some shampoos out there designed for poofy hair. They might help to tame it a bit and smooth it out. Try looking a the Hairapy line of shampoos, I'm pretty sure they have one for making your hair shiny, and probably for flattening it out a bit. Just be careful that you don't use too much stuff on your hair or mess with it too much because it can end up looking greasy and worse than before. Also try looking at a flat iron. This really smooths out your hair, although you have to buy some spray to apply to your hair before you use it so you don't fry your hair.How can we make our hair flat without using any CHEMICALS OR ANY HAIR STYLES,etc?
Get a vent brush and a blowdryer. Slowly brush your hair and keep the dryer behind the brush, angled down slightly. It takes longer to dry but it's as flat as you're gonna get it.
