How can I fix my hair that won't stay flat?

What do you do with your hair if it wont stay flat. My hair has tones of knots and when I brush my hair it tangels it in an hour at the most! My mom wont let me get a straghitening iron.I need help! please, HELP I NEED IT!!!

Hey I too had a problem getting my hair to lay down, and the humidity makes it even more of a bear!!
I have found that Garnier Fructis Smoothing Milk is one of the best products I have tried.
I put a little bit in my hand and then massage it into my hair and comb or brush my hair and let it dry. the hair lays down and stays put.
Even my husband has started using this product and he really likes it!

try washing your hair at night that usually keeps it flatter.
While I was a t camp I borrowed some of my cousins hair products, "zero Frizz" wow! I didnt think I had frizzy hair until I put that in my hair it made it sooo mush softer and taimed, it was shiny and soft. you HAVE GOT to try it, it works!
just put a little bit (tiny bit or it will make your hair appear oily)in your hand and rub them thru your hair.
tell me if this helps

I have been completely spoiled by a product called Biosilk. You can only get it in salons. When you hair is damp, use a tiny bit and work through your hair with you fingers, then comb. Do not brush wet or damp hair. Start at the end of you hair and work your way up to the roots when combing out tangles. Whether you allow your hair to air-or use a blow dryer, when your hair is dry, work an even smaller amount of Biosilk through you hair and then comb smooth. A small amount is the size of pea. It does not take much. It will leave your hair frizz-free and shiny. You will just love to run your fingers through your hair after using Biosilk. One more thing you can do is before you get in the shower to wash your hair, brush out all the tangles. Start with a tangle-free head and you will have better results that last through out the day. I am not able to wash my hair the night before because it looks oily in the morning. I am sure some of the other products are great, but Biosilk is the best and one small bottle will last you a very long time. You can even use Biosilk on your skin.

Yes, I have used Biosilk in previous years when I would get a perm. It is a very good product and true, you can find it in your quality salons.
