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

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.
