Sorry there is not pill to make your hair straighter. It's in your DNA.
What you CAN do it buy a Paul Brown straightener [the one I have]. I have a friend whom has very very curly hair and it's all a mess and when I straighten it with my straightener it's like sleek silky magic. [you can find it on
www.ebay.com]
I'd also suggest going to your local hair salon and getting some straightening balm to protect your hair from damaging it-- I wouldn't go to Wal-Mart for that stuff-- salon is always better.
I'd also like to suggest getting your hair treated every month. Go to your salon and ask for a smoothing treatment or something that'll moisturize your hair. It'll become more manageable with the treatments.
Good luck.
