once straight and nice, now kinked and lame

 

Before I started dying my hair, I could blow dry my hair and have it perfectly straight. I could sleep on it and wake up with it still perfectly straight. I started dying my hair and my hair stayed that way for YEARS. Now whenever I blow dry my hair, it kings and either goes in or out at the ends...leaving me to have to flat iron it straight, which leaves it limp and not very full of life.

 

WHAT CAN I DO TO GET IT BACK TO WHAT IT USED TO BE???

 

I've tried everything I could think of and I'm at a total loss.

 

PLEASE HELP!!
