Split the Difference

I went blonde a year and a half ago and in retaliation my hair is dying a slow and painful death from the tips up. It is splitting and cracking like a patio in a hurricane. Tying itself into knots.

So now I am hair obsessed and wondering how I can keep from looking like this:

And when will my hair be healthy again?

I can kind of relate to Freida Kahlo in moments like this.
