What's the best deep conditioning treatment for over processed hair?

I made the mistake of having a new stylist color my blonde hair red. This was last August. I hated it. After giving it a try for a few months, I decided to go back to blonde. That's not easy to do with red in your hair. My hair has been heavily highlighted over the past several months. Yesterday my stylist decided to try doing heavy foiling to get rid of the rest of the red. It didn't work. I still have some red in my hair so she decided I needed a golden toner to blend it better. I don't like the golden blonde but at least it seemed to fade a lot after washing it today. My big problem now is it appears she damaged it this time. I lost enough hair in the shower this morning to clog the drain. Then while blow drying I got hair all over my clothes. What should I use to repair this damage? I already use the Aveda damage remedy shampoo and conditioner so I'm looking for something to use as a damage repair and/or deep conditioning treatment. Thanks in advance!
