Weekly deep conditioning - could be any regular conditioner, just leave on for an hour, and add heat. Bi-monthly protein treatments - Nexxus Emergencee from CVS or Colorfill protein filler from Sally's (cheaper). Weekly or twice weekly oil treatments, with heat. Olive oil is fine. But of you have a color over the blonde, oil will make it fade. Shampoo only once or twice a week if necessary. Use a sulfate free shampoo if possible. And condition often.
It's a lot of work to get the life back.
