In the long run with consistent deep conditioning and minimizing manipulate damage and other damage from things like coloring, you can help save it to an extent. I suffered from overprocessing for a long time and in the long run, I had to cut most of it off. I would suggest a heavy protein treatment now and weekly deep conditioning treatments from here on out. Focus on minimizing the risk of overprocessing. Don't relax too frequently, wash and condition every week, don't use a relaxer thats too strong, base your scalp and protect the previously relaxed hair and only apply to the newgrowth.
