Color oops, protein filler... or both?

 

I have been coloring my own hair for about a year and a half now. I have seriously dark brown hair and have been using a hi-lift brown- a boxed Feria color called "downtown brown", (I now know that Feria is not the best color to be using). The last time I used the Feria it left a grey tinge to my hair and I was freaking out about it, but it dissapeared after a few days/washes. I decided I wasn't going to use that brand anymore since it seemed everytime I dyed my hair it turned out a different color. I really have noticed that it has become more of a blonde rather than a "light brown" and decided I was going to go a shade or so darker to make it look more natural. I used a different brand haircolor and the results were much better. I had a nice even brown color again (it was a little darker than I wanted, but I figured it worked).  Well the color has washed away and I am left with the blonde color again (from the previous dye's of feria) and my mega dark roots(I have been trying not to color).

 

I have long hair which reaches just below the bottom of my bra and I have noticed that it seems to be somewhat drier than I would like it to be, SO my questions are.... should I use color oops to get the color back to it's lightest natural color(I don't want it to turn orange), is color oops harmful to hair(will it dry it out more if i use), or should i use a protein filler to strenghthen and mend my hair before the next hair dye, or should I do both? I honestly had no idea such things existed so i'm not really sure if they are right for me or not, but it sounds like my hair might benefit from them.  

 

Thank you!

 

I bought loreal's nature therapy from Sally's(I wanted to buy everything there) on Sat. and tried it out and it is ah-mazing. Thanks for the tip!
