For 4 years??? Didn't you get it dyed over properly by a hairdresser? You poor chook

It looks way better then it did before I put the brown over it that's for sure but I think it's probably that green shade of brown you can get if you don't add red back rather than a normal shade of brown iykwim.

What's even more annoying is that it feels yuckier too due to the drying out! Oh well I have been blessed with 'pantene commercial hair' all my life so it may seem worse to me than it really is... I guess the last 2 years are just me having my share of bad hair days!
