Dye/Hair Advice - Which Dye and how can I better condition my hair?

Hi Guys!!

I have used all kinds of dyes on my hair in the past, but I had to stop due to career commitments. I have recently found a loophole in life, and can have some colour back in my life (Though its not my signature UV pinks any more  🙁 ) lol. I have attached photo's of what I currently have for a better idea (The pic doesnt do the red justice here, its slightly brighter)

My question is, I am a dye hard (Excuse the pun) SFX user, however, the colours I want doesn't seem to be in stock ANY WHERE (Admin... when do you restock SFX? :D)

What I am asking is, which dye (Other then my beloved SFX) and which red is the best red to use? I am looking for something a little on the darker side, such as a blood red, I want one which will last for a while, cause, as you can see from my pics, it will be hard to get all of it on a regular basis, but I want to keep it vibrant.

Also, my hair is really dry, what are the best shampoo's/conditioners/treatments to use on coloured hair?

Thanks guys 🙂
