Lovely! You should use Special effects or Adore, best reds on the market 🙂
I do similar with the hi lights magenta, red, copper ...then I use One and Only Perfect Intensity Magenta recently. ONO Red is more deep & "orange". I have PRAVANA & Special Effects the later is awesome. The magenta from ONO is lasting a month or more so far!!!it is gorgeous and I have to shampoo everyday because of being so active outside. 😉
Three things, 1: Your hair is amazing, 2: You are insanely gorgeous, 3: Is your user name a reference to frou frou lyrics or is that just wishful thinking on my part?
Also, yeah try special effects reds. They're great.
I used to get about 4-6 weeks out of Special Effects reds (particularly Nuclear Red) - they really spoilt me for other dyes!
