The colour is annoying me too! After having to go from white/grey to having loads of root then brown ombre with blonde at the ends, I went back to a more natural blonde for my wedding but I'm still not really happy with the colour. At the minute I'm trying to force myself to just let my roots grow and finally get my hair back to my natural colour without needing to dye or highlight. I'll probably grow the roots out completely to my real colour and then be like "hmm, time to dye it."
As well as going for the chop and stopping using heated styling tools (I probably heat style once every 6 weeks if that - since it's been cut it needs way less styling to look good), I'm also working to find the right products for hair to keep it nourished and healthy. I'm using Ojon shampoo and conditioner, I've been taking hair supplements and I'm also using Kerastase Resistance Ciment Thermique Resurfacing Reinforcing milk when I blowdry after my hairdresser recommended it.
It's really good and helps protect my hair. If I blow dry it holds the shape much better. It smells great too (quite citrusy), feels really light in your hair and you only need a tiny amount so it's definitely going to last for ages. It's reactivated by heat so if you do use heat on it again it holds it in place, it also supposedly makes blow drying quicker but I haven't noticed that to be honest. I would definitely recommend this though, I've been using it for a few months now and I do feel it's made a difference to my hair.
As a kid I had ridiculously thick, shiny hair but after dyeing, bleaching, straightening/curling for about 20 years it's just a bit rubbish and I want to get it back to it's natural state.
