I have naturally red hair and wanted to see if it would boost the colour a little as it tends to lighten in the summer. Unfortunately I saw no difference to the colour and it didn’t really affect the condition of my hair either. If you have maybe blonde or dyed red hair I can see that this might work but for naturally red hair I would miss it! 

I have tried a number of leave in shampoos and conditioners with varying degrees of success. I have natural ginger hair and often 'redhead' conditioners have an alarming amount of pink in them! I end up with radioactive looking hair if I am not careful! My hairdresser advised me to try a copper conditioner. I first used devines copper conditioner - but although it gave me a nice colour it didn't actually condition my hair. So I tried this and I love it. I use it once a week and have lots of compliments on my hair colour since using it. I now combine it with a redhead shampoo (Jojo) and I find this gives me just the right shade. It is expensive - but worth it for maintaining your ginger awesomeness!
