Here's my hair before dying, The last time I dyed it was December 22nd in my local hairdressers.
Please excuse the face my hair wasn't washed and the white bits arn't dandruff, it's psoriasis.
And here's several photos of the result.
For a semi permanent I think it worked out pretty well, some greys were missed but overall it's a lot better than what it was. The smell wasn't too strong but my hair was a little bit dry afterwards, normally I put in more conditioner.
