Eylure Dylash Eyelash dye kit: review

Eylure Dylash Eyelash and brow dye kit - Dark Brown

I have always been the kind of girl to do her beauty treatments at home, as much as possible. Firstly to save money, but it's also a sense of independence and accomplishment, not letting my eye sight get in the way!
The only 2 treatements I wouldn't do myself are dye my hair(mainly because I do 3 times a year, and it's the only 3 times a year I go to my hairdresser's) and tint my lashes. I used to go to a salon close to my place and get it done there.
Then I realised it was very easy, and for the same price of one tint at the salon, I could buy this kit that supposedly lasts you qite a few applications.
I bought this a good while ago, but because my fashion show in Italy required me being all natural, I couldn't put it to the test, until now.
Well....let me tell you, it was a big fat fail...

Here's the before photos:

I followed the instructions perfectly, and actually left the tint on for 15 minutes instead of 10 because any kind of dye on my hair/lashes takes longer to develope.
I was actually happy that it didn't sting as much as when I get it done in the salon, that was a plus!

And here's the results....


...not exactly the dark brown I was expecting...

And now I'm left with the kit and I don't know what to do with it....? Shall I just throw it away and try a darker tint? Or finish the whole thing anyway because I paid for it?

What do you guys think?
