Didn't work waste of £9.99

I was really looking forward to using this & seeing the results as my eyelashes are naturally blonde and I regularly get them professionally tinted. I brought this in black from my local pharmacy. Sadly it seemed to make absolutely no difference once washed off even though I followed the instructions. I tried it again a few weeks later (as you get a few applications in the pack) yet again nothing 😞. Sadly I have to say it appears to be a complete waste of money & I won't be buying again
