In the past I have used 1000 hour dye kits (in Australia). I recently moved to Canada with my husband and had to find all new brands. I used Swiss Opar Eyelash and Brow Dye Kit and it works fairly well. It is very easy and quick to apply - but you have to be careful not to use the comb provided in the kit when doing your brows (I used it the first time and had much thicker brows than anticipated). The dye works instantly, so you also have to be careful about not getting it on your skin - because it takes a few days to come off. I recommend using vasoline to outline your brow first to avoid dying your skin.
Was a little disappointed at how fast it fades - I am used to only having to tint my brows every 4-6 weeks, but this product faded after only 2-3 weeks.
