Ok so I am a brow enthusiast, and have always used MAC Spiked on my brows...purchased Deep Dark Brunette and I am soooo happy with the results. I always hated regular fluidlines in brows, but these are so much softer and way more natural looking. I have dark brown eyebrows, and this worked perfectly with my trusty 208 brush and gave them the definition that I wanted. I have pretty thick brows so I always outline the bottom of my brow softly and bring any remaining product through the rest of my brow. I will definitely be ordering a few more of these, and praying that MAC makes them permanent!
