Absolutely! I have nearly no eyebrows, but the pencil in this kit very nicely duplicates the look of natural brows. I think the serum is bogus, but it serves as a good prep for the brows, although I've used the pencil without the serum, as there's no big difference. The brow gel sets the finished work nicely. However, the product does wipe off easily with sweat, whether you use all three as suggested, or just one or two. I travel with the pencil on hot, humid days.
No. I tried this product and do not think it wears well. In addition, if your brows are dark, the brunette color may be too light. It is definitely a brown and not suitable for brows that are nearly black.
