Product description

When Sheena made Air Brow - Clear, she was so impressed by the improved appearance of her natural brows, she wanted to make a version you can wear overnight (without the definition and hold of the brow gel). Sheena and the Kosas team added 6x more powerful and effective hair-boosting actives so brows + lashes could reach their fullest, fluffiest potential.
