There are plenty of reasons that brow henna has become one of the hottest beauty trends, especially among celebrities and beauty influencers. Here are just a few of the perks you can look forward to: Forget the painstaking process of filling in your brows every morning – and the expense of constantly trying new brow products – henna brows will change your routine for the better.  Instead of dealing with the frustration of lopsided, sparse, or graying brows, you can have a perfectly filled-in look with absolutely no effort. You can easily skip makeup in the morning for a fresh-faced look, and your henna brows will ensure that you always look put together. Henna brows can be a good way to test out a certain brow shape before committing to a more permanent procedure.
