Review (3/5): Good Control But Be Careful
This product does provide very good edge control. However, it does cause build up and can lead to white film on your edges. I have found that washing it out nightly and reapplying it fresh tends to minimize that. Also, if you do not wash it out, it can cause some breakage, so even if you don't wash it out nightly, I would suggest not going more than 3 days without washing it out.
