Review (3/5): Not worth the current price
I've used a number of Jack Black products over the years, but this was my first experience with the MP 10 Epic Moisture oil. I have a short (7mm) beard as well as a short haircut, and tried using the oil on both as directed. Overall I didn't find it to be bad but also didn't feel that it lived up to its price.
There are three things I liked about this oil. The packaging and bottling was very good. It comes in a well-made glass bottle with a good pump. I found the instructions to be detailed and precise. I also liked the fact that the scent was almost nonexistent. Some reviewers say it has a faint lemon/citrus smell. It reminded me more of a glass of water with some lemon wedges in it. Overall, pleasant.
What I didn't like was the texture of the oil. It was rather thin compared to other beard/hair oils I've used and seemed like it required about twice as much product. While it didn't leave a greasy feeling on my hands, or in my beard or hair, it also didn't provide much in the way of moisturizing/softening. Again, it was fine, but not "$35 per bottle fine."
I've used two other beard oils on Amazon which I felt were a particularly good value: Gibs, and The Art of Shaving. Both have stronger and more nuanced scent profiles, but both are thicker and have much better moisturizing properties. I'll continue to stick with those.
