Best Clay for Natural Look and Feel!
As a hairstylist with a very strong focus on men’s hair for over 20 years, I applaud the guys at Highland for what they are doing. A product line with quality and minimal ingredients we can actually read and understand. This clay is what I have always wanted!! Sure you’ll see some reviews talking about how there isn’t enough hold or it’s not even a medium hold when it says it’s strong hold on the package, but you have to understand, when a product is this clean, strong hold isn’t going to feel like the strong hold in the garbage products most of us have used. This is a strong hold, in terms of keeping your best natural look all day. Something you can work into place, then continuously run your hands through all day and it still looks great. The men’s clay from Davines does a wonderful job at this too, but there’s something about the finish of this product that literally brings out such a healthy natural look. Not shiny either and definitely does not give you a wet look out of the shower. If you see that kind of review, the guy most likely has greasy hair, is using cheap conditioner, or perhaps applied too much. Don’t over use this product in your application, you get the best out it. Amazing work Highland, keep it up!

Amazing product, definitely recommend!
Initially I was very skeptical about buying this product and kept talking myself out of it, did that a few times. I was under the impression that this was just an incredibly well orchestrated marketing campaign(it kept popping up all over social media) and people just out there overhyping it all. Yesterday I finally decided to give it a try and I have to say, BOY WAS I WRONG, this is probably the best hair product I’ve used in 15 years. Gives a natural matte look to your hair, it’s not greasy, gives plenty of volume and holds your styling in place in a very natural manner. The product also smells pretty good, HIGHLY recommend if you’re having doubts.

It delivers, but damn is it expensive
This product mainly shines because everything available at a brick and mortar shop is terrible - at least for men. This is great stuff, great hold without being greasy or turning your hair into spikes. No pungent odors. It's noted that it includes pine and sandalwood oil. There's definitely some pine, not getting any sandalwood. Regardless, it isn't a strong scent and that's how it should be. The tin is almost exactly the size of a snuff can. Expensive. But you don't really use much of it at one time.

2 complaints, otherwise great
This is a mostly great product. I only have 2 complaints - it’s really difficult to wash out, and the price. In my experience shampoo alone will not wash it out at all. Two-in-one products don't work. I have to use: 1. a shampoo 2. a conditioner 3. a shampoo again 4. More conditioner It does a really great job compared to other clays. I have short somewhat thin hair and it provides volume. It gives me the hold. I need all day. It smells great and it’s easy to work with. I wish it was cheaper. I feel like I’m paying extra for a cool looking tin. All that being said, I will be repeat customer

Just Okay...
This is an okay product. It works well for the first hour or two but then makes my hair very greasy - it feels like I haven't washed it in weeks. It's fairly sticky, which is great, but again it only lasts 2-3 hours for me before making my hair greasy. It smells great - I'll give them that. I'm glad it works for others but it's just not right for me.
