Works great & smells good!
Scent: Sandalwood
I was concerned the facial wash would be too harsh but thankfully I was wrong. Every part of this kit compliments the other. My skin and beard feel noticeably softer, and I haven't had any acne breakouts. The scent is masculine but not too strong. This is now my new routine.

Smells amazing!!
Scent: Sandalwood
My husband loves this set. He has sensitive skin, and loves this product since it doesn’t cause any irritation, plus it smells amazing! The face wash seems to be helping with beard acne, while not drying out the hair like other washes do, and the oil moisturizes well creating a healthy shine. I would say this is well worth your money if you are looking for a full starter kit to try something new and well-rounded for your beard care.

Great product at great price...
Scent: Sandalwood
As someone who's had a beard off and on for the better part of a decade, I've gone through my fair share of beard products. For the most part they're all very similar. The washes for the most part clean and leave a very squeaky clean (almost dry) feeling out of the shower. Conditioners help a bit after a wash, but not anything to write home about, the only one I've tried that I really liked was Scotch Porter. Oils help in hydrating, some are excessively oily and just don't look very appealing. Balms will help tidy up the overall shape of the beard, some are not really strong enough and just end up being another layer of oil on the wiskers. Ok, now for this review... So I believe this to be the most natural and most effective line of products I've found to date. First off, the wash, oh my, the wash... I could really just stop right there. This is my favorite of the line. It leaves my beard so soft I find myself not wanting to ruin it with a conditioner. If you try just one of these product, the wash is a must. Next we have the detangler, this is pretty much a leave in conditioner. It softens out the beard even further and adds a slickness to the beard, it feels great. The oil in the set is probably unnecessary since the wash and detangler do such a great job, but in any case it is a quality oil. The reason I say this is because it doesn't really stay oily in the hair, you can feel that after initially applying, it does absorb into either the follicle or skin, whichever it's intended to. As I mentioned, there are some oils that just don't do that, it's just greasy all day long. The balm is probably my least favorite of the line, but only because it's not a very strong holding balm. It's kind of like I mentioned, another layer of oil. This one does also absorb so it's ok. I prefer a more tacky balm with more wax rather than oils. Also, the scent of this line is a subtle chocolatey vanilla kind of smell. It's a very pleasant scent that my wife also enjoyed initially. However after about a week or so of using the product, I no longer get so much as a whiff, which is fine, I find that to be common with many of these beard oils and such. So, overall a great set of products that leave my beard feeling soft and hydrated all day long, it also feels like quality, in the sense that it does absorb. It doesn't feel like you just applied baby oil all over your face. I cannot stress this point enough, there are some "name brand" beard care product that feel as such. That's why this product line really stands out to me. Five stars...
