Not that Jack Black!
Size: 4 Piece Set
I bought this set assuming it was the actor/musician Jack Black’s skincare line. I figured a bearded celebrity would know all about quality beard care products. But actually it is not even named after a real person, it’s just a brand name. In fact, Jack Black the celebrity said he tried Jack Black products and they gave him a rash! Not a big deal though. I haven’t had such a reaction. The products smell fine, not overbearing, and seem to be working well. Cons: not exactly economical since it’s very small tubes. The beard oil pump is easy to overdo— Press too hard on the pump and you’ll end up with too much oil on your hands. A little goes a long way.

Wash/lube is travel/mini size
Size: 4 Piece Set
Did not realize beard lube and wash are mini/travel size but that’s my fault for not checking.

Never have I felt my beard this soft after using this beard oil…
Size: 4 Piece Set
I’m usually not the dude to leave a review on a product, but the second I hop out of the shower and tried the beard wash and beard oil, I was shocked.
Out of all the other beard oils and beard wash products i’ve used, this has to be the best result so far.
For the price, It can be expensive, sure. But it’s the only one you need. I don’t think i’ll ever go on a search for beard oil or wash ever again. This product is great!

Great kit for beards!
Size: 4 Piece Set
I had struggled with an itchy face/beard forever. Just thought my face was dry so I used lotion but it did not resolve the itch. Did some research and saw this brand recommended by multiple sites. I decided to give it a try.
Since using these products, my face/beard no longer itches! Shaving (cleaning up my beard edges) with the shave cream seems to feel much smoother too. It feels as it softens the hairs which then requires less effort to shave off.
Follow this up with the good and lightly scented beard oil to leave a smooth feeling, no-itch beard.
Would definitely love bigger sized containers but I would definitely recommend these Jack Black beard products.
