What is it: Jojoba Oil is a liquid wax and ester extracted from the Jojoba seed. Also known as goat nut,deer nut,pignut,wild hazel,quinine nut,coffee berry, and gray box bush. (Wikipedia). Jojoba oil is a straight-chain ester which makes it closer to Sebum and Whale Oil than to vegetable oil. Note: Sebum is a thin layer of oil that is naturally produced by the human scalp, It contributes to the hairs shine and flexibility.
Where does it come from: The Jojoba plant is indigenous to the Southwest United states. Think So-cal and Southern Arizona. The plant prefers a sub-desert climate with tons of sun light.
Benefits for Your Beard: This oil is temperature neutral, which means it is liquid at room temperature, so it shouldn't solidify on you. It is most commonly known to add an amazing shine to your beard and really relax the wild and crazy hairs. Jojoba is also known to eliminate acne when used on skin. So, you are very unlikely to get a beard pimple while using a Jojoba bearing product.
Negatives For your Beard: This oil is extremely potent. From the brewing the oils, it mixes very well with other oils but only in small doses. We never mix a beard oil recipe at any more than .05 or 5% of the total. If you read into the sebum link above... "A little amount of sebum can produce a healthier fuller look, but to much can predominately damage hair". So basically, A little goes a long way!
Other Notes: Jojoba Oil can be great for hair in small doses, but you should be weary of beard oils that list it first on their ingredients list. You can immediately tell when a product contains to much Jojoba by how "greasy and saturated" you beard stays, minutes and even hours after applying.
For The DIYers out there: When looking into using Jojoba oil for your own beard oil/wax, remember to look for 100% organic and really try to find "Cold-Pressed" brands.
