As far as my knowledge goes I think jojoba plants are found in California, Arizona and Mexico.
It is a plant that can grow up to 15 feet high and the oil is pressed from the seeds or you can say nuts that grow on the tree. Jojoba oil is not actually an oil, but a liquid wax.
It is good for you because it closely resembles human oil, so the uses and benefits to skin and hair are high.
At first I was comprehensive about using this oil on my skin as my skin gets oily during the night. However jojoba oil regulates the amount of oil your skin makes, creating less oil.
You can use jojoba oil as a body or facial moisturizer. A little goes a long way! It is also good for removing makeup, especially waterproof eye makeup
It is great for cuticles too. A drop of jojoba rubbed into the nail bed makes for a great moisturizing treatment for dry cuticles.
You can use it as a hair mask prior to washing or a bit applied to hair after washing for dry hair to reduce the frizz. It is very beneficial for dry hair.
You have to use a little bit so a little goes a far way, also it in inexpensive.
