never heard of jojoba oil that needs to be heated. I’d definitely pass on that one. If you have a trader joe’s in your area they usually have it and fairly cheap too. If not any vitamin/nutrition store will have it, as well as whole foods.
you should always be leery of any oil thats specially packaged usually they have a base of silicone so they can stretch the oil. the result is nowhere near as good as real oil. you can usually identify silicones by reading the ingredients as almost anything ending ‘cone.’ but like i said before you want an oil that is just plain and simple oil.
