I have had dry skin for a while and I read about people using coconut oil. So I tried that on my face and on my hair and I found it too heavy. I also read about people using jojoba oil and it is perfect! It absorbs quickly into my skin and keeps it moisturized all day long. I use a couple of drops with my co-wash conditioner and it keeps my curls nicely hydrated.
I got a 4oz bottle from trader joes for $5.99, which i think is a good price, especially since its far less than I would pay for a good moisurizer from a drugstore. But you can shop around and maybe find a better deal.
