I've been using Jojoba for my hair after showering before hair drying for many years now. It's inexpensive, good quality and works well. I used the other brand by Leven Rose before. They are on par with each other. I started using this just to try it out as they are nearly the same price. I find this one has a mild meaty scent, like beef jerky or something. It's very mild but can turn some people off. The one by Leven Rose had more of a nutty scent. I highly recommend both.
My nails would crack and peel constantly. Jojoba oil hydrated my nails to make them stronger. In just 3 months I saw a great improvement.
When I needed a refill, I tried another brand that was decently cheaper. It did not work at all (it may not have even been jojoba). My nails started getting worse again. And my face broke out more when I used it to moisturize my face. I would definitely recommend this over the cheaper alternative because I know this one works.
