I've been using the mini size for about two weeks to style my hair. It's just right for styling my shoulder-length hair in a slightly wet style. It's not too heavy or light, and it's not too sticky. I often get acne when I use it on my face, but this is just right for my hair. There's no strange scent to it either.
Since my hair is curly and difficult to style with a hair dryer, this hair oil is essential for me, as I mostly wear curly perms. After washing, I roughly comb my towel-dried hair, spread one dropperful of this product into my palm, and gently work it into my hair from the ends. Then, I let it air-dry. It creates beautiful perm curls, while leaving my hair feeling moisturized and non-sticky for a long time. Since styling products with various additives can become unpleasant over time, the fact that it's made with 100% argan oil is appealing. I try other brands of argan oil whenever I find one, wondering if it's right for me, but I always end up going back to JMO's. I once found a similar product online at a discount and bought it, but the feel was clearly different and it turned out to be a fake. Since then, I've made sure to buy it from official retailers or department stores.
I used the mini size as a hair oil and found it to be a little oily on my fine, fine hair.
I was looking for an unscented hair oil and finally found this. It works great even when I wear my favorite perfume, and it doesn't clash with my other perfumes. It's easy to use as an oil and can be used on the whole body, so I'm glad I bought it.
I received this as a gift from a friend a while ago and it was so good that I wanted to use it again after a long time, so I bought it myself, mainly for hair care. If you massage your scalp before shampooing, the next day it feels less dry, and your hair feels shiny and manageable. If you apply it to the ends of your hair after curling it, it won't be dry at night, even in winter! This time I'd like to try using it on my face too.
