argh, I typed a whole thing and my phone died!
Anyhow, I use hair oil blends containing argan oil. I have two:
amika: oil treatment for the hair "Obliphica with Argan oil"
Exquisite Oil by Biolage "...a versatile serum infused with Moringa, Macadamia and Argan Oils."
I have long (mid back) wavy hair, and a lot of it. I use about a dime sized amount in damp hair before drying. It really does keep my hair from looking or feeling dried out and it definitely keeps frizzies away. Sometimes I use some in my hair before bed - I work it through with my fingers, then twist my hair into a bun and in the morning my waves are really nice. I generally avoid near the scalp, and focus more on the ends. Both of mine have a fragrance added, and they are both really mild, slightly sweet smelling.
After I run it into my hair I rub it into my hands, especially the cuticles - its a good moisturizer.
