I have a bottle of this that I ordered on a complete whim when MUAC had one of their sale codes. I was sure I would find a use for it, and now I have found two!
Let me preface by saying that I have thin, fine, straight hair. The fact that I can even use an oil on this hair is astounding to me. I found this tip by accident as it was!
One day I spilled a little of my oil on the bathroom sink. Not one to waste things (thanks, Mom!), I quickly wiped it up with my fingers and began massaging it into my cuticles. Okay - now rubbing it into my hands, forearms, elbows. Um...knees, heels...what else can I moisturize here? (Okay - I spilled more than a little bit.

)
Then I looked in the mirror and spied flyaway hair. Hmmm...very carefully, I patted the surface of my hair with my oily fingers. Perfection! I didn't touch it again the rest of the day, and I had shiny, swingy hair like I've only seen in magazine ads!
Now I can only do this on days I've shampooed and must use a tiny fraction of a drop. Otherwise, I should just wave the tightly-closed bottle in the vague direction of my head. Those of you with thick, wavy, curly, textured body-ful hair (and I dislike you intensely) could use more oil, I'm sure.
My little bottle will last me for all eternity.

(My other use for argan oil is on the Skin Care Board.)
