I'm fairly new to the world of Argan Oil at home. My stylist always used it and my hair looked great for a couple of days after my blowouts. It wasn't until recently that I had the opportunity to try Havens Arc Argan Oil in exchange for my unbiased opinion.
The Haven's Arc Argan Oil is very light - a much lighter consistency than other brands I've tried. Even the aroma is lighter than the scent of the brand my stylist used.
I find that when I rub just a couple of drops of argan oil onto my hands, then through my hair, my blowouts last much longer. If I leave my hair to dry natural, I can rub a few drops through the following day to tame my bedhead and still look presentable.
I prefer to not use oils on my face, but I love using argan oil on my hands and cuticles. My nails, after going through several months of breaking, are finally starting to show signs of growth and greater strength.
