I have used this Argan Oil, it had arrived bubble wrapped and in dark brown glass bottle. They use a dark bottle to keep the freshness and potency in to keep the light out. It is 100% Pure USDA Certified Organic Argan Oil from Morocco. I used this after I shampooed my hair instead of using conditioner. It had said to use 1 to 3 drops and to leave in for 30 minutes and then rinse it out. I had used to much the very first time, Because my hair is really thick but you ,only really need 1 to 3 drops rub into your palm of your hands and rub into your hair and leave it for 30 minutes and rinse. It makes my hair silky smooth and took care of any split ends I had. I also used it on my finger nails.I used the go pure Argan oil, I rubbed a few drop into my hand and rubbed it into my nail beds , it helped me so much it made my nails grow and also soften my cuticles .I also like using it on my face. because my face because of the dryness in the air when having to use the heat, my face was more hydrated with the Argan Oil, and my skin was left with a dewy glow. It didn't leave my skin feeling oily which is a plus. It will also help to reduce stretch marks, and help with acne blemishes and scars .
