I have very damaged hair from showering and washing my hair almost every day because of being an athlete. Thus leaving my hair stripped of its natural oils and dry. I ordered this argan oil shampoo because of its restorative formula and absence of sulfate. The shampoo arrived in a large plastic 16 oz. bottle. The cap is a flip cap so access to the shampoo is really easy, even if your hands are wet. The shampoo has a light yellow color that smells exceptionally good. It is silky in your fingers and lathers relatively well. When using the shampoo, rinse you hair with water and squeeze a nickel size of the shampoo into your palm. Then massage the shampoo into the scalp through ends of hair. When finished lathering, keep the shampoo in your hair for a minute or so and rinse back out with water. Continue your regular shower routine. The shampoo moisturized my scalp and kept it from being dry and straw like. It left my hair really soft and I felt no greasiness. I am very happy I got this for my hair.
