From the Orofluido website:
Argan oil: liquid gold for your hair
Extracted from the seeds of the Argania spinosa fruit, Argan oil is rich in vitamin E and essential fatty oils, similar in composition to our own skin. It strengthens hair and makes it extremely light and incredibly silky.
Linseed oil: instant shine
The seeds of the linen plant are the source of a precious oil which seals and smoothes the hair cuticle, providing uniformity and control. The result is hair that captures and reflects the light, giving it a spectacular shine.
Cyperus oil: pure silk to the touch
Cyperus is a plant that has been cultivated in Egypt for more than 4,000 years. It is the source of an oil with a high content of fatty acids and tocopherol, which give natural protection against free radicals. It provides softness and volume, leaving hair manageable, smooth and flexible.
It retails for $29.99 on the Birchbox site, that is for a 3.4 oz bottle, which probably lasts forever. I would buy the full-size.
