this oil is of excellent quality! a little higher delivery costs but it is worth it, a package would be welcome when you buy more products from this brand. Castor oil has many properties, it removes age spots (starting three months of daily use), it facilitates the regrowth of lashes, it nourishes the hair ... Castor oil is the best oil I know for thick, curly hair like mine. The day before the shampoo, I pour the oil into a cup and then I pass the oil on my hair with my fingers, strand by strand, for good kneading (the length, do not bother to put on the scalp ), I attach my hair, I let pose all night and the next day I do my shampoo: result: gorgeous hair soft, nourished, bright brief I recommend !!!
