Castor oil has been used by our grandmothers and mothers. That it was used internally used as a natural laxative, but is not my area of operation. I confine myself to the great effect in beauty care. What woman (or even what man ?!) do not want to have beautiful thick eyelashes that surround the eye and let our eyes look more intense. Brooke Shields in the 80'ies and the new style icons Cara Delevigne and Duchess Kate have drawn with their dense and strong brows our eyes on the eyebrows. But what makes woman going from house already has a visible brunette eyebrow and eyelash, but is not happy with the density and thickness? She hopes for the miraculous effects of various sera that should conjure Klimperwimpern and miracle brewing. That these eyelash / brow serums are incredibly high priced and for manufacturers immense profit margins offer (High price with the lowest amount of product) is taken at the beginning in buying, because the desired effect would be ignore it. Luckily my well-tried castor oil fell again and after some research, I chose the 100% pure oil of "Naissance". I use the castor oil as follows: a disused eyelash brush I wear it after the evening on face care eyebrows and eyelashes on. One can also mix before shampooing with coconut oil and massage into the hair lengths and ends. I mix the castor sometimes drop by drop into my face serum and then massaged my skin intensely. This is especially in the cooler season an effective additional care. Castor oil is significantly thicker than other natural oils, making the application easier for beauty care in its consistency. The aroma is perfumed and slightly rancid. However, no unpleasant smell. Since it is a pure oil, could be essential oil scenting it with a few drops of a pure (!). After months of use I can see the effectiveness of my eyelashes and eyebrows: my lashes have become thicker and longer. Even my eyebrows grow back, even in places that had been through years of plucking lights. For sensitive eyes I would use very little oil while brushing the eyelashes, because it forms a slight film on the eyes. The oil is super productive and I have just used up half of the bottle contents, despite intensive use. I can only recommend castor oil and especially this of Naissance, because it is a versatile and very acceptable natural product for a small price! The plastic bottle I do not interfere, as they cleaned is also reusable.
