The hair is a little more soft and shiny but it is nothing revolutionary.
I would recommend this oil to that have dry and brittle hair, but pay attention to the smell a little bit high which make the somewhat unpleasant use. (For me the smell did not bother me and in any case it does not remain on the hair)
In short, the benefit / cost ratio deserves 3/5 as compared to the very high price of this little bottle, the result is that of a fairly basic product.
