I have been using this product for about a year and I can say that guys go for it.
It will definitely make your hair shiny.
You have to use tiny bit of amount because less is more for your hair and if you use little more it will make your hair look greasy.
Price is absolutely fine( 185 for 100ml bottle) .
Though it is not long lasting, you should use more than 1 application.
There two types available I think, one is walnutoil and second is pro hair. Both are good.
Smell is strong but fine.
