Well, I bought some AOS pre-shave oil but haven't been too happy with it. It's way too thick. In the meantime, I decided to change my routine a little by doing WTG and XTG with TOBS Sensitive and then using Shave Secret for ATG. To make a long story short, I found in a book I won't name a "recipe" for making what seems like a very good quality shaving oil which I would like to use for that ATG pass. The ingredients are: almond, avocado, macadamia, olive and grapeseed oils and lavender essential oil. I've found everything but the macadamia nut oil and frankly am not interested in searching anymore. I wrote the author to ask how he would re-proportion the ingredients if he were leaving out the macadamia nut oil but never heard back from him. So, my questions are: 1) is macadamia nut oil essential to a good shave oil? and 2)if you had these ingredients (almond, avocado, olive and grapeseed oils and lavender essential oil) in what proportion would you mix them to create a good shave oil? (I know that one would only use a drop or two of the lavender essential oil.) Thanks, Guys!
