Pretty sure those side effects are for when it is taken internally, as they say that taking it with food reduces them as opposed to on an empty stomach.
The only side effect I have ever had from applying oil on my hair and scalp was when I used avacado and it gave me a migraine. Turns out I'm allergic to it. If you are using your mix and it works for your hair and you don't get itchy scalp or migraines then I see no reason why you shouldn't continue!
