It's absolutely do-able for anyone!It sounds... do-able even for people never preparing homemade stuff, like me.
What kind of oils do you add, special skin-oils? And how much, or what is the proportion?
Yes make sure you use organic essential oils that are safe for using on the skin. The oils are optional, and you can really use as much as you want - but I usually go for 10 to 20 drops per 100 grams. Or something like that. Sometimes I add a few more after a few weeks, because the scent fades.
The smell won't really stick to your armpits anyway, it fades quickly. But some ssential oils have also an anti-bacterial function.
