Like all 'naturals', it takes a period of getting used to it. And it often requires you to reapply more often at first. But eventually it will be less and less. Much of this depends on your diet, exercise routine, etc.
Using deodorants and antiperspirants with aluminum on your armpits (like in Secret, Axe, Old Spice, and even some Tom's of Maine deodorants), is great at blocking sweat but terrible for our bodies. It's incredible at absorbing odour and sweat on contact without clogging sensitive pores.
