How do I apply the Woohoo Deodorant Paste?Updated a month ago

With clean, dry hands, use the tip of your index finger to collect a pea-sized amount of deodorant and warm it on your fingertips.

Rub half of it under one arm until it disappears, just like you would a moisturiser, and repeat on the other side. That's the starting point rather than a strict rule - plenty of people use more, and how much deodorant you actually need has the range.
