Spiced Gingerbread Refillable Roll-On

Neither is better: it's down to what you prefer. A spray is quicker to put on; a roll-on gives you a more controlled application. Both are refillable, and both are a handy size to take with you.

Sprays and roll-ons refill the same way:

1. Rinse your empty bottle with water and let it dry completely.
2. Shake the refill bottle or pouch so the ingredients are evenly mixed.
3. Pour it into your bottle until it's nearly full. Do this over a sink: the natural salts can mark some surfaces.
4. Screw the spray cap or roll-on head back on tightly.

Up to 3 from a 300ml or 225ml pouch, up to 5 from a 500ml spray bottle, up to 7 from a 525ml roll-on bottle, and up to 10 from the 1 litre unscented spray refill. See how refills work.

Potassium alum is a mineral salt with a long history as a deodorant. It's in our sprays, roll-ons and crystals, and it's the only ingredient in our crystals. It isn't the aluminium chlorohydrate used in antiperspirants, but it is an aluminium salt, so we don't call those products aluminium-free. An antiperspirant temporarily plugs sweat ducts so you sweat less; a deodorant works on the skin's surface, where odour forms, and you sweat as normal. More on our ingredients.

Yes. The aloe vera leaf juice powder we use is organic and decolourised.

None of them are: anyone can wear any of our scents, so go with the one you like. If you'd like a starting point, men most often choose Vetiver & Citrus, Amber & Sandalwood, Oud & Bergamot or Unscented, and women most often choose Lavender & Vanilla, Peony Blossom, Clary Sage & Mint or Unscented.
