Minoxidil products, whether they be foam or liquid, are accompanied by a supply indication which can cause some confusion. Men's Rogaine foam is sold in a 3 month supply which includes 3 60 gram cans. However, Women's Rogaine foam is sold in a 4 month supply version that includes 2 60 gram cans.
The reason for this is women's Rogaine foam is to be applied once per day as recommended by the manufacturer, whereas men's Rogaine foam is to be applied twice per day.
We hope to clarify the confusion with the table below. Although we have not included generic minoxidil products, they follow the same dosage guidelines for both foam and liquid.
| Product | Supply | Applications Per Day | Cans/Bottles Included |
| Men's Rogaine Foam | 4 Months | 2 | 4 |
| Women's Rogaine Foam | 4 Months | 1 | 2 |
| Men's Rogaine Liquid | 3 Months | 2 | 3 |
| Women's Rogaine Liquid | 3 Months | 2 | 3 |
