Prose currently offers three products: a hair mask, shampoo, and conditioner. You don't have to get all three, and you can order more than one bottle of any product when you check out.
The mask lasts up to 10 weeks while the shampoo and conditioner last six to eight weeks. Each product's price will depend on your unique combination of ingredients, but start at $25.
You can also subscribe to automatic shipments (every one, two, or three months) for 20% off your order.
