A practical decision
Compare shampoo and conditioner value fairly
Compare both bottle costs and their labelled sizes at ordinary prices. The lowest bottle price is not always the lowest volume price, and a pair total does not tell you a monthly cost.
Use the same basis
For liquid bottles labelled in fluid ounces, divide the ordinary bottle price by fluid ounces. For a pair, record the two bottles separately before adding their purchase costs. Do not treat a weight ounce as an equivalent fluid ounce.
| Item | Bottle price | Volume | Price per fl oz |
|---|---|---|---|
| Verb Ghost Shampoo | $22 | 12 fl oz | $1.83 |
| Verb Ghost Conditioner | $22 | 12 fl oz | $1.83 |
The manufacturer listed each 12 fl oz bottle at $22 on November 8, 2026: a $44 two-bottle purchase before tax or delivery. This calculation does not assume that you use equal amounts or finish both bottles together. Check the shampoo and conditioner sources before buying.
A useful lower-spending decision
Compare the EverPure Moisture pair in the root comparison, using current sizes and ordinary prices. If one of your current bottles already works, retaining it may reduce the amount you need to spend more than buying a discounted complete set.
