How much ritual fits in 16 ounces?
Bottle life depends on hair length, density, frequency and whether you share it.
The four factors that determine bottle life
No honest estimate can ignore how the oil is used. A long-haired user applying full treatments three times weekly may use several times more than a fine-haired user treating once weekly. The 16 oz format is best understood as a generous consistency size.
Application type
Finishing drops use far less than a full pre-shampoo treatment.
Hair length
Longer lengths create more surface area to cover.
Hair density
Dense hair requires more sections and often more total product.
Household use
A shared family bottle naturally empties faster than an individual one.
Measure your routine—not someone else’s.
Note the bottle level before your first treatment and again after four comparable uses. That gives you a far more realistic estimate than a generic number.

- Repeat the same type of treatment four times.
