The lifespan of a bottle of shampoo can vary depending on individual usage and the size of the bottle. On average, a standard 12-oz bottle may last about 1 to 2 months for daily users, while those who wash their hair less frequently might stretch it to 3 months or more. Factors such as hair length, thickness, and the amount used per wash also play a significant role in determining how long a bottle will last.
