This ultimately depends on how long your beard or scruff is.
For a beginner beard (fresh scruff to about 2.5 months) our 1 oz. beard oil lasts between 2-3 months.
We recommend a daily application to help moisturize your hair and skin as well as ward off
that dreaded beard-itch. For a more mature beard with 3+ months of growth, our 1 oz beard oil lasts 4-5 weeks.
With more mature beards, we also advise the use of our beard balm in conjunction with our oil as a part of your normal beard care
routine in order to moisturize, protect, and keep those longer stray hairs tamed.
