To estimate how long a 50ml sea salt spray will last if used once a day, it depends on how many sprays you use per application. Here’s a breakdown:
- Typical Spray Usage: A sea salt spray bottle generally releases about 0.1-0.2 ml per spray.
- Daily Usage: If you use 5 sprays per day, that would be about 0.5-1 ml used each day
The quantity in which you should utilize sea salt spray will range count on your hair kind and the frequency of oil your scalp biologically produces.
If your hair is excessively oily, utilizing a sea salt spray every day likely won’t induce any problems.
If your hair is more on the dry side of the spectrum, we’d suggest holding the bottle on the shelf a few days a week to permit more of your natural oil to build up between uses.
At the very least, you should give your hair a thorough rinse and conditioning between uses of any spray.
Calculation:
- 50ml bottle ÷ 0.5-1 ml per day = 50-100 days.
Thus, a 50ml bottle should last between 50 to 100 days if used once daily, depending on how much you apply in each use. If you use more or fewer sprays per application, the duration will vary accordingly.
