Washing your hair every day is so passé. In 2015, we’ve all heard that too much soaping up can strip hair of natural oils and leave tresses dry and brittle…or strangely send them into oil-production overdrive.
But did you know you can sometimes forgo shampoo in favor of baking soda? Here’s the lowdown.
Wait, why do I want to do this again? Unlike shampoo, baking soda won’t mess with your hair’s natural pH—making locks shinier, less oily and all-around healthier. Some folks also report fewer hairline breakouts and thicker hair over time.
Do I just dump baking soda on my head? Nope. Fill a cup with one part baking soda, two parts water. When you’re in the shower, poor the mixture directly over wet hair, starting at the roots. Kneed it into your scalp and let it sit for three minutes before rinsing.
And then what? Follow up with your normal conditioner on the ends or an apple-cider-vinegar rinse.
How often? Two to three times a week.
Remind me how much a box of baking soda costs. About $1 a pound. Word.
