I ran out of my Oscar Blandi dry shampoo recently and was upset to see that it was out of stock at ulta and amazon. So I did some googling and found a youtuber (doitonadime) who recommended regular old baby powder (cornstarch only).

I am now on my THIRD DAY of not washing my hair, and I'm thrilled at the time it saved me in the morning.

But an ad came up for Living Proof dry shampoo, and the reviews look amazing. It is a lot more expensive than the $3 baby powder which seems to be working just fine for me.

I wonder if anyone has tried both and can weigh in on whether the Living Proof stuff is really different:
