Jennifer Lopez's favorite shampoo is on sale for the lowest price we've seen all year

The hero Olaplex product started as a salon-only treatment, but during the pandemic was made available to its devoted fans (including Margot Robbie) for at-home use. Kim Kardashian loved the hair-softening, hair-strengthening effects of this formula so much, she once used "Olaplexing" as verb. 

This spray (No. 0) is the first step in a two part system with the Hair Perfector (No. 3). Listen, this math doesn't make sense to me either, but according to 14,000 5-star reviewers, this is a "miracle product." One said: "This is the best product to use if you have damaged hair especially if you use color. It has helped my hair grow longer and stronger."

Cunningham told the New York Post she uses Olaplex's fortifying shampoos on all of her clients, including J.Lo.

Aside from their fab price (over 40% off!), we love the real-time power readout on the front of the case of these earbuds, making it so much easier than pulling out your phone and swiping to find out how much charge is left. The top number shows how much juice is in the case, while the two smaller indicators show readings for each bud. Pretty smart! But that's not their only innovative feature: These buds have everything you'd expect in a quality pair. On-ear controls let you answer calls, skip songs and activate Siri. They also have multiple sound modes to pick from. Nearly 8,000 five-star fans can't be wrong, right?
