Talk about impressive: In 2013, recent high school grad Lani Lazzari appeared on "Shark Tank" and wowed billionaire Mark Cuban into investing in her line of all-natural scrubs. She now employs more than 20 people! Our top pick from her brand is the Simple Sugars Green Tea Facial, $19, which is gentle enough for everyday use and offers antioxidant protection.

TBH, we were kind of over natural deodorants — until we watched Jess Edelstein and Sarah Ribner extoll the virtues of their PiperWai Natural Deodorant, $14, on a 2015 episode. The natural, aluminum-free cream deo relies on activated charcoal to curb odor and absorb moisture. A natural deodorant that nixes smells and sweat? Sign us up.

Those of us with curly hair know how difficult it is to reign things in — and gel often leaves strands crunchy. That's why our ears perked up when we heard hairstylist Alanna York describe her Controlled Chaos The Original Curl Creme, $24.99 on "Shark Tank" in 2016. It leaves curls frizz-free, shiny and smooth sans any stiffness.

A bikini wax is a summer must-have for many of us — but it often comes with a side of pain. Leave it to an anesthesiologist to come up with a fix. Edna Ma, MD, brought her BareEase Prep Kit, $10, on a 2013 "Shark Tank" episode, explaining that the cream works by temporarily numbing skin with lidocaine so that you can wax to your heart's content without the discomfort. The kit also comes with a latex panty that helps the cream absorb.

Cutting your own hair sounds like a recipe for disaster, but not so with CreaProducts' innovative CreaClip, $23.44. Appearing on a 2016 episode of "Shark Tank," inventor Mai Lieu showed how her hair tool could be used to DIY a haircut with ease. Snap on the tool (there's one for bangs and one for the rest of your hair) and snip off the excess for an even cut — it really is that simple.
