Last into the tank is NOHBO seeking $100,000 for 20 percent equity.

NOHBO offers an eco-friendly option to shampoo: selling bottle-less shampoo in an environmentally-friendly ball form. The shampoo ball is wrapped in a plant-based material, according to their website.

Hyatt was interested in samples of the shampoo, but he had none to send. They are hand-pressed by a chemist. There is a space for possible licensing, as well as more of a mass production. It is patent pending.

Social reactions from NOHBO’s appearance on Shark Tank:

Lori Greiner says she’s impressed but thinks there’s some perfecting to be done so goes out. Kevin O’Leary goes out as well.

Robert Herjavec offers exactly what he’s looking for, contingent on receiving a patent.He wants to license it. Mark Cuban then jumps in, offering $100,000 for 25 percent. Barbara Corcoran offers the same deal as Herjavec, contingent on a deal with Estee Lauder.

Ultimately, he accepts Cuban’s deal.

Final deal: Mark Cuban for $100,000 for 25 percent equity.
