Red light therapy masks and hair growth gadgets are no cheap shindigs, but Amazon Prime Day makes them more appealing. The Dr. Dennis Gross DRx SpectraLite Faceware Pro mask is a cordless marvel, perfect for quick self-care sessions—just three minutes long! For those with thicker wallets, the CurrentBody LED Hair Growth Helmet has seen impressive results, with testers reporting thicker hair and less breakage.

The Laduora Lumeo SkinLift 4D kit offers multitasking goodness, combining light therapy, microcurrents, and massage. It's a beast of a tool that delivers on its promises, even if it's hefty on the price tag. Meanwhile, the Laduora Duo hairbrush is a more compact option, with a flexible headband design for targeted treatment and faster regrowth.

Finally, there are current deals on LED caps and masks from CurrentBody, offering discounts of up to $20 off. WIRED testers have noted significant improvements in scalp health and hair growth with these devices, making them worth the investment if you're serious about your grooming game.
