Is it waterproof enough for shower use?

It is water-resistant rather than fully waterproof. It can handle splashes and light shower use, but do not submerge it.

How long does the battery last?

Battery life depends on the speed setting. Expect several sessions per charge at low speeds and noticeably less at the highest levels.

There is no strong evidence that scalp massagers grow hair. It is best treated as a relaxation and scalp-stimulation tool, not a treatment.

It adds motorized rotation and adjustable speed, which is easier on the hands. A manual massager gives firmer pressure for less money.

It is designed for the scalp. The rotating heads can be used on the neck, but the light pressure limits how much relief it gives.

Typically the massager, a charging cable and a user manual. Check the listing for the exact contents of the version you choose.
