You will need to wait at least 12 hours before having a shower after a henna design. It’s a good idea to coat the design in an oil such as coconut or olive oil or alternatively, use some cocoa butter to protect the design from the water. Avoid scrubbing or soaping the henna design when showering. This will help to keep the design on for longer.
The length of time henna will remain on your skin depends on the quality of the henna applied, where the design is located, your own skin’s regeneration rate and how well the henna design is cared for. A henna design may last anywhere between one to five weeks. Henna designs on the hands tend to last less time than elsewhere due to the constant use of your hands and hand-washing, and will usually last around one to two weeks. On other parts of the body, the design may last up to five weeks.
Wait at least 12 hours before washing a henna tattoo; even then, avoid scrubbing it or using any harsh detergents. It may also be useful to cover the henna design with olive or coconut oil or a plant butter such as cocoa or shea butter, to provide a waterproof cover that helps the design to last longer.

After the first 24 hours, yes - but only if the paste has been removed or fallen off. If you are showering, apply Vaseline to protect your henna. Try to avoid water as much as possible because it could cause the henna to fade faster.
No, it will not completely ruin the henna - as long as you don't harshly rub the area with soap or other cleaning products.
