Use got2b freeze spray and water from a shower won't affect it unless you get it on your mohawk directly from the faucet. Knox if you have a firehose commin' out of your ceiling!
My power was out for 2 months after a hurricane hit, and I kept it up the whole time.
Sleeping with it up can take some getting used to. Try taking benadryl or melatonin before going to bed to ensure you sleep.
i dont shower every day.... or every other day... im kind of a disgusting person.
and i sleep on my side... so if anything it just gets messed up a bit in the back, just add more hairspray.
mine is only up for the weekend. if its winter then no i prob dont need to shower and just wash my face and pits prob my junk to with a wet rag lol. (always have clean balls people)
but if its summer. pfft ill shower with the hawk up and use rag on face ,neck and side of the head. got2be freeze spray does hold it up pretty nice.
