If you shampoo every time you take a shower, well, you're shampooing too much. Short and simple. You don't want to dry out your hair! Those with fine, delicate hair can shampoo up to twice a week. Those with coarse and curly hair: bump it down to once. You'll save so much money on product!
The answer is probably yes. Staying in the shower for too long can irritate your skin, making it dry and itchy. Keep your showers down to at most once a day. And limit them to no more than eight minutes at a time. But don't scrub too quickly, otherwise you can slip and bump your head.
OK. You're getting a mani-pedi later today. You want to make sure your ankle hair isn't curling up in front of the girls at the salon. So you shave your gams. But you shouldn't. Why? Because that can increase the risk of infection. Not all salons are up to code, and your hair follicles are meant to catch germs before they enter the skin. So keep those bad boys long and strong to defend against invaders!
Your shower head could be your worst enemy. Those pores can harbor bacteria that spew onto your scalp and body when you're taking a shower. The high-flow shower heads are the worst. Consider a rain-type shower head, or just scrap the whole whatchamacallit and receive the full quantity of water right from the spout — unimpeded.
We all want to wear the crown. But are we going to get it greasy and oily? That's what will happen if we condition our hair above the crown line. We can prompt the production of unnecessary oils and greases. Rather, we should restrict our condition-usage to the roots first, and keep it at that. That way we don't shine up that tiara we know we should be wearing forever and always.
Speaking of shower injuries, oils are one thing you might want to avoid. They might feel great, smell nice, do all the good things to your naked bod. But they can also kill. Well, not directly, but they can make the floor and walls dangerously slippery. Swap that stuff out, and stay upright.
Lastly, and perhaps most importantly, don't kill people in the shower. It might look great in the movies, but in real life...it's illegal. It also creates a heaping mess that you probably don't want to have to deal with. So let them enjoy their oil-less, lukewarm wash down without imposition and interruption. Who knows...they might even ask you to join.
