Perms and hair color. You can color hair that has been permed, but try to use a semi-permanent or 'no-ammonia' color instead of a normal permanent color (which uses ammonia and 20 volume peroxide). Have your hair permed first.
Mowing grass works best when the grass is dry, as grass tends to bend over from the weight of the rain, making it difficult to get a straight cut. It also clumps inside your mower cavity and on your lawn, which can lead to dead grass underneath the clumps if not raked promptly.
Soil will compact worse when it's wet which is one of the reasons you shouldn't mow your lawn when the soil is very moist. Different varieties of grass will also be a factor. I noticed the fine bladed grass commonly used in shady mixes retain the swirl direction more.
