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.
Damage to new lawns often occurs during the early stage of seed establishment. Knowing when to mow and water, as well as the correct cutting procedures, produces strong, healthy growth in newly planted lawns. Homeowners may have to wait up to two months before mowing the lawn after seeding.
