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.
Don't fertilize lawns in the spring for cool season grasses. Don't fertilize warm season grasses in the winter. Mow cool season grasses high in the spring and warm season grass high in both the winter and spring. In the summer, use a metal garden rake to pull out creeping stems of these weeds.
