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.
When to Dethatch. For cool-season grasses, the best time to dethatch is late summer or early fall. That's when your grass is growing most vigorously. For warm-season grasses, dethatch in late spring or after the second mowing.Before dethatching, mow a little shorter than normal.n aerator pulls plugs out of your soil. This helps loosen compacted soil and allows air and water to reach the roots. Aerating is considered a better way to dethatch your lawn since it puts less stress on it.
