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.
Repeat watering only when the surface of the soil begins to dry. In hot, dry conditions, you may need to water your grass again within four or five days. Allow the dry areas of grass to grow to at least 3 inches high and then mow. Leave the grass clippings on the lawn to help retain moisture. Avoid walking on your lawn during dry periods. The soil compaction caused by foot traffic can cause grass to dry out faster.
