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.
A height of two inches is fine when grasses are rapidly growing, but the height should be raised as growth slows, stress increases, and when the lawn is in shade. Lawns should be mowed according to the rate of grass growth; remember not to remove more than one-third of the grass leaf in any one cutting. Mowing as the lawn needs it is essential. In the spring, this will likely mean more than once a week. It is never advisable to mow when the grass is wet. Another issue related to mowing is whether clippings should be collected.
