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.
There are a few things to think about to help your grass get off to a good start: 1  A healthy lawn needs good soil. 2  Don't apply a weed preventer (liquid or granular) or use weed and feed fertilizer when planning to sow grass. You can control weeds only after you have mowed new grass seedlings at least four times. Any weed controls applied when you sow seed will prevent germination or kill immature seedlings.
