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.
The Halts (or Turf Builder with Halts) should be watered after application or apply before rain. The Turf Builder Weed & Feed should be applied to a moist lawn when rain is not expected for 24 hours. A good time to apply is to a lawn moist from dew first thing in the morning. Your lawn can be watered after 24 hours.
