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.
Wait 12 hours, if possible, after the rain has stopped before mowing the lawn. Avoid mowing in heavy rainfall, as it is unsafe. Take your lawn mower to a professional for blade sharpening and adjustment if it has multiple blades. George Doyle/Stockbyte/Getty Images.
