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 new sod lawn should be mowed for the first time between 12-14 days. Turn off your water for 1 to 2 days to firm the soil to allow foot and mower traffic. After your first mowing water ONCE A DAY at 8 AM for the following week.
