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.
Tip 2: Mow a Dry Lawn. Wait for your lawn to dry before mowing. Cutting wet grass can result in an uneven cut. Wet clippings can clog your mower, too, dumping clumps of grass on your lawn which can smother the grass and result in brown spots. Mow in a different direction every time you mow.
