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.
Don't water again for 48 hours, as this might wash the weed and feed off the weeds. Wait three to five days after applying weed and feed to mow. Water at least once before mowing to help the fertilizer portion of the weed and feed penetrate into the soil. Allow the grass to dry completely before mowing. Mow the lawn normally, but avoid using a mower with a bag attachment.
