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.
When to Water After Mowing. You can safely water your lawn after mowing whenever it needs moisture. However, you should prepare for this properly. Watering late in the afternoon or at night can cause fungal problems, because the grass doesn't have time to dry before nightfall.
