Forget to wash your hair for like a week and a half (just really let it get dirty)
Have a completely free Saturday to do your hair, have no plans, and all the free time, so that you can wash your hair.
Lay around all day and watch Youtube videos about natural haircare until you have successfully wasted 3 hours (at least).
Post on your insta story about how you need to wash your hair
Go back to watching Youtube videos
Finally decide to wash your hair at 3 in the afternoon, only to be thwarted by family doing laundry (since the washer and dryer are in the bathroom)
Repeat steps 3 through 5 until it’s 6 o’clock
Wash your hair (this step is optional)
