Personal hygiene is critical to feeling well and having good days. Shower in the mornings and bath in the evenings. Take care of hair and makeup and always use deodorant and a little perfume.
Whatever is a step more than you do now. If that means brushing your teeth, combing your hair, taking a shower/bath or a full face of makeup thats up to you!
Grooming yourself includes brushing your hair, trimming nails, putting on lotion/deodorant/perfume, just the little hygienic things you do to improve your overall look!
