What's good for the goose, may not be good for the gander.
Meaning, what works for her, may not work for me. I fully dry my hair, towel then some air drying, then 5 mins. blow drying THEN I brush my hair. It is always shiny, silky, smooth & sot, because of how I care for my hair.
Going to bed with wet hair doesn't damage the hair, but it produces greasier hair. I know that's what happens to me, me if I don't.
When my hair was damaged due to dyeing & perming, I finger comb my wet hair, gel it or blow dry & set them in plastic curlers. This produces silkier, softer, shinier, & smoother hair, by taming the curls. Finger comb or brush when styling.
I've used Suave before, good product for damaged, permed hair. It makes my hair greasy now, on the 2nd day, so I don't use it anymore, I took it back.
