short loose strands

i posted here a few months ago and since have followed up with all the advice i was given. my hair is noticeably healthier now, i cut it and got a keratin treatment, and a few months later got a black glaze.

the stylist at my salon recommended keratin shampoo and conditioner after i got the treatment, so i was using it for a month or so until i noticed dandruff, and stopped using the shampoo but not the conditioner.

all good now, but i’ve noticed my hair almost like frizzy towards the top/middle. these pictures are my freshly washed hair with a smoothing cream in, and these strands are still coming through. i feel like it’s worse in person as well. my hair is thin, and a couple years ago i got short layers, so maybe it’s that? my hair is pretty wavy as well. sorry if this is a silly thing to be worried over, im just curious why this is happening.
