I’ve been doing hair oil and brushing pretty much every night and it works until I don’t. Our pediatrician suggested a little celsum blue on the scalp for 5 minutes and then rinsing. I haven’t tried it yet though because I remember I hated the smell of it when I was a kid lol, but just another suggestion
Baby oil every time baby takes a bath put some baby oil and a few days it’s gone … I used it for my first baby and works great 😊
