Hair products like head lice treatment

[MotherofaToad]

If recently had head lice (I'm a teacher) and I love how the nitwits treatment leaves my hair. It's so soft, sleek and shiny.
What hair care products would leave my hair like this?
I don't want to have to keep on getting lice so that I can use nitwits again!

funnily enough we used one before; a more oily treatment and it killed my frizz dead until next wash, I’ve been trying to recall which it was. I might check out nitwits myself lol

The key ingredient is dimethicone so you need something with that in it. Gliss night elixir is what you're after.
