Is glycerine good for dandruff?

Unless you want your head to feel like a sticky sweet box, don't put pure glycerine directly! If you must use it, dilute it well, or you'll have dust sticking to your hair all day.

I can only speak from my experience, but glycerine made my scalp too greasy and actually worsened my dandruff. I found that a simple anti-dandruff shampoo containing ketoconazole worked much better for me.

My teenager had very dry scalp and dandruff. We tried applying a little glycerine diluted with water before hair wash, and it did reduce the dryness. But make sure to wash it off thoroughly so it doesn't attract dust.

I love trying DIY scalp remedies while waiting for my food deliveries! Glycerine mixed with a few drops of lemon juice worked nicely to soothe my dry, itchy winter scalp.
