Glycerin and honey are humectants.
What are humectants?
A humectant is a substance that helps a product retain water. Humectants attract moisture and humidity. They allow whatever moisture is in the air to be absorbed into whatever they are applied to.
I tried using my bottle of glycerin as a sealant, but it just makes my hair frizzy, which should have been expected, as it attracts moisture/humidity.
Today I decided to use it as a pre-poo. And I say pre-poo as in not just before shampooing. I Iike to pre-poo before I co-wash sometimes when I have time.
Why glycerin as a pre-poo?
Well if you think about it, humectants attract moisture/humidity/steam right? So if you apply it to your hair before you wash/co-wash, the steam from the shower will allow your conditioner and the water to fully penetrate your strands when rinsing, which I imagine will give your hair a silkier feel.
I Googled glycerin pre-poo before writing this post and minimal results came up. Using myself as a guinea pig, we’ll see if this works. It should. It only makes sense.
Update, plus a pic after I wash it out.
Note: Honey, as I said is also a humectant and can be used as a substitute for glycerin, but may be more difficult to apply to dry hair as a pre-poo.
Warnig: Overtime honey and glycerin will lighten your hair, or affect its color, so this is an fyi.
