  • How can I improve my hair conditioner for humid conditions?

    Posted by kannes on February 28, 2023 at 2:05 pm


    I’ve been working on a solid hair conditioner bar this winter and I finally got the formula where I wanted it to be. My hair had been LOVING it and was beautifully shiny, bouncy, and silky. Then it got humid this week for the first time since I’ve started formulating and hair is now a little frizzy/poofy and not very silky when outdoors…the texture feels a little bit rough now.

    I’ve got silicones in the formula so I thought that would’ve helped prevent moisture from getting in the hair to cause this frizz. Do y’all have any advice on what I can do to improve this formula for humid conditions? Any tips much appreciated. Thank you!

    This is a tough one here. You were smart to include the silicones and that should fend off any humidity affects. I can only point to that cassia polyquat. That is likely hygroscopic in solid state. On the other hand, maybe all the cationic salts here are hygroscopic in solid state? Would adding more dimethicone help?

    Two theories from my side: 1) the change of weather made you switch the temperature of your shower (since you’re using a bar, the hotter the environment, the more deposition you’ll have as long as you’re a bit above the bar’s melting point), 2) before it got humid, you didn’t require any special benefit from your bar (conditioning bars don’t perform as good as regular emulsions), but humidity makes hair a bit messy, and that’s when you notice a conditioning bar is not good enough.
