Humidity Confusion

Loveliam

Over time I have heard and read two different messages about hair and higher dew points/ humidity.

1. Frizz comes from lack of moisture. Hydrate hair very well in humid weather.

2. When dew and humidity are higher, you need less moisture and more control.

So is this a case of what you need may differ based on your specific hair?

First one has to understand that dew points depend on humidity to be calculated, but humidity is not the same thing as a dew point. That confused me for a long time. Frizz from a lack of moisture is normally when dew points are low, but humidity may or may not be low.

High dew point and/or high humidity mean that there is more moisture in the air at certain temps so you may need more anti-humectants or sealers whether they be oil, gel, silicones, etc. I couldn't use honey this summer- it made my hair really hard. I think that with increases in temperature and the same humidity, my dew points went really high or really low. Either way, my end result was that my beloved curl cream with honey made my hair so hard I couldn't scrunch out the crunch. I really like this website: Dew Point Calculator to calculate dew point and the dew point explanation in the main naturally curly site. This article The 411 On Dew Points & Humectants wasn't it, but I really liked it.

Is this the one you meant? It's by Tonya McKay, the Curl Chemist. Humidity, Humectants and the Dew Point

Happy to help. I keep a folder of hair bookmarks in my browser so I don't have to remember everything.
