When I asked this while ago noone answered. I had to google it. Since I still don't "get it" I can't really help. Sorry.

In chemistry, the dew point is the temperature at water vapor in the air will condense and form liquid water (i.e. dew).

I have no idea what that has to do with hair. Whoever is using that term may mean something completely different.

Dew point is the temperature to which the air must be cooled in order to condense out and form dew. Because of this, the dew point will never exceed the air temperature.

The dew point helps indicate how much moisture is in the air...the higher the dew point, the more moisture there is. So...

high dew point, high temp.= hot and muggy
low dew point, high temp.= hot and dry
low dew point, low temp. = cold and dry


HTH!

You can check weather.com and see the dew point for your area. A dew point of 60 F means that it will start to feel humid. Anything over 65 F feels really sticky and quite uncomfortable. 40-60 F is typically the "ideal" for most curlies. Anything under 30 F tends to be quite drying.

Dew points under 30 F and over 60 F are considered extremes in opposite directions. The general rule is that when dew point is within one of these ranges, curlies should start using anti-humectants and heavier conditioners/oils. When the air is very dry, it tends to want to suck all of the moisture from our hair. Conversely, when there is a massive amount of moisture in the air, our hair tends to want to "reach out" and grab it, leading to frizz. Heavier products usually help combat this.

Humectants are recommended for the "ideal" dew point range, along with a good amount of moisture. Humectants draw moisture from the air into the hair, but because the amount of moisture in the air isn't excessive, they provide a good balance so that the hair doesn't frizz.

Hmmm. Maybe the dews are high in my area today. I noticed that each time I looked in the mirror my hair was bigger than the time before. Wearing 3rd day body shop conditioner and aloe Vera gel. Don't know if they're humectants, I didn't check. Thanks so much for your help!!! :-)

Not sure about the Body Shop, and people are still on the fence about aloe vera gel, but I'm almost certain that it's a humectant.

No problem!
