First, what is dew point? Dew point is the temperature at which air reaches 100% relative humidity, meaning it can no longer hold water vapor, and dew begins to form. It directly measures the amount of moisture in the air, which makes it a more reliable indicator of how humid it feels than relative humidity alone. For instance, a high dew point signals more moisture, making the air feel muggier, while a low dew point indicates drier air.
Now, how does dew point affect your curls? Depending on your hair type and preferences, the moisture in the air can either enhance or disrupt your style. Here’s how to navigate this invisible "styling product":
If You Love Humidity: Your hair likely thrives with humectants—ingredients like aloe or honey that attract water. In low dew point conditions, your hair might crave more moisture. To supplement, consider leaving in a bit of conditioner, using creams, or deep conditioning more frequently. This helps mimic the moisture your curls are missing from the air.
If Humidity is Your Hair’s Nemesis: High dew point conditions might leave your hair feeling frizzy or unmanageable. To combat this, steer clear of humectants during humid weather. Instead, opt for products that repel moisture, such as humectant-free gels like Ouidad Climate Control. These products help lock in your style and prevent frizz caused by moisture overload.
Personalizing Your Routine: Adapting your hair care routine to seasonal dew points can make a significant difference. For example, in Maine’s humid summers, I rinse out all conditioner, use gels or foams, and finish with a humectant-free product. In winter, I deep condition as needed, incorporate creams, and use light-hold humectant gels to maintain hydration.
By understanding how dew point influences your curls, you can create a routine that works harmoniously with your environment. Embracing this knowledge empowers you to support your hair with less effort, leading to happier, healthier curls year-round.
