Have you ever wondered why your hair could love your products in mild weather, but in hot climates it gets puffy and dry in cold temperatures? This is because of moisturising agents found in your products called Humectants. In the right environment, Humectants moisturise dry and damaged hair. These ingredients promote moisture retention by attracting water from the air to your hair.
However, the effectiveness of them working depends on the humidity of where you are.
HIGH HUMIDITY & MOISTURE
If there’s a lot of weather in the air when it’s hot and humid, humectants work overtime and absorb TOO much moisture. As a result, your amazing Twist out will quickly turn damp, puffy and frizzy.
Those with high porosity hair will experience this worst.
LOW HUMIDITY & MOISTURE
During cold dry winters, humectants will draw moisture away from your hair into the air. This is because moisture will move from high moisturised areas to low moisturised areas.
Unfortunately this all leads to your hair feeling dry.
Regarding when the best time is all comes down to the Dew Point. This is when water vapour turns back into liquid. It is not about the climate!
Dew points between 35 degrees Fahrenheit – 50 degrees Fahrenheit (approximately 1-10 degrees Celcius) is optimal. If the level is 65 degrees F (18 degrees C) or more, use products with anti-humectants to seal the hair shaft.
Make sure your hair is properly hydrated, moisturised and sealed. By doing this, your hair won’t lose much moisturise in dry weather and stop it from absorbing too much in humid conditions.
In addition, you can improve your hair if it is high porosity. Use anti-humectants if this applies to you.
LIST OF HUMECTANTS
Here is a list of some common Humectants to be aware of:
- Silk Keratin
- Aloe Vera Gel
- Agave Nectar
- Butylene Glycol
- Sodium PCA
On the flip side here is a list of some Anti-Humectants:
- Avocado Oil
- Shea Butter
- Coconut Oil
- Olive Oil
Only use in high dew points and excess humidity. Also make sure you stay away from these during cold dry temperatures and low dew points.
A final tip is if you’re using a product high in humectants, use a moisturiser that is high in emollients and oils. For example, you gel has Glycerin high up in its ingredients list. In cold weather, use a moisturising hair butter first.
