The effects of humidity on hair can range from frizzy to flat and, as humidity doesn’t play favorites, no one is immune. People with all hair types are forced to deal with impossible to manage hair on those days when the humidity spikes.
It happens when it is sticky outside because the molecules in the air have been altered. What that means to hair, which is porous, is that while dry air can dry out your hair, hair absorbs moisture when it is humid – causing hair to “grow” and create puffy ends…and definitely not in a good way, if there is one.
Hair strands absorbing varying amounts of moisture usually result in bending, twisting and/or frizzing hair. Although all hair types are negatively affected by humidity, each is affected differently; and because even the proteins on the same head of hair can vary, each of the hair strands on one person can be affected by humidity in different ways too.
Typically, people with curly hair deal with excess curling and frizz. Thin hair may become limp or flat at the top and thicker toward the end of the hair strand – also a very undesired effect. Very dry damaged hair is the worst, because it tends to absorb even more moisture during humid days – amplifying all of those unwelcome effects.
Although humidity remains a challenge for all of us, the solution is product. You can help prevent the negative effects of humidity by keeping your hair suitably conditioned and full of nutrients. A vitamin-rich diet will help. Volumizing products for flat hair and serums and smothers for curlier, thicker hair – added when hair is damp – can help as well.
