Why Does Humidity Make My Hair Frizz
Just waves your luck. Ten minutes after leaving your blowout appointment, the weather takes a turn. Bright and sunny just minutes earlier, the skies have taken on a grayish hue, and the air is heavy with humidity. Your hair, which was all bounce and shine, is beginning to wilt. Before long, the next awful stage will set in: frizz. Blame your genes, hair products or unhealthy luck, but frizzy hair is the bane of your locks’ existence.
When the air is humid, excessive levels of hydrogen are current. (Remember, water is 2 elements hydrogen, one part oxygen.) And your hair is the primary to comprehend it, a veritable canary within the coal mine that may sense the unseen dampening forces creeping in throughout.
Turns out, the chemical make-up of human hair is extremely sensitive to airborne hydrogen. So sensitive, in actual fact, that some gadgets used to measure humidity — known as hygrometers — rely on hair for their readings. The better the humidity, the shorter the hair in the hygrometer becomes. Straight hair will develop into wavy, wavy hair will change into curly and curly hair will become curlier. And, typically, it’s going to turn out to be downright frizzy in addition [supply: Stromberg].
So why does humidity make hair frizzy When hydrogen bonds form between the proteins and water molecules in your hair, it can become curly and, doubtlessly, frizzy.
A cross-part of an individual hair reveals many layers. For our purposes, we’ll focus on the center layer of the hair, which contains coiled bundles of keratin proteins. These bundles are held collectively by chemical bonds, created both by neighboring sulfur atoms or hydrogen atoms.
The permanent bonds of sulfur atoms aren’t affected by humidity; they assist give hair its power. The hydrogen atom bonds give hair its short-term shape. Each time wet hair dries, the hydrogen atoms reform their bonds with hydrogen atoms on neighboring strands of keratin protein, and these bonds hold until the hair is wet once more [source: Doherty and Shore]. Hydrogen bonds are accountable for the bedhead you wake up with after falling asleep with wet hair.
Because hair is porous, it absorbs moisture when there is humidity in the air. Hair that is overly dry from chemically primarily based hair therapies is especially vulnerable. (Holding hair well moisturized can assist you avoid frizz.) When hair absorbs moisture, a single strand of it kinds significantly more hydrogen bonds between the keratin strands it incorporates. The hair primarily doubles back in on itself at a molecular degree, absorbing water, forming bonds and swelling until it disrupts the cuticle, which is the sleek, outermost layer of the hair. Enlarge this occurrence by an entire head of hair and the result is frizz [sources: Stromberg, Ray].
