Why Does Humidity Make My Hair Frizz
Just waves your luck. Ten minutes after leaving your blowout appointment, the weather takes a turn. Shiny and sunny simply 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 following awful stage will set in: frizz. Blame your genes, hair products or dangerous luck, but frizzy hair is the bane of your locks’ existence.
When the air is humid, excessive ranges of hydrogen are current. (Remember, water is 2 components hydrogen, one part oxygen.) And your hair is the first to comprehend it, a veritable canary in the coal mine that can sense how to keep your hair from getting matted while sleeping the unseen dampening forces creeping in all around.
Seems, the chemical make-up of human hair is extraordinarily delicate to airborne hydrogen. So sensitive, in truth, 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 turns into. Straight hair will develop into wavy, wavy hair will grow to be curly and curly hair will grow to be curlier. And, often, it is going to develop into downright frizzy besides [supply: Stromberg].
So why does humidity make hair frizzy When hydrogen bonds kind between the proteins and water molecules in your hair, it should develop into curly and, doubtlessly, frizzy.
A cross-section of an individual hair reveals many layers. For our purposes, we’ll concentrate 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 help give hair its energy. The hydrogen atom bonds give hair its momentary form. Each time wet hair dries, the hydrogen atoms reform their bonds with hydrogen atoms on neighboring strands of keratin protein, and these bonds hold till the hair is wet once more [supply: 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’s humidity within the air. Hair that’s overly dry from chemically based hair therapies is especially susceptible. (Conserving hair effectively moisturized can assist you keep away from frizz.) When hair absorbs moisture, a single strand of it varieties significantly more hydrogen bonds between the keratin strands it accommodates. The hair essentially doubles back in on itself at a molecular level, absorbing water, forming bonds and swelling until it disrupts the cuticle, which is the smooth, outermost layer of the hair. Magnify this prevalence by an entire head of hair and the result is frizz [sources: Stromberg, Ray].
