Why hair gets frizzy in humidity




















Try alternative methods instead, for example: smoothing treatments that can last for 3 months or use heatless rollers. If you still find yourself reaching for your straightener, then I recommend investing in a good one that can protect your hair. These products apply a protective shield around the hair strands to protect them from heat and humidity. Over a long period of time, they also prevent your strands from succumbing to permanent heat damage.

Prevention is better than cure. Signs of hair damage are pretty obvious. Your hair will stop responding to conditioning and moisturizing treatments. If you suspect you have hair damage, I suggest you consult a hairstylist and find the right products that can nurture and restore your hair. An instant defrizzer adds smoothness, softness, and shine to your hair by replenishing natural oils. Packed with moisture-infusing ingredients like emollients and cationic conditioning agents, these sprays can tame frizz and unruly hair in minutes.

They are essentially anti frizz dry conditioning sprays that infuse natural oils-based moisture, seal the hair cuticles, and tame those fuzzy troubled spots without leaving any heavy residues. Just spritz it on dry hair in a sweeping motion and smooth it over with a brush or comb, and voila. An anti-frizz balm is an excellent styling product that helps you add hold and definition to your hair while reducing frizz and flyaways.

Scully on June 3, What is frizz? What causes frizz? What happens when hair frizzes? What causes hair to frizz? How to handle frizzy hair. Products to try. The bottom line. Because humid air has much higher numbers of water molecules than dry air, a given strand of hair can form much higher numbers of hydrogen bonds on a humid day.

When many such bonds are formed between the keratin proteins in a strand of hair, it causes the hair to fold back on itself at the molecular level at a greater rate. On the macro level, this means that naturally curly hair as a whole becomes curlier or frizzier due to humidity.

As an analogy, imagine the metal coil of a spring. The greater the humidity, the shorter the hair in the hygrometer becomes. Straight hair will become wavy, wavy hair will become curly and curly hair will become curlier. And, often, it will become downright frizzy to boot [source: Stromberg ]. So why does humidity make hair frizzy? When hydrogen bonds form between the proteins and water molecules in your hair, it will become curly and, potentially, frizzy.

A cross-section of an individual hair reveals many layers. For our purposes, we'll focus on the middle layer of the hair, which comprises coiled bundles of keratin proteins.

These bundles are held together by chemical bonds, created either by neighboring sulfur atoms or hydrogen atoms. The permanent bonds of sulfur atoms aren't affected by humidity; they help give hair its strength. The hydrogen atom bonds give hair its temporary shape. Every 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 again [source: Doherty and Shore ].
