Simply put, frizzy hair is the sensation that your hair has a mind of its own. It feels dry and poofy, and might fray outward in all kinds of directions, instead of laying flat and smooth. <\/p>
It\u2019s important to know what is happening on a microscopic level, though, because that\u2019s the key to getting ahead of frizz in the first place. Here is how Bachowski explains it: \u201cThere are four types of bonding interactions that occur in hair proteins. One of them (and the most important to this topic) is hydrogen bonds. Hydrogen bonds are typically weak, which means that they can change or break easily. When you style your hair with heat and then you walk outside on a humid summer day and your hair loses shape and frizzes up, that\u2019s due to the hydrogen bonds in your hair breaking. Basically any introduction of water will break the bonds and force your hair to go back to its original shape.\u201d <\/p>
Hydrogen bonds are what\u2019s responsible for any shape your hair takes\u2014whether you\u2019re straightening it, applying a styler, or if it\u2019s pressed down onto your head by a hat. In all of these situations, the hydrogen bonds are at work. If you wet your hair and reset it, the bonds are broken but then reform as they dry. So, again, significant moisture (or even a lack thereof) in the air can compromise these bonds. If there\u2019s a lack of moisture in the air, then the hydrogen in your hair will dissipate into the air to try and create a balance. (The result: Unwanted frizz!) If there is too much<\/i> moisture in the air and it\u2019s quite humid, then that moisture will break down the hydrogen bonds in your hair, almost as if you had wetted it and let it dry naturally. <\/p>
