This often involves split ends as well, which makes the inherent frizziness seem worse. Frizzy hair can occur in all hair types, but most of all in curly, fine hair. It can be maddening. Frizzy is defined as tight, wispy curls, but in a broader sense it also refers to hair that has gone out of shape, sticking up in wisps and losing it’s smoothness. Frizziness is also controlled by humidity and static electricity -and, furthermore, amongst the curlier hairs there are straighter ones. Hair is not uniform throughout, and together with variations in shape, there are variations in lengths. Making it even more maddening are the changes that occur during the day depending on where you are and the relative humidity. You can be at home, in an office, go out on an errand, go to a shop, take a walk, go into and out of air conditioning or central heating – all of which result in humidity changes and the degree of frizz your hair will have.
Hair expands and stretches and changes its protein bonds temporarily when wet or damp. During drying, the hair’s shape is defined with whatever way you style it. You may dry it straight or wavy and it will keep this shape until it is wet or is being affected by humidity, when the hair will gradually revert into its natural configuration again. And this can change numerous times throughout the day. The way to protect from the ‘frizzies’ is to dry and style your hair with products that discourage moisture absorption into the hair shaft. Originally these products, in which the most active ingredients would be silicons, were almost waterproof and were impossible to remove without multiple washes. Newer versions don’t (or should not) do this. They are moisture resistant, lighter in texture, are effective anti-frizz products and wash out more easily. You need to choose carefully because some still leave the hair feeling greasy, coated, heavy, dull and even dry. Another point to remember is that little is best. Too much should be avoided because a lot of silicone used on wet hair to style it with the blow-dryer against frizzing up, can result in what I call ‘silicone burn’ – an unpleasant brittleness and dullness that is almost as maddening as the frizz.
