It's a mixture of two things – humid or hot weather, and how moisturised your hair is to start with. The main cause of frizz is a lack of moisture in your hair. This causes your hair to seek out and absorb moisture from the air, causing frizz - which also explains why humidity can make frizz even worse.
Even for healthy hair, high humidity environments can lead to frizz when your hair absorbs excess moisture. When your hair is dry, frizz can happen when it absorbs moisture from the environment. Over-styling damaging the hair cuticle and causing frizz. Heat damage and styling is another common culprit of frizzy hair.
Why does hair get dry as we age? As we get older, our hair texture changes dramatically. Hair will slowly become drier, coarser, and thinner over the years. The truth is that as we grow older, the oils that our scalp relies on for nourishment decrease, resulting in drier, frizzier hair.
If you notice your hair is frizzy after you apply conditioner, this may be because you haven't applied it on soaking wet hair. Your hair may also feel frizzy due to a lack of moisture, so you want to apply a deep conditioning masque that will help to prevent dryness.
Krysta explains, “Conditioners can also make your hair frizzy if you don't use the right type or amount for your particular hair type.
Deficiencies in any of the following vitamins and minerals could manifest as conditions including generalized hair loss, frizziness or brittle hair: Biotin (vitamin B7): Biotin activates enzymes that break down the carbohydrates, fat and protein necessary for hair production and reducing frizz.
Your Water Is Too Hot
Hot water melts away your natural hair oils, leaving it dry, brittle, and frizzy. Excess heat also lifts your hair cuticles, the outermost layer. When that happens, the cells separate and the cuticle layer can't seal itself—another cause of frizzy hair.
During menopause, estrogen and progesterone levels drop and wreak havoc with our hair. Thick, smooth, shiny locks are suddenly thin, dry, and frizzy.
The primary cause of straw hairs is a lack of moisture and proper conditioning, as the hair fibers become hardened and stiff. To restore healthy hair, it is essential to maintain adequate moisture levels at all times. This can be done by using mild cleansing products and rich moisturizing formulations.
“A reduction in estrogen results in reduced sebum (oil) production, which normally lubricates the scalp. The result is dry skin and a flaky scalp,” says Kunin. And, since that hydrating scalp oil isn't there to work itself down your strands, hair is also drier, as well as duller, more brittle, and breakage-prone.
“What tends to happen, particularly in humid weather, is that the cuticles don't seal properly, which leads to frizz.
Though stress affects everyone differently, one thing seems to be consistent across the masses: stress wreaks havoc on hair. When stress takes over, your body is prone to imbalances in hormones and bacteria, which can cause dry skin or rashes. A dry scalp can result in flakiness and dull-looking hair.
Moisture overload occurs when there is too much moisture and too little protein. This is the second kind of imbalance your hair can experience. Moisture overload tends to affect those who have high hair porosity, causing it to look limp, stringy, and even greasy.
Limp, gummy, or mushy hair — If your hair feels limp, gummy, or mushy when wet, then that is a strong indication that your hair is over-moisturized.
Straw-like strands may also be the result of daily heat styling, overuse of hair products, and even changes to your diet. You can resolve these issues head-on by making small changes to your routine.
Fried hair is the result of using harsh chemicals, such as those found in bleach and hair coloring treatments, or excessive heat to style your hair. So, if you're suffering the consequences of overbleaching or overusing heat, don't worry; there are several ways to repair fried hair.
A lack of moisture is not uncommon due to hormone issues, especially for people going through menopause. If you have natural waves or curly hair then you'll know that dryness can already be an issue and frizzy hair can already be a problem! The key is to restore your hair's moisture.
Use a gentle, moisturising shampoo and conditioner when you wash your hair. Choose products that are made specifically for dry or damaged hair that will increase its elasticity. You can also incorporate a weekly hair mask (e.g. egg and olive oil) or hot oil treatments into your routine to further nourish your hair.
