There are days when, no matter how much we comb our hair, it seems impossible to keep it under control. We head out with a neatly styled look and, after a few minutes exposed to humidity, frizz, volume, and that fluffy appearance that completely alters the overall look.
Ambient humidity can especially affect dry, damaged, or highly porous hair, since the hair fiber can absorb moisture from the environment and alter its shape. But there are also some everyday habits that can make the hair even more vulnerable.
Therefore, if on humid days you feel your hair puffing up more than usual, it might not be solely the weather.
7 mistakes that cause it to swell and have more frizz
1. Going out of the house with the hair still damp
One of the most common mistakes is finishing a shower, drying the hair quickly with a towel, and leaving home while it’s still damp.
Wet hair is more vulnerable and, when it meets a humid environment, can absorb even more water. The ideal is to leave it completely dry before going out, especially when the weather is very humid.
2. Rubbing the hair with the towel
After washing, many times we wrap the hair in a towel and rub it to remove excess water. However, this gesture can create friction and promote frizz.
Instead of rubbing, it is preferable to gently press the hair to remove the water. You can also use a microfiber towel or a soft cotton T-shirt.
3. Overusing heat styling tools
Hairdryers, straighteners, and curling waves can become great allies for styling, but using them excessively can dry out the fiber and make it more vulnerable.
On humid days, a heat protectant is essential if you plan to use heat tools. Also, it’s advisable to avoid excessively high temperatures and not to repeatedly go over the same area.
4. Not hydrating the hair
A dehydrated strand can show more frizz and feel rougher. Therefore, during humidity periods you should not skip hydration thinking it will add volume.
Conditioner after every wash and a moisturizing mask once or twice a week, depending on your hair’s needs, can help keep the fiber softer and more manageable.
5. Brushing it too much
Brushing repeatedly to try to settle the flyaway hairs can end up having the opposite effect.
Excess brushing creates friction and can increase frizz, especially in wavy or curly hair. In these cases, it’s better to detangle gently and use a finishing product that helps control the texture.
6. Using products that aren’t suitable for your hair type
Not all hair types need the same products. A formula that’s too light may not be enough to control dry or porous hair, while something too heavy can make fine hair look greasy.
For humid days, anti-frizz products, serums, or styling creams can help form a barrier and keep the hair more controllable. The key is to choose them according to each mane’s type and needs.
7. Going to bed with wet hair
Another habit to avoid is going to sleep with wet hair. Besides increasing friction against the pillow, it can leave the fiber more prone to frizz and make styling the next day harder.
The ideal is to go to bed with the hair completely dry. If you’re prone to frizz, a satin pillowcase can help reduce nighttime friction.
The key to controlling frizz on humid days
Not all humidity can be prevented from changing the hair, but it is possible to prepare the fiber so it is less vulnerable. A routine that includes hydration, careful drying, thermal protection, and suitable products can make a difference.
And there’s one important point: having a little frizz does not mean the hair is “bad.” Humidity is part of the environment, and every hair type responds in its own way. The goal should not be to completely erase its natural texture, but to keep it cared for, hydrated, and healthy.
