Humidity can have a dramatic impact on both your skin and hair, and knowing how to manage these effects is key to looking and feeling your best-especially as we head into warmer, more humid months.
How Humidity Affects Your Skin
- Increased Hydration (Sometimes Too Much): High humidity allows your skin’s outer layer (the stratum corneum) to absorb more moisture from the air, which can improve hydration and help your skin barrier function better. This can make skin look plumper and younger.
- Clogged Pores and Breakouts: On the flip side, humidity opens pores and increases sweating, which, when combined with dirt, oil, and makeup, can clog pores and trigger breakouts, blackheads, and even fungal infections or eczema flare-ups.
- Sensitivity and Irritation: Those with sensitive skin or conditions like eczema and psoriasis may notice more flare-ups in humid weather due to increased sweat and trapped bacteria (1).
What to Do:
- Cleanse skin twice daily to remove sweat and buildup.
- Use lightweight, non-comedogenic moisturizers.
- Exfoliate gently 1–2 times a week to prevent clogged pores.
- Apply sunscreen daily, as UV exposure can worsen humidity-related skin issues.
How Humidity Affects Your Hair
- Frizz and Curl Changes: Humidity is notorious for making hair frizzy. That’s because hair is porous and absorbs moisture from the air, causing the hair shaft to swell and disrupt the smooth cuticle layer. This leads to frizz, especially in dry or chemically treated hair. Straight hair may become wavy, and wavy hair may get curlier or more unruly (2).
- Swelling and Weakness: Excess moisture can cause hair to swell, making it more prone to breakage and less able to hold styles.
- Hydration (With a Downside): While humidity can provide some natural hydration, too much can make hair unruly and difficult to manage.
What to Do:
- Use anti-frizz and humidity-resistant hair products, like serums or creams.
- Deep condition regularly to keep hair hydrated and less likely to absorb excess moisture from the air.
- Apply a heat protectant if you use styling tools, as it helps seal the hair shaft and block out humidity.
- Try protective hairstyles (like braids or buns) to minimize exposure to the humid environment.
- Avoid over-washing, which can strip natural oils and make hair more vulnerable to frizz.
FAQs
Q: Is humidity good or bad for my skin?
A: Humidity can help keep skin hydrated but may also increase the risk of breakouts, clogged pores, and irritation if not managed properly.
Q: Why does my hair get frizzy in humidity?
A: Hair absorbs moisture from humid air, causing the shaft to swell and the cuticle to lift, resulting in frizz and loss of smoothness.
Q: How can I prevent breakouts and frizz in humid weather?
A: For skin, cleanse regularly and use lightweight products. For hair, deep condition, use anti-frizz products, and try protective styles.
