In this post, we’ll explore why some hair types are prone to summer humidity and share the best shampoo and conditioner for frizzy hair in humidity.
Key points:
- High humidity can restructure hair, leaving it prone to frizz
- Dry, damaged hair is most at risk of frizz
- We recommend Green People Moisturising Shampoo and Moisturising Conditioner for humidity frizz control
- You can also help reduce frizz by reducing heat exposure from the sun and styling tools, sleeping on a silk pillow and drinking plenty of water.
Why does humidity make my hair frizzy?
Does your hair get frizzy and wild in hot, humid weather? The UK has a higher level of humidity than continental Europe, which can create the perfect conditions for dry, frizzy hair.
How? Hair loses its structure as it absorbs the warm moisture in the air, going from sleek and smooth to fluffy and poofy.[i]
All hair types can feel frizzy in summer, but dry or damaged hair prone to split ends, flyaways and breakages are more likely to notice frizzy hair during periods of humidity.
Wavy and curly hair can also be more prone to humidity frizz because as the curls grow, they force a layer of hair outwards, leading to dehydration.
But you don’t have to worry; making a few hair care swaps can tame frizz and restore a sleek, smooth summer style.

How else can I stop my hair getting frizzy in humid weather?
Dry, damaged hair craves smoothing and strengthening moisture, and there are several ways to boost your hair’s resilience to frizz-inducing humidity before summer.
Manage sun and heat exposure
Stay out of the heat during the hottest hours, usually 11 a.m. to 3 p.m. and protect your hair with a stylish sun hat or silky/satin headscarf when you’re out and about.
And it’s not the sun that can steal your sleekness. Steaming shower water and heated styling tools can damage hair, leading to breakages and dehydration. For a smoother, frizz-free style, give your hair dryer the summer off and swap to heatless styling tools instead.
Avoid cheap, drying shampoo ingredients
Ditch the drying ingredients in your hair care products and opt for humectant-rich hair repair actives instead.
Ethanol alcohol and harsh foaming agents can strip away at your skin and hair follicles, but they can easily be avoided.
Our natural and organic shampoos do not use drying alcohol or harsh foaming agents. Instead, they are enriched with strengthening plant proteins, a hydrating core of scalp-soothing Aloe Vera, and gently cleansing Coconut foaming agents.
Control with conditioner
Conditioners do much more than detangle; they’re key to strengthening hair to fight off frizz! Their hydrating actives are deeply nourishing and help to nourish and repair hair, making it less prone to dryness and breakages.
To keep frizzy hair soft, smooth, and hydrated in summer humidity, condition it after every wash and apply a conditioning mask at least once a week.
Let loose
Tight plaits and ponytails can strain fragile follicles, leading to split ends and breakages. Let your hair down, and if you tie it up, opt for a silk or satin hairband to reduce frizz risk.
Sleep on silk
Silk pillowcases are thought to control frizz by reducing friction. Silk heatless curlers can also be worn overnight and produce beautifully bouncy curls without needing heated styling tools.
Drink up!
Hydrate your hair from within by drinking 6-8 glasses of water daily. This is especially important when it's warm and sunny and will help your skin stay healthy, too.
