Frizzy Hair Care: Top Treatments & How to Get Rid of Frizz

Last updated October 09, 2025

Understanding the root causes of frizzy hair is the first step to smoother, sleeker hair. We'll reveal the common culprits and share expert frizzy hair care tips for banishing the frizz for good.

What Causes Frizzy Hair?

Frizzy hair is primarily caused by a lack of moisture. Parched hair absorbs moisture from the atmosphere, causing the hair cuticle (the outermost layer of the hair shaft, composed of overlapping, scale-like cells) to swell and lift. Heat styling, harsh ingredients, chemical treatments, as well as certain hair care routines (e.g., over-washing, towel drying) can also damage the hair cuticle, making it more prone to frizz.

Humidity and Moisture Loss

Dry, porous and damaged hair coupled with high humidity levels cause frizzy hair because the hair cuticle lifts and swells as it absorbs moisture from the air, disrupting the hydrogen bonds that give hair its shape.

Heat Damage from Tools

While convenient, styling tools like flat irons and curling wands can damage hair over time. This is because the heat strips away your hair’s natural moisture and oils, contributing to frizz and breakage. Try to limit your use of these tools, and always protect your hair with a heat protectant spray.
Pro tip: turn the heat to the lowest possible setting.

Over-washing and Removing Natural Oils

Frequent shampooing, especially with harsh formulas, strips the hair of its natural oils, disrupts your hair's natural balance, and makes your hair more vulnerable to frizz. Try to reduce shampooing to 2-3 times a week, and switch to a hydrating shampoo and conditioner infused with oils and butters to help replenish that all-important moisture.

Split Ends and Unhealthy Hair Ends

Split and damaged ends create a rough hair texture leading to visible frizz. Regular trims (every 6-8 weeks) are essential for removing damage and preventing further breakage.

Use a Pre-Shampoo Treatment

Incorporating a pre-shampoo treatment, such as Garnier Fructis Hair Filler Pre-Shampoo Treatment, into your frizzy hair care routine helps protect hair during washing by reducing moisture loss (the main cause of frizz), and strengthening and repairing broken bonds. Apply evenly to wet hair, leave for 5 minutes, and rinse thoroughly.

Avoid Over-washing

Frequent shampooing strips natural oils and moisture, causing dryness and frizzy hair. As part of your frizzy hair care routine, reduce shampooing to 2-3 times a week, and always use a deeply moisturizing shampoo and conditioner.

Dry Hair Gently

Because water weakens the protein structure of hair, wet hair is more elastic and more susceptible to damage than dry hair. To minimize frizz and breakage always dry hair as gently as possible. Opt to blot your hair with a microfiber towel or an old t-shirt instead of rubbing hair with a towel. Alternatively, let it air dry — either partially or completely.

Use Heat Protectant Before Styling

Because you don’t want to lose any precious moisture during styling, always apply a heat protectant product to shield your hair from the damage caused by hot styling tools (flat irons, curling wands, hair dryers). Heat protectants work by creating a barrier on the hair shaft to minimize moisture loss, the main cause of frizzy hair.

Use Low-heat Styling

Hair loses moisture during styling because the heat causes the overlapping scales of the cuticle to lift, exposing the more vulnerable inner cortex. To prevent heat damage, always turn your styling tools to the lowest temperature setting. If you’re using a hair dryer, attach the diffuser as this distributes the heat more evenly.
Pro tip: air dry your hair when possible.

Finish with Leave-In Products and Overnight Protection

Leave-in products help hydrate and detangle, as well as controlling frizz. Consider layering leave-in conditioners infused with oils to seal in moisture for longer.
Pro tip: switch your cotton pillowcases for silk or satin ones to minimize frizzy hair, and consider using the overnight pineappling technique.

Apply Hair Masks and Deep Conditioners Regularly

Regularly using hair masks and deep conditioners helps restore hydration levels, as well as smoothing frizzy hair textures, and strengthening hair. Apply the frizzy hair treatment from the mid-lengths to the ends once or twice a week, and leave it to work its magic for 3-5 minutes.

Finish Styling with a Cool Air Blast

After you’ve finished styling your hair, give it a blast of cold air with your hair dryer. This helps to reduce frizz by sealing the cuticle and locking in precious moisture.

Trim Regularly to Maintain Healthy Ends

Split ends can lead to further breakage and damage, making hair appear frizzy and less healthy. Aim to get a trim every 6-8 weeks to maintain shape, and limit damage.

Adapt Your Routine to the Weather and Water Quality

Humidity, hard water, and seasonal changes can all affect how your hair behaves and absorbs products. So it is important to adapt your frizzy hair care routine to suit the conditions.
Humid weather: use anti-frizz serums and lightweight stylers
Cold climates: switch to richer conditioners and protective treatments
Hard water: regularly use a cleansing shampoo like Pure Clean to remove mineral buildup and purify your hair

How to Prevent Frizzy Hair

In this section, we look at some easy things you can incorporate into your frizzy hair care routine.

Protect Hair While Sleeping

To help maintain moisture levels, and prevent tangles and breakage, consider nighttime braiding styles (just like grandma). Loose bun styles (e.g. the pineappling technique) wrapped in soft cloth are another good option to minimize frizzy hair. Finally, ditch your cotton pillowcases and opt for silk or satin ones as they cause less friction, which in turn helps prevent breakage and damage.

Environmental Tips

UV exposure, humidity, chlorine, and pollution can all weaken hair and contribute to frizz.
Pro tips:
• Wear a wide-brimmed hat to reduce sun exposure, or consider braided styles or buns
• Always rinse hair after swimming or wear a swim cap
• Use protective leave-in products
• Choose hair care products containing antioxidants to help neutralize the damage caused by pollution

Healthy Nutrition for Strong Hair

Healthy hair starts with a healthy diet. Eating the right foods can influence hair growth, shine, and resilience. Incorporate these foods into your diet to improve hair health and combat frizzy hair:
Omega-3 Fatty Acids: salmon and other oily fish, flaxseed, chia seeds, walnuts, soybeans, spinach, and Brussels sprouts.
Biotin-rich foods: egg yolks, organ meats, nuts, seeds, sweet potatoes, spinach, mushrooms, avocados, and legumes.
Vitamin supplements: B Vitamins are vital for hair growth and strength. Vitamin A is important for healthy scalp oils, Vitamins C and E are powerful antioxidants.
Pro tip: make sure you keep well-hydrated.
