When frizz happens, it can make us feel like we’re having a less than perfect hair day. Hair frizz is a phenomenon where individual strands of hair stand out from the rest of the hair. This occurs when your hair is searching for moisture, but instead of finding it internally or within the strand, it finds it in the air.
Curly hair is naturally more prone to frizz because of its structure. The bends and coils make it harder for natural oils to travel from root to tip, leaving strands more vulnerable to things like dryness and damage.
When the outer layer of the hair, or hair cuticle, is compromised, moisture from the environment enters the strand. This can cause swelling, uneven texture, and that frustrating halo of frizz.
Why Curly Hair Gets Frizzy More Easily
Curly hair is naturally delicate due to its structure, making it more prone to frizz than straighter textures. The twists and bends in each strand create uneven points along the cuticle, making it harder for natural oils to coat the hair evenly. As a result, curls tend to be drier, more porous, and more reactive to environmental stressors like humidity. Understanding why curly hair behaves this way is key to shopping by specific hair goal, so you can focus on building a routine that supports smoother, more defined curls.
So what are some factors that cause frizz in curly hair?
1. Lack of Moisture
Curly hair loses hydration faster than straight hair. Without enough moisture, strands become rough, dry, and more prone to frizz.
2. Cuticle Damage
Heat styling, color treatments, and environmental stressors can weaken the cuticle, making it easier for humidity to penetrate the hair shaft.
3. Humidity Exposure
Humidity disrupts the curl pattern by forcing moisture into dry strands, causing them to expand unevenly.
4. Product Buildup or Harsh Cleansing
Using overly stripping shampoos can remove essential oils, while buildup can block hydration from entering the hair.
How Can Shampoo Help with Frizz?
Not all shampoos are created equal, especially when it comes to curly, frizzy hair.
The best hydrating shampoo for frizzy hair should:
-
Gently cleanse without stripping the hair of natural oils
-
Deliver lasting hydration
-
Support curl definition
-
Strengthen hair structure at a deeper level to support foundational hair health
Frizz isn’t just a surface issue, it’s a structural one, which is why addressing internal hair bonds is key to long-term results.

Using both a shampoo and conditioner as a system can help amplify results, especially for curly textures that need more consistent moisture and repair.
Other Curly Hair Habits to Reduce Frizz
In addition to your daily wash routine, everyday habits play a major role in how your curls look and feel. Small changes to how you handle, dry, and protect your hair can help minimize frizz and maintain definition between washes.
Here are some tips to get you started:
-
Switch to a microfiber towel or cotton t-shirt: Traditional towels can rough up the cuticle, only leading to more frizz.
-
Avoid brushing dry curls: Brushing dry hair can separate the curls and create unwanted volume. Try to detangle only when the hair is wet and properly conditioned.
-
Add weekly hair masks to your routine: Incorporating a weekly treatment like the Rich Hydration Mask, can help go beyond surface hydration and strengthen hair from deeper within.
-
Limit heat styling: Frequent heat use can weaken the hair’s structure over time, increasing dryness and making frizz harder to control.
Consistent care both in and out of the shower helps support healthier curls that are more resilient to frizz, humidity, and daily stressors.
