CGM for wavy hair: how to use the Curly Girl Method on type 2 waves
CGM for wavy hair means avoiding sulfates, silicones, and heat. Instead, wash with a gentle sulfate-free shampoo bar, apply conditioner to wet hair, and dry using plopping or a diffuser on low heat to bring out the natural shape of type 2 waves.
Type 2 wavy hair lives in a constant tension between potential and frustration. The waves are there, soft S-shapes that promise definition and movement, but they easily disappear as they dry or get flattened by the wrong products. The Curly Girl Method is the answer to that frustration, and it works just as well for type 2 waves as it does for curly hair.
The Curly Girl Method, or CGM, was originally created for curly hair but has proven just as transformative for type 2 wavy hair. The difference is that type 2 waves are finer and more sensitive to weight, which calls for a lighter hand with products and an understanding of how the hair cuticle responds to different ingredients.
What is CGM, and why does it work for wavy hair?
The Curly Girl Method is based on three core principles: cleanse gently, moisturize consistently, and dry without friction. For type 2 wavy hair, it’s mainly about no longer disrupting the hair’s natural movement pattern.
Sulfates, such as sodium lauryl sulfate (SLS), are strong surfactants that cleanse effectively but also strip away the hair’s natural oils and open the cuticle. When the cuticle is open and disturbed, waves lose their definition and the hair dries out quickly. Silicones coat the cuticle and provide temporary shine, but build up residue that requires strong sulfates to wash away. It’s a vicious cycle that CGM breaks.
A sulfate-free shampoo bar made with mild surfactants such as Sodium Cocoyl Isethionate effectively cleanses the scalp without disrupting the cuticle’s natural structure. That’s exactly what wavy hair needs to retain its shape and moisture.
The CGM routine for type 2 waves, step by step
Type 2 wavy hair is finer than curly hair and reacts quickly to too much product. Keep the routine light and consistent.
| Step | What to do | Why |
|---|---|---|
| 1. Lather up | Lather the sulfate-free shampoo bar in your hands, then apply it to your scalp using circular motions | Cleanses without disrupting the cuticle or drying out the strands |
| 2. Rinse with cool water | Finish rinsing with cooler water | Closes the cuticle and preserves the shape of the waves |
| 3. Condition the lengths | Apply a conditioner bar to soaking-wet hair, focusing on the lengths and ends | Moisturizes and prepares the hair for drying |
| 4. Plop | Wrap your hair in a microfiber towel for 10-20 minutes | Removes excess water without disturbing the wave pattern |
| 5. Dry | Air-dry or diffuse on low heat and low airflow | Preserves definition and minimizes frizz |
The most important thing to remember: don’t touch your hair while it’s drying. This is the most common cause of frizz in wavy hair.
Editor's Note: Type 2 waves are more sensitive to weight than curly hair. Always start with a small amount of conditioner and increase gradually. Less is often more when it comes to preserving volume at the roots.

Common mistakes when starting CGM for wavy hair
- Too much product: Type 2 waves don’t like weight. Start with a small amount of conditioner and add more if your hair feels dry.
- Rubbing with a towel: Friction is the enemy of wavy hair. Always use a microfiber towel or a cotton T-shirt and gently scrunch.
- Skipping plopping: Plopping is the single most effective step for lifting waves at the roots and reducing drying time.
- Giving up too soon: Hair needs 2-4 washes to adjust after silicones and sulfates. Results improve with every wash.
