Credit: Kaboompics.comIf you have curly or wavy hair and are looking for a gentler, healthier way to wash it, you need to know about low poo. This cleansing technique is part of the curly girl method and is ideal for anyone who wants clean, defined curls without the dryness caused by harsh shampoos.
Low poo in the curly girl method focuses on using shampoos with gentle cleansers that clean the scalp without stripping natural oils. Choosing the right low poo shampoo is key to maintaining hydration, curl definition, and overall hair health.
Below, you’ll learn exactly what low poo is, how it differs from other CGM cleansing methods, and how to do it correctly.
What is low poo?
Low poo is a hair-washing method that uses shampoos formulated with mild cleansing agents instead of strong sulfates. The goal is to cleanse the scalp while preserving the natural oils that curly hair needs to stay hydrated and defined.
Unlike traditional shampoos, low poo cleans without leaving curls dry, rough, or frizzy.
Differences between low poo, co-wash, and final wash
These three techniques are all used to cleanse the scalp in the curly girl method, but they serve different purposes:
Low poo
Uses a gentle shampoo without strong sulfates or water-insoluble silicones.
Co-wash
Cleanses the scalp using conditioner only, without shampoo.
Clarifying or Final Wash
A one-time wash with a sulfate-containing shampoo (but no silicones) before starting the curly method (or everytime your hair need a reset).
You can learn more about the full routine in our guide to the curly girl method.
Why is low poo ideal for curls?
Curly and wavy hair tend to be naturally drier because scalp oils don’t travel easily down the hair shaft. Traditional shampoos with sulfates can make this worse by removing too much moisture.
In the curly girl method, low poo helps:
- Maintain natural hydration
- Reduce frizz
- Keep curls soft and defined
- Support a healthier scalp over time
How to do low poo correctly
Choose the right low poo shampoo for the curly girl method
When choosing a low poo shampoo, look for formulas that:
- Do not contain strong sulfates like Sodium Lauryl Sulfate or Sodium Laureth Sulfate
- Are free of water-insoluble silicones such as Dimethicone
- Do not include drying alcohols like Alcohol Denat or Isopropyl Alcohol
