The best shampoo for curly hair is sulfate-free, matched to your hair porosity, and formulated to cleanse without stripping the natural oils your curls need to stay moisturized and defined.
Most drugstore shampoos contain sulfates — harsh detergents that strip curly hair of its natural oils, leaving it dry, frizzy, and prone to breakage. If your curls feel like straw after washing, your shampoo is likely the problem. This guide breaks down exactly what to look for and which shampoos actually work for natural, curly, and coily hair.
Why Sulfates Are Damaging for Curly Hair
Sulfates like sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES) are powerful cleansing agents that create a rich lather — but they are far too aggressive for curly hair. Curly and coily hair is naturally drier than straight hair because the curl pattern makes it harder for scalp oils to travel down the hair shaft. Sulfates strip away what little moisture curly hair retains, leading to:
- Chronic dryness and frizz
- Breakage and split ends
- Scalp irritation and flaking
- Color fading in color-treated hair
- Loss of curl definition
What to Look for in a Curly Hair Shampoo
- Sulfate-free formula — no SLS or SLES
- Moisturizing ingredients — aloe vera, glycerin, shea butter, or plant oils
- Porosity-matched — lightweight for low porosity, richer for high porosity
- Scalp-friendly — no parabens, no synthetic fragrance
- pH balanced — helps keep the cuticle smooth and sealed
Moisturizing vs Clarifying: Which Do You Need?
Curly hair needs two types of shampoo in rotation — a moisturizing shampoo for regular wash days and a clarifying shampoo for deep cleansing when product buildup accumulates.
| Shampoo Type | When to Use | Best For |
|---|---|---|
| Moisturizing Shampoo | Every wash day (1–2x per week) | Daily cleansing, maintaining moisture |
| Clarifying Shampoo | Every 2–4 weeks | Removing buildup, resetting the scalp |

Shop GrowPoo Clarifying ShampooHow Often Should You Wash Curly Hair?
Most curly hair types do best with 1–2 wash days per week. Washing too frequently strips moisture; washing too infrequently leads to buildup and scalp issues. Low porosity hair can often go longer between washes, while high porosity hair may need more frequent moisture replenishment.

A great shampoo is just the start. For maximum moisture retention and curl definition, follow this routine:
- Step 1 — Pre-Poo: Apply the Re-DO PrePoo before shampooing to protect hair from moisture loss during cleansing

- Step 3 — Condition: Follow with The Condish for deep moisture or protein replenishment
- Step 4 — Leave-In: Apply Hair Dew Leave-In matched to your porosity

Frequently Asked Questions
What is the best sulfate-free shampoo for curly hair?
The best sulfate-free shampoo for curly hair is one matched to your hair porosity. OrganiGrowHairCo's GrowPoo Moisturizing Shampoo is formulated for all porosity types and cleanses without stripping moisture from curly or coily hair.
How often should I use a clarifying shampoo on curly hair?
Use a clarifying shampoo every 2–4 weeks to remove product buildup and reset the scalp. Using it too frequently can dry out curly hair. Alternate with a moisturizing shampoo on regular wash days.
Can I use regular shampoo on natural hair?
Most regular shampoos contain sulfates that are too harsh for natural, curly, or coily hair. They strip the hair of its natural oils and cause dryness, frizz, and breakage over time. A sulfate-free shampoo formulated for curly hair is strongly recommended.
Is it okay to shampoo natural hair every week?
Yes, with a gentle sulfate-free shampoo like GrowPoo Moisturizing Shampoo, weekly washing is fine and actually recommended to keep the scalp clean and healthy. Always follow with a conditioner and leave-in to restore moisture.
What ingredients should I avoid in shampoo for curly hair?
Avoid sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), parabens, synthetic fragrance, and alcohol-based ingredients. These strip moisture, irritate the scalp, and disrupt the curl pattern over time.

Yes. GrowPoo Moisturizing Shampoo and GrowPoo Clarifying Shampoo are formulated for all curl types — from wavy (2a–2c) to coily (4a–4c). The porosity-based bundles help you build a complete routine around your specific hair needs.
