Description

A sulphate-free curl cleansing shampoo with Organic Oat Milk and Avocado Oil that hydrates while it cleanses — reinforcing the moisture bonds in wavy, curly and coily hair to reduce breakage and improve definition without stripping natural oils.

The Moda Team Review

The biggest problem with traditional shampoos on curly or wavy hair is that sulphate surfactants strip the natural oils that hold curl pattern together and prevent frizz. Killer Curls Wash is built on sulphate-free surfactants specifically selected for curl types — it cleanses the scalp thoroughly without stripping the shaft, which preserves both moisture and pattern integrity through the wash step. Organic Oat Milk deposits amino acids and proteins that reinforce the hair’s moisture bonds during cleansing. Avocado Oil penetrates the cortex and delivers essential fatty acids that keep curls flexible, reducing breakage from the combing and manipulation that follows.

The result is a shampoo that prepares curly hair for the conditioning and styling steps rather than undoing the work they need to do. Hair that comes out of a sulphate wash is working against itself from the first step. Hair that comes out of Killer Curls Wash is already set up for definition and hydration before the conditioner is even applied.

Why Moda Carries This

As a White Haven Kevin Murphy salon, we recommend Killer Curls Wash for every wavy, curly or coily client who is still using a standard shampoo. The sulphate-free cleanse is not just a preference for curl types — it is a foundational requirement. Kevin Murphy built this formula from the understanding that curl care starts in the shower, and that a properly formulated cleanse is the step that everything downstream depends on.

Key Active Ingredients

  • Organic Oat Milk: Deposits amino acids and proteins that reinforce the moisture bonds in curly hair during cleansing. Adds slip and reduces friction during the wash step.
  • Persea Gratissima (Avocado) Oil: Penetrates the cortex to deliver essential fatty acids that keep curls flexible and reduce breakage from manipulation.
  • Sulphate-free surfactant system: Cleanses the scalp thoroughly without stripping the shaft oils that hold curl pattern and prevent frizz.

Moda Pro Tip

Apply with warm water and focus the massage at the scalp only — the surfactant system is gentle enough that the rinse will carry it through the lengths without direct application. This minimises friction on fragile curl strands during the cleanse step, which is where a significant amount of mechanical breakage happens on curl types. Follow immediately with Killer Curls Rinse before the hair dries out.

Not the Right Fit If...

If you have straight or fine hair, Killer Curls Wash is formulated for wavy to coily textures and will be richer than straight hair typically needs. For fine wavy hair that needs both curl definition and volume, Angel Wash may be a better daily choice with Killer Curls Rinse on the lengths.

How To Use

  1. Apply to wet hair and massage gently into the scalp only.
  2. Let the rinse carry the formula through the lengths.
  3. Rinse thoroughly.
  4. Repeat only if hair has heavy product buildup from gel or cream stylers.
  5. Follow immediately with Killer Curls Rinse while hair is still wet.
COMMON QUESTIONS

Product FAQ

Yes — and the shampoo step is usually where the problem starts. Sulphate surfactants strip the shaft oils that hold curl pattern together. Killer Curls Wash uses sulphate-free surfactants with Organic Oat Milk and Avocado Oil to cleanse without stripping, so your conditioner and styler have something to build on rather than repair.
Possibly — it depends on how fine and how wavy. Killer Curls Wash is formulated for wavy to coily textures and has a richer feel than a volumising shampoo. If your hair is both fine and wavy and volume is a concern, Angel Wash may be a better daily fit, with Killer Curls Rinse applied to the lengths only.
Yes — the litre works out to significantly better value per wash, and curly hair routines use more product per application than straight hair. At twice-weekly washing, a 1000ml typically lasts five to six months. If you want to try the formula first, start with the 250ml.
Yes, with technique. Apply Killer Curls Wash only at the scalp and let the rinse carry it through the lengths. If your scalp is very oily, double-shampoo at the root on wash day — but keep the second pass away from the dry ends entirely.
Yes — it matters more than most people realise. A sulphate-based cleanser before Killer Curls Rinse strips what the conditioner is trying to restore. Using Killer Curls Wash first means the conditioner is building on a prepared base rather than compensating for the cleanse step.
