Black seed oil (Nigella Sativa) is cold-pressed from black cumin seeds and is naturally rich in thymoquinone, an active compound known for its anti-inflammatory and antioxidant properties. In hair care, it works to strengthen roots, nourish the scalp, reduce shedding and breakage, and soothe scalp conditions like dryness and irritation. Both the shampoo and conditioner in this duo are formulated with organic black seed oil to support long-term scalp and follicle health with every wash.

Yes. The Black Seed & Turmeric Shampoo is completely sulfate-free and SLS-free. Instead of harsh detergents, it's formulated with Decyl Glucoside and Lauryl Glucoside — COSMOS Organic and ISO 16128 compliant, plant-derived surfactants that gently lift oil, buildup, and residue without stripping your scalp's natural moisture barrier. This makes it gentle enough for daily use, even for those with sensitive or reactive scalps.

AminoSensyl™ HC is a patented, 100% natural conditioning technology that uses a unique positive-and-negative charge bonding system to coat and condition each hair fiber for up to 24 hours. Unlike synthetic quats (quaternary ammonium compounds) found in most conventional conditioners — which can build up and cause long-term damage — AminoSensyl HC is completely quat-free and biodegradable. It delivers salon-grade slip, smoothness, and lasting hydration using only natural, plant-derived chemistry. Noun Naturals is among the first hair care brands in the world to use it.

Yes! From straight hair to wavy, curly, and coily, this conditioner is made for every hair type. And if you’re wondering specifically about curly hair, the answer is also yes. With our patented natural conditioning system, this is guaranteed to be the strongest and highest-performing natural conditioner you’ll ever use.,

Absolutely. Our conditioner is 100% COSMOS Organic, non-toxic, quat-free, and paraben-free. It’s gentle enough for sensitive scalps while still delivering salon-level performance, without the harsh chemicals that often cause dryness or irritation.

Yes. Because this duo is free from sulfates, SLS, harsh salts, and silicones, it is color-safe. Sulfates are one of the leading causes of color fading in chemically treated hair, as they can strip the hair shaft and accelerate dye loss. The gentle glucoside-based surfactants used in this shampoo cleanse without penetrating or disrupting the hair cuticle, helping maintain vibrancy and prolong your color treatment.

This duo uses absolutely no synthetic fragrance. Instead, it's scented entirely with Japanese peppermint and eucalyptus blue mallee essential oils, which provide a refreshing, cooling, and uplifting scent during every wash. For most fragrance-sensitive individuals, natural essential oil scents are far better tolerated than synthetic parfum. However, those with known sensitivities to peppermint or eucalyptus essential oils should review the full ingredient list before use.

Most products labeled "natural" are not verified by a third party and may still contain synthetic preservatives, fragrance, or surfactants. The Noun Naturals Hero Duo is different because every single ingredient is 100% COSMOS Certified, developed by an in-house R&D team guided by chemists with over 40 years of formulation expertise. The formulas are built on an aloe vera juice base (not water), use EU-manufactured ISO 16128 compliant surfactants, and feature breakthrough natural technologies like AminoSensyl™ HC — setting a higher bar than almost anything else available in the natural hair care market.
