Hair doesn't heal.
It has to be rebuilt.
Hair is not living tissue. Once a fiber is damaged, it cannot regenerate itself the way skin does. Everything Nera³ makes is built around that fact - preserve what is healthy, replace what has been lost, and protect the result from the next wash, the next iron, the next summer.
Nourish. Strengthen. Protect.
A single formula cannot clean, hydrate, strengthen and protect equally well. Asking it to do all four usually means each job gets done partially. The ritual treats them as three distinct acts, in the order the hair can actually use them.
Nourish
Moisture and nutrients go in where they stay in. The rich ingredients are reserved for the steps that remain in the hair - the conditioner and the conditioning spray - not the shampoo, where they would rinse away in seconds.
Strengthen
The workhorse of the ritual, applied after the conditioner so it distributes evenly instead of in patches. Three proteins work at different depths, and a bond-repair complex restores the internal bonds that hold the strand together.
Protect
Repair only lasts if the day does not undo it - the dryer, the iron, the sun, and everything in between. The finish holds what the first two steps put back.
Three products, three depths. The conditioner works across the fibrous layers, the treatment reaches the cortex, and the finishing spray stays at the cuticle where the day does its damage.
Damage happens at more than one depth.
Color, heat and extensions wear the strand down in two different ways - at the surface and deep inside. A treatment that only reaches one of them leaves the other untouched.
Deep cortex bond repair
Targets the deepest layer of the strand to rebuild broken bonds and restore structural integrity.
Mid-level fiber reinforcement
Strengthens the mid-shaft structure, supporting elasticity and helping fragile strands withstand daily styling stress.
Shaft-sealing proteins
Lightweight proteins strengthen the hair shaft, improving texture and manageability and reducing breakage from brushing and styling.
Sealing conditioner
Hydrating conditioners seal the cuticle layer, locking in moisture while protecting hair from dryness and environmental stress.
What is in it,
and what it does.
Every product below is built from ingredients with documented results - what the material itself is shown to contribute, not a promise about a head of hair.
All Nera³ haircare products contain a DHT Blocker.
Finishing Spray
Vinylpyrrolidone Terpolymer (cationic film former)
Clinically documented- ·Forms a flexible hold film at low use levels
- ·Documented hold retention under high-humidity conditions
- ·Cationic charge deposits selectively on damaged, negatively charged fiber sites
The styling backbone of the formula. A cationic film-forming polymer that lays down a flexible film across the fiber, delivering body, lift, and hold that resists humidity without stiffness or flaking - and washes out cleanly on the next cleanse.
Cetrimonium Chloride
Clinically documented- ·Demonstrated significant reduction in static electricity
- ·Improves wet and dry combing performance
Adsorbs onto the fiber surface, forming a conditioning film that smooths the cuticle and neutralizes the static charge that causes flyaway. It also carries the formula evenly across the hair as it sprays.
Hydrolyzed Keratin Protein
Clinically documented- ·Up to 40% increase in hair tensile strength in damaged fibers
- ·Up to 50% reduction in mechanical breakage during brushing
- ·20–30% improvement in wet combing force
Low-molecular-weight peptides bind to damaged keratin sites within the cuticle and cortex, reinforcing weakened areas of the fiber. In a leave-on step, that reinforcement stays in place through drying, styling, and the rest of the day.
Hydrolyzed Silk Protein
Clinically documented- ·Up to 30% increase in measurable hair shine
- ·15–20% reduction in fiber-to-fiber friction
- ·10–15% improvement in moisture retention
Silk amino acids form a lightweight film across the cuticle surface, smoothing irregularities in the shaft. This improves light reflection and reduces the friction created by styling tools and daily wear.
Hydrolyzed Hemp Protein
Clinically documented- ·Contains approximately 65% edestin protein, structurally compatible with human keratin
- ·High levels of sulfur-containing amino acids, important for keratin cross-linking
Plant-derived amino acids that support the natural protein structure of the hair fiber while improving elasticity and resilience.
Hydroxypropylgluconamide (and) Hydroxypropylammonium Gluconate
Clinically documented- ·Up to 28% improvement in fiber strength in chemically damaged hair
- ·Up to 40% reduction in breakage after repeated treatments
- ·Demonstrated ability to restore internal hydrogen and ionic bonds
A bond-repair complex that penetrates into the cortex and helps rebuild the hydrogen and ionic bonds stabilizing the internal keratin matrix. Delivered in a leave-on base, it keeps working through the day rather than rinsing away.
C18-21 Alkane
Clinically documented- ·Plant-derived, readily biodegradable lightweight emollient
- ·Reduces combing friction and increases surface gloss
- ·Non-occlusive at use levels - no measurable buildup across repeated applications
A weightless plant-derived alternative to heavier silicone emollients. It contributes slip and gloss across the cuticle and helps the styling film lay down evenly, without the residue or weight that would flatten fine hair or load extension bonds.
Benzophenone-4
Clinically documented- ·Water-soluble UV absorber, active across the UVA/UVB range
- ·Documented reduction in photo-fading of artificially colored fibers
- ·Documented protection of formula color and fragrance from light degradation
A water-soluble UV filter that absorbs ultraviolet light before it reaches the fiber, helping preserve color tone and limiting the photo-oxidation that weakens the cuticle over time.

Dry Shampoo
Tapioca Starch
Documented- ·High sebum absorption capacity relative to particle weight
- ·Translucent on application - a soft-focus finish rather than a chalk layer
- ·Fine, silky particle feel
The primary absorbent. It takes up oil at the root where it actually shows, refreshing the style without the flat white cast that heavier powders leave behind.
Maranta Arundinacea Root Extract (Arrowroot)
Documented- ·Very fine particle size with documented absorbency
- ·Low visible residue on application
- ·Contributes a smooth, silky after-feel
A second botanical absorbent working alongside the tapioca starch, chosen for how completely it disappears into the hair. It refines the texture of the powder so the finish reads as clean hair, not as product.
Bentonite
Documented- ·Layered aluminosilicate clay with high cation exchange capacity
- ·Documented adsorption of sebum and surface impurities
- ·Long-established use in scalp and skin cleansing applications
Clay works differently than starch - its charged layered structure adsorbs oil and impurities and binds them, rather than simply soaking them up. That is what makes the refresh feel like a cleanse rather than a cover-up.
Fumed Silica
Documented- ·Extremely high surface area per unit weight
- ·Documented oil absorption and anti-caking performance
- ·Maintains free-flow in dry powder systems
It absorbs oil and keeps the powder loose and free-flowing, so the applicator delivers a fine, controlled dose to the root every time.
Ganoderma Lucidum Extract (Reishi)
Documented- ·Contains polysaccharides and triterpenes
- ·Antioxidant activity documented in laboratory studies
- ·Documented soothing profile in topical use
Reishi brings antioxidant support to the scalp on the days between washes - this step is about caring for the scalp environment, not only absorbing oil from the hair.
Rosmarinus Officinalis Leaf Extract (Rosemary)
Documented- ·Contains rosmarinic and carnosic acids
- ·Antioxidant activity documented in laboratory studies
A botanical antioxidant that supports a balanced, comfortable scalp environment between washes.
Theobroma Cacao Seed Extract (Cacao)
Documented- ·Contains polyphenol antioxidants
- ·Naturally pigmented extract
Cacao contributes antioxidant polyphenols, and its natural warm pigment helps the powder settle into deeper hair tones rather than sitting on top of them.
Moisturizing Shampoo
Our Moisturizing Shampoo doesn't carry any key clinical ingredients. Here's why.
Nera³ Moisturizing Shampoo is designed specifically for effective cleansing and scalp balance. As with every shampoo on the market, it is rinsed out of the hair within seconds. Other brands still put key - and more expensive - ingredients into the shampoo, where it quickly ends up in the drain. We intentionally reserve our clinically supported key ingredients for the strengthening and conditioning steps of the system, where they remain in the hair and can deliver real results.
Notable ingredients · gentle surfactants- Based on the renewable resources of corn and coconut
- Does not strip the hair completely clean of natural oils
- Low irritation, high foaming capacity
Balance, not extremes.
Does hair actually "heal" the way skin does?
No - hair is not living tissue, so once a fiber is damaged it cannot regenerate. The goal of the Nera³ system is to preserve what is healthy, minimize further damage, and keep hair in balance over time.
Can hair be over-treated?
Yes. Too much protein can leave hair brittle; too much moisture can leave it weak; over-cleansing strips it and under-cleansing causes buildup. The Nera³ system is built around balance, not extremes.
What makes a system different from a single product?
A single formula cannot clean, hydrate, strengthen and protect equally well - asking it to do so usually means each job gets done partially. The system treats each as a distinct step, timed to work with the hair rather than against it.
Why is there no protein in the shampoo?
Because it would be rinsed away within seconds. Key ingredients are placed in the steps that retain them, which is why the shampoos are built for cleansing and scalp balance instead.
The science is the whole set, in order.
Each step is formulated to hand off to the next. Used together, they do what none of them can do alone.
