Technology

Where science meets real hair

Healthy hair isn't built on the surface. It starts within.

Nano-capsule delivery system

Beyond what you can see

At Stephen Knoll New York, every formula is designed to work beyond what you can see, targeting the internal structure of the hair fiber, where real damage lives.

Our signature technology is built around advanced nano-capsules, microscopic carriers that deliver active ingredients deep into the hair. Instead of coating the surface, these capsules penetrate the fiber to repair, hydrate, and reinforce from within.

Targeted delivery to damaged areas

Deeper absorption of active ingredients

Longer-lasting results with every use

Four specialized capsule systems

Each product uses a precise function

Four capsule technologies, each engineered for one job, and the products built around them.

Reset & purify

Detox Capsules

Remove buildup, pollution, and daily stressors from the hair and scalp.

Cleansing comes first. Product residue, hard water and city air sit on the scalp and flatten the fiber.
Detox capsules clear that layer so everything that follows can actually reach the hair.

Strengthen & restore

Rapid Repair Capsules

Deliver proteins and lipids deep into the hair core to repair damage quickly.
Where heat, color and friction have broken bonds, repair capsules carry proteins and lipids straight
to the cortex. Strength returns from the core, not from a coating on the outside.

Rebuild structure

Inner Stock Capsules

Rebuild the internal structure of the hair with ceramides and strengthening agents.
Ceramides restock what the fiber has lost, restoring elasticity and the ability to hold a shape.
Hair regains body and movement instead of falling flat by mid-afternoon.

Hydrate & seal

Hydro Renew Capsules

Lock in moisture and protect against heat and environmental stress.

The last step seals the cuticle, holding moisture inside and humidity out.

This is where glass-like shine comes from, and where a blowout learns to last.

Designed around hair stressors

Hair is constantly under attack

Our technology is designed to neutralize these stressors, restoring balance, strength, and resilience over time.

Heat styling

Chemical treatments

Environmental exposure

Daily friction and brushing

THE RESULT

HAIR, RESTORED FROM WITHIN

This is not surface care.

Stronger at its core
Easier to manage and style
Softer on the surface
Naturally radiant, without buildup
