Smooth, seal, and shield your ends — in 2 to 5 drops.
A weightless leave-in serum with a built-in UV shield.
Molecular Reconstructor wraps every strand in a featherlight silicone veil — instantly smoothing frizz, sealing the look of split ends, and helping shield hair from the sun's fading, drying effects.
"For clients with dry, sun-stressed, or color-treated ends, this is the finishing step — it makes the hair instantly smoother and shinier, and the UV filters help their color hold longer between visits."
Damaged ends don't just look dry — they catch the light wrong, tangle, and snap.
Molecular Reconstructor is a lightweight, leave-in "dry-oil" serum that wraps each strand in a weightless silicone veil. It instantly smooths the cuticle, seals the look of split ends, and tames frizz for a soft, glassy finish — while a built-in system of UV filters helps shield your hair, especially color-treated hair, from the sun's fading and drying effects. A few drops through damp ends, and brittle, dull, flyaway strands turn silky and light-catching — with no greasy weight and no residue.
How a silicone serum smooths and seals
Damaged, frizzy hair has a raised, roughened cuticle — that's what scatters light (dullness), grabs humidity (frizz), and frays into split ends. This serum's silicone duo works by physics: the volatile carrier spreads a microscopic, even film across each strand, then evaporates, leaving behind a weightless veil that lies the cuticle flat. That film smooths the surface, seals the look of split ends, blocks humidity, and reflects light for shine — a cosmetic finish that transforms how hair looks and feels, without weighing it down.
Inside the formula
Cyclopentasiloxane & Dimethiconol
A lightweight film-forming duo — spreads evenly, seals the cuticle, then evaporates clean to leave a silky, glass-like finish that reflects light.
Ethylhexyl Methoxycinnamate, Benzophenone-3 & Homosalate
Three UV filters that work at the hair's surface to help shield strands — especially color-treated hair — from UV-driven fade, brittleness, and dryness.
Isopropyl Myristate
Gives the serum effortless slip and spreadability, so just a few drops glide through and cover the whole head evenly.
Anhydrous "Dry-Oil" Base
No water, no fillers — a concentrated serum that absorbs clean, never greasy, never heavy, never crunchy.
Sulfate-Free & Paraben-Free
Formulated without sulfates or parabens — a gentle finishing step for color-treated and chemically processed hair.
Dermotricology Finishing Serum
Part of the Kapyderm system, formulated in Spain over 35+ years of dermatological practice.

What is Molecular Reconstructor?
It's a lightweight, leave-in "dry-oil" silicone serum for dry, frizzy, or split-prone hair. It smooths the cuticle, seals the look of split ends, adds shine, and includes UV filters that help shield hair from the sun.
Does it actually repair or rebuild my hair?
It works cosmetically at the surface — the silicone film smooths and seals damaged ends so hair looks and feels healthier, softer, and shinier. It's a finishing serum that improves the look and feel of damage, not a treatment that biologically rebuilds the fiber.
How does the UV protection work?
The serum contains UV filters that sit on the hair's surface and help shield strands — especially color-treated hair — from UV-driven fading, dryness, and brittleness. It protects your hair, not your skin, and isn't a sunscreen with an SPF.
How much should I use?
Just 2 to 5 drops — more for long or thick hair, less for fine hair. It's concentrated and water-free, so a little covers a lot. Too much on fine hair can weigh it down.
Is it good for color-treated hair?
Yes — it's sulfate-free and paraben-free, and the UV filters help color-treated and bleached hair resist sun-driven fade. Use it on damp or dry hair as a finishing step.
How should I store it / how long after opening?
Period after opening is 12 months. Store cool and dry, away from direct sunlight and heat.
