NOURISHING Keratin Sealer
Davines Naturaltech NOURISHING Keratin Sealer is a leave-in protective fluid with Vegetal Keratin and Hydrogenated Farnesene that seals the hair cuticle after every NOURISHING treatment — increasing brightness and softness, strengthening the fibre, and preventing split ends.
The Moda Team Review: The Step That Locks In Everything Else
The Keratin Sealer is the last step of the NOURISHING routine — applied to towel-dried hair after rinsing out the Miracle Conditioner or Miracle Mask, distributed with a comb, and left in. It's not a styling product, and it's not optional if the client wants the best possible result from the system. Think of it as the seal: once the Vegetal Keratin from the Hair Building Pak and the Miracle finisher have done their structural work, the Sealer closes the cuticle over the top, preventing that repair from being disrupted by environmental exposure, friction, or heat during styling.
The result is an immediate and noticeable increase in shine and softness — clients often comment that their hair has never looked as glossy. It also provides a protective, anti-breakage layer that keeps split ends from forming and keeps styled hair from reverting quickly. It's lightweight enough to leave in without heaviness and doesn't interfere with blow-drying or any styling product used after. Davines is explicit: use it every time any NOURISHING treatment is completed, both at home and in salon.
Key Active Ingredient
Vegetal Keratin (Hydrolyzed Rice Protein + Glycine + Lysine HCL) — In leave-in form, Vegetal Keratin works on the outer cuticle surface to fill in micro-gaps and create a smooth, sealed surface that reflects light and resists friction damage. Paired with Hydrogenated Farnesene — a plant-derived emollient with excellent cuticle-sealing properties — the formula creates a thin protective film over the hair shaft that retains moisture, increases softness, and prevents split end formation without the build-up or heaviness of traditional leave-in oils.
Moda Pro Tip
Distribute it with a wide-tooth comb from mid-lengths to ends immediately after towel-drying — before any heat tool touches the hair. The cuticle-sealing effect of the Farnesene is most effective when applied to cool, damp hair, and the comb ensures even distribution across every strand so the protective film forms uniformly rather than in patches.
How To Use
- Complete your NOURISHING routine: shampoo → Pak (if using) → Miracle Conditioner or Mask.
- Towel-dry hair to remove excess water.
- Apply the Keratin Sealer evenly to towel-dried lengths and ends.
- Distribute with a comb — do not rinse.
- Style as usual.
- Use every time you complete a NOURISHING treatment, both at home and in salon.
Frequently Asked Questions
When exactly do I use the Davines Naturaltech NOURISHING Keratin Sealer in the routine?
It's the last step — applied after rinsing out the Miracle Conditioner or Miracle Mask, to towel-dried hair, and left in. Davines instructs using it every time a NOURISHING treatment is completed, including at-home washes.
Is the Davines NOURISHING Keratin Sealer a rinse-out or leave-in product?
It's a leave-in. Do not rinse it out. It stays on the hair throughout styling and wear, providing ongoing cuticle protection and split-end prevention.
Does the Davines Naturaltech NOURISHING Keratin Sealer weigh fine hair down?
No. Its fluid texture is lightweight and distributes with a comb into a thin, even film. It doesn't create heaviness or build-up, making it appropriate for all hair types including fine hair.
Can I use heat tools after applying the Davines NOURISHING Keratin Sealer?
Yes. Apply it before blow-drying or heat styling. The cuticle-sealing protective layer helps shield the hair from heat-related friction and moisture loss during the styling process.
What does Hydrogenated Farnesene do in the Davines NOURISHING Keratin Sealer?
Hydrogenated Farnesene is a plant-derived emollient that forms a smooth protective film over the hair cuticle. It seals moisture in, increases softness and shine, and creates a barrier that prevents split end formation and environmental damage.
