Davines Nourishing Keratin Sealer leave-in, protective & strengthening — lightweight for dry, damaged hair

This protective, strengthening finishing fluid is formulated to lock in the results of your Nourishing routine. Enriched with vegetal keratin and amino acids, the sealer targets dry, brittle and damaged hair by smoothing the cuticle layer and helping prevent split ends. Its featherlight texture layers comfortably under styling without weighing hair down.

How does this leave-in protect and strengthen hair?

The Sealer forms a thin, smoothing film over each strand to reduce roughness and protect the hair surface from friction and styling stress. Vegetal keratin and amino acids integrate with weakened fiber to support elasticity and reduce breakage potential. Use after your Nourishing shampoo, mask and conditioner to preserve those benefits between washes.

• Vegetal keratin replenishes protein-like structure
• Amino acids help improve fiber cohesion and flexibility
• Light film reduces cuticle lift and surface porosity
• Prevents mechanical damage during combing and styling

How do I apply it for best results?

Work a few drops into towel-dried hair immediately after completing your Nourishing regimen, distributing evenly with a comb from mid-lengths to ends. No need to rinse; follow with your usual styling products and tools. The product’s lightweight feel avoids greasiness even when used daily.

• Apply to towel-dried hair only—avoid soaking wet strands
• Use a comb to ensure even coverage and target ends
• Adjust amount by hair thickness: start small and add if needed
• Layer under heat protectants or styling creams as required

What visible improvements can I expect and when?

Immediate results typically include reduced frizz, easier detangling and a glossier surface. Continued use as the final step in the Nourishing sequence helps minimize split ends and supports a stronger feel over weeks. Results vary with hair condition and frequency of styling.

• Instant: smoother cuticle and improved shine
• Short term: less breakage when combing and styling
• Ongoing: improved manageability and reduced split-end appearance
• Compliments the rest of the Nourishing line for cumulative effect

Who is this for: Ideal for people with dry, brittle or chemically treated hair who want a non-greasy finishing product to seal in nourishment and make styling easier. It suits those who follow the Davines Nourishing routine and need a lightweight protective layer to enhance softness, brightness and fiber resilience without weighing hair down.

Directions: Apply on towel-dried hair after your Nourishing routine, distribute evenly with a comb, then style as usual.
