NULASTIN NuProtect Leave-In Hair Primer & Heat Protectant Spray, 5 oz — Detangles, Strengthens to 450°F

Designed for daily styling and midweek refreshes, this lightweight 5 oz spray restores manageability while protecting hair structure. Formulated with Biodesigned Elastin and Vegan Biodesigned Keratin, the mist supports strengthened strands and smoother surfaces without weighing hair down. It works as a primer before heat tools and as a leave-in conditioner to reduce breakage, tame frizz, and boost shine for healthier-looking hair over time.

How does NuProtect reduce breakage and strengthen hair?

The formula rebuilds weakened areas of the hair shaft by depositing proteins and elastin analogs that reinforce internal structure. With repeated use the hair feels more resilient and resists snapping during brushing and styling. Clinical testing shows a measurable decline in breakage after application.

• Biodesigned Elastin helps restore elasticity lost from chemical or heat damage.
• Vegan Biodesigned Keratin supports fiber reinforcement and surface smoothness.
• Regular use reduces breakage and improves manageability.

Can I use this spray before heat styling and how hot can it protect against?

Yes — NuProtect doubles as a heat protectant and a detangling primer. It forms a protective layer over each strand to reduce thermal stress and helps hair glide under brushes and irons. The spray is designed to withstand styling tools up to 450°F when used as directed.

• Apply to damp mid-lengths and ends prior to blow-drying or hot tools.
• Helps prevent moisture loss and heat-related roughness.
• Compatible with blow dryers, flat irons, and curling wands up to 450°F.

What benefits will I notice right away versus over time?

Immediately you should see easier detangling, reduced flyaways, and improved shine — ideal for quick morning routines. Ongoing use builds structural support within the hair fiber, leading to less breakage, softer texture, and more consistent styling results. The product functions both as a daily cosmetic boost and a cumulative restorative treatment.

• Instant: smoother surface, reduced frizz, easier comb-through.
• Short term: easier styling and less breakage during manipulation.
• Long term: reinforced hair structure, increased softness, durable manageability.

How do I incorporate this spray into my hair routine?

Use NuProtect after shampoo and conditioner on clean, damp hair — spray mid-lengths and ends and comb through before styling; no rinsing required. It also works between washes to refresh shape and tame humidity. Pairing it with NULASTIN shampoo and conditioner enhances cumulative strengthening benefits.

• Spray evenly on damp hair, focusing on mid-lengths to ends.
• Comb through, then blow-dry or style as usual; reapply lightly between washes if needed.
• Combine with NULASTIN wash products to maintain hair integrity over time.

Who is this for: NuProtect is suited for anyone whose hair experiences heat or styling stress, color-treated or chemically altered hair, and people looking for an everyday leave-in that detangles, protects, and gradually rebuilds strength. It is lightweight enough for fine hair yet effective on thicker, coarser textures, making it a versatile choice for routine care and targeted repair.
