Ouidad VitalCurl+ Leave-In Styling Hair Serum 8.5 oz — Lightweight Hydrating Serum for All Curl Types, Frizz Control & Shine

Designed by curl specialists, this 8.5 oz serum primes hair before styling, acts as a gentle air-dry styler, and doubles as a targeted overnight treatment. Its formulation blends niacinamide, biotin, peptides and a Botanical Omega 3-6-9 Complex to nourish curls and help maintain natural elasticity and shine. Free from silicones, parabens, sulfates and other common harsh ingredients, it’s made for everyday use across the full spectrum of curl patterns.

How will this serum change my curl routine?

The serum simplifies styling by combining conditioning and light hold in one step: apply to damp hair to detangle, define, and reduce frizz, or use sparingly on dry hair to tame flyaways. It speeds up air-drying routines and provides a hydrated base for additional products like gels or creams. The result is softer, more touchable curls that retain movement.

• Use as a leave-in primer before styling to improve manageability.
• Apply alone as a lightweight air-dry styler for low-maintenance looks.
• Layer under gels or creams for added moisture and definition.

What ingredients make it good for curly hair?

Key actives target hydration, strength, and scalp balance without weighing hair down. Niacinamide and biotin support hair resilience, peptides help with strand fortification, and the Botanical Omega 3-6-9 Complex helps restore lipids that retain moisture and bounce. The formula avoids heavy silicones and oils that can flatten or residue-build curls.

• Niacinamide and biotin for healthier-looking, stronger strands.
• Peptides to support elasticity and reduce breakage appearance.
• Omega 3-6-9 botanical complex to replenish natural lipids and shine.

Can I use it on every curl type and how often?

This serum is formulated for all curl patterns, from loose waves to tight coils. Frequency depends on hair porosity and needs: light daily applications work well for fine curls, while thicker or drier textures may benefit from targeted daily use or overnight treatments once or twice weekly. Start with a small amount and increase as necessary to avoid product buildup.

• Fine or low-porosity curls: small daily doses to prevent weighing down.
• Medium to coarse curls: apply more liberally to dry ends or before styling.
• Tight coils: use as a leave-in primer and occasional overnight restorative treatment.

Is this formula clean and cruelty-free?

The serum is free from silicones, parabens, sulfates, mineral oil, phthalates, petroleum, and gluten, and is both vegan and cruelty-free. That makes it a good fit for shoppers seeking cleaner, salon-backed curl care without common synthetic additives. Its scent and texture are designed to be lightweight and suitable for layered routines.

• Vegan and cruelty-free formulation.
• Excludes common harsh ingredients for gentler everyday use.
• Lightweight texture that layers well with other styling products.
