Wella Professionals Ultimate Repair Leave-In Treatment 4.7 fl oz — AHA Repair, Thermal & UV Protection

Wella Professionals ULTIMATE REPAIR is a lightweight leave-in cream-serum that repairs damaged hair while delivering thermal, UV and anti-frizz protection for all hair types.

This delicate cream-serum blends repair and protection in a single leave-in treatment designed to smooth strands, reduce breakage and make styling easier. Formulated with Alpha-Hydroxy Acid (AHA) to strengthen hair from within, the product offers daily defense against heat tools, sun exposure and mechanical damage while keeping frizz under control for up to 72 hours. It’s paraben-free and dermatologically tested, suitable for straight, wavy, curly and textured hair that needs reinforcement and manageability.

How does this leave-in help damaged hair recover?

The formula targets internal hair structure using AHA to rebuild strength and improve elasticity. Over time, regular use helps reduce visible breakage and leaves hair feeling softer and more resilient without weighing it down.

• Alpha-Hydroxy Acid (AHA) to support internal fiber repair
• Light cream-serum texture penetrates without greasiness
• Visible reduction in split ends and breakage with continued use
• Safe for color-treated and chemically processed hair

Will it protect my hair from heat styling and sun damage?

Yes — the treatment provides thermal and UV protection to shield strands during heat styling and sun exposure. It forms a lightweight barrier that helps minimize mechanical damage from brushes and tools while defending color and moisture.

• Heat protection suitable for blow-drying and hot tools
• UV filters help reduce sun-related fading and dryness
• Protective film lowers friction from styling and brushing
• Ideal as a pre-styling step for everyday routines

How long does the anti-frizz effect last and how should I apply it?

The anti-frizz benefit can last up to 72 hours depending on hair type and environmental conditions. Apply a small amount to towel-dried or dry hair, focusing on mid-lengths to ends, then style as usual; a little goes a long way.

• Anti-frizz control for up to 72 hours
• Best used on damp hair for even distribution
• Can be re-applied sparingly to dry hair for touch-ups
• Helps define curls and reduce flyaways without crunch

Is this product suitable for all hair types and sensitive scalps?

The leave-in was developed for all textures — fine to coarse, straight to curly — and is dermatologically tested. It’s paraben-free and designed to deliver protection and repair without heavy residue, making it compatible with frequent use and many hair routines.

• Formulated for all hair types and textures
• Paraben-free; dermatologically tested for skin compatibility
• Non-greasy finish preserves volume on finer hair
• Supports curl definition and smoothness on textured hair
