Olaplex Wash & Shine Fine Hair Kit — Nº.4FINE & Nº.5FINE + Nº.0.5 Scalp Sample | Lightweight Volume & Strength

Olaplex Wash & Shine Fine Hair Kit is a lightweight shampoo and conditioner duo with a scalp treatment sample designed to add instant volume, strengthen fragile strands, and hydrate without weighing fine hair down.

This kit combines Olaplex Nº.4FINE and Nº.5FINE with a small Nº.0.5 Scalp Treatment to create a simple, salon-grade regimen for fine, fragile, or chemically treated hair. The formulas use lower-molecular-weight hydrators and flexible polymers to lift at the roots, reduce breakage, and keep hair feeling clean and airy while supporting long-term strength. It's tailored to deliver body and resilience without heavy conditioning buildup.

How will this kit affect my fine hair's volume and body?

The shampoo and conditioner are formulated to build lift and maintain shape from root to tip without flattening fine strands. Flexible polymers create root lift and hold, while the lightweight conditioning system detangles and smooths without excess weight. You should notice fuller-looking hair immediately and improved body with continued use.

• Clinically tested to double hair volume instantly and throughout the day
• Flexible polymers add lift at the root for visible body
• Hydra-Balancing Matrix prevents over-conditioning while hydrating

Will this routine help strengthen and reduce breakage?

Olaplex focuses on repairing and strengthening strand integrity with ingredients that reduce breakage and support resilience. The system is clinically shown to lower breakage on damaged hair and is designed to rebuild strength over time when used consistently. It’s suitable for repeated styling and color-treated hair that needs reinforcement.

• Clinically proven to reduce breakage on bleached hair by about 60%*
• Formulation targets weak points to improve tensile strength
• Helps prevent future damage related to mechanical and chemical styling

Does the kit hydrate without weighing hair down or irritating the scalp?

The formulas use Low Molecular Weight Hyaluronic Acid and a Hydra-Balancing Matrix to deliver moisture that fine hair can accept without heaviness. The included Nº.0.5 Scalp Treatment sample provides targeted hydration and soothing for dry or reactive scalps. Together they aim to keep hair and scalp comfortable, clean, and touchable.

• Low Molecular Weight Hyaluronic Acid promotes soft, hydrated hair
• Hydra-Balancing Matrix keeps moisture balanced for fine textures
• Scalp Treatment sample hydrates and soothes without residue

How simple is this routine for daily use and styling?

The kit is built for easy incorporation into a daily or weekly regimen: cleanse, condition, and apply the small scalp treatment as needed. Both shampoo and conditioner are light-rinsing, helping styling products perform as intended while offering protection. Results are meant to be noticeable after a single use and improve with ongoing use.

• Quick shampoo and rinse that removes buildup, ready for styling
• Conditioner detangles quickly and supports styling volume
• Travel-size scalp treatment for targeted boost between washes

Who is this for: This kit is ideal for people with fine, limp, or fragile hair seeking lightweight hydration, visible volume, and improved strength—whether hair is natural, heat-styled, colored, or chemically processed. It’s especially useful for anyone wanting a straightforward, low-residue routine that supports scalp comfort and longer-term hair integrity.
