Olaplex Wash & Shine Fine Hair Kit — No.4FINE & No.5FINE with No.0.5 scalp treatment, lightweight volumizing and strengthening

This kit pairs Olaplex's fine-hair No. 4FINE shampoo and No. 5FINE conditioner with a travel-size No. 0.5 scalp treatment to create an approachable daily regimen. Formulated to protect from breakage while providing lift at the roots, the products focus on repairing and preventing damage caused by mechanical styling, chemical services, and everyday exposure. Lightweight hydrating agents and volume-building polymers work together so fine textures gain body and manageability without excess residue.

How does this kit build volume without weighing hair down?

The formulas use flexible, lightweight polymers and a hydra-balancing matrix that lift strands at the root while avoiding heavy conditioning agents. Low molecular weight hyaluronic acid adds moisture without creating limpness, and the rinse-off texture keeps hair airy and bouncy.

• Flexible polymers provide root lift and long-lasting body
• Hydra-balancing matrix cleanses without over-conditioning
• Low molecular weight hyaluronic acid hydrates without weighing hair down
• Clinically demonstrated immediate volume boost

Will this routine help strengthen and reduce breakage?

Olaplex’s formulas focus on fortifying weakened bonds and reducing mechanical breakage from styling. Clinical testing on bleached hair showed a measurable reduction in breakage, and regular use supports stronger strands that resist everyday stressors.

• Formulated to repair and prevent future damage
• Clinically proven reduction in breakage on tested hair types
• Strengthening actives support resilience during styling

How should I use each product in the kit for best results?

Use No. 4FINE to gently cleanse and lift roots, follow with No. 5FINE to detangle and add lightweight moisture, and apply the sample scalp treatment as needed to soothe dryness or irritation. For visible benefits, incorporate the shampoo and conditioner into your regular wash routine; apply the scalp treatment to a dry or damp scalp based on sensitivity.

• Massage No. 4FINE into wet hair and rinse thoroughly
• Apply No. 5FINE mid-length to ends, comb through, then rinse
• Use No. 0.5 sample on scalp to hydrate and calm irritation as needed
• Combine with minimal heat styling to preserve volume and strength

Is this safe for chemically treated or color-treated fine hair?

The kit is formulated with ingredients that are compatible with color and chemical services and is suitable for strengthening fragile, processed strands. It is designed to support hair integrity after salon treatments while helping maintain lift and vibrancy.

• Supports color-treated and chemically processed hair
• Helps protect fragile fibers from further damage
• Lightweight hydration maintains color vibrancy without buildup
