Olaplex Wash & Shine Fine Hair Kit — Nº. 4FINE & Nº.5FINE Shampoo + Conditioner + Scalp Treatment for Lightweight Volume & Strengt

This kit combines Olaplex's fine-hair formulations to gently cleanse, fortify fragile strands, and build visible lift without weighing hair down. It pairs a low-residue shampoo and a featherlight conditioner with a small scalp treatment so you can address root volume, mid-length strength, and scalp hydration in one short routine. The system focuses on improving hair resilience and appearance after daily styling, color services, or environmental stressors.

How does this kit create volume for fine hair?

The duo uses flexible polymers and a Hydra-Balancing Matrix to lift at the root while keeping lengths light and bouncy. Low molecular weight hyaluronic acid helps maintain softness without heavy buildup, so volume lasts all day without stiffness or tack.

• Flexible polymers provide root lift and body.
• Featherlight conditioning prevents flattening.
• Formulated to double visible volume instantly in clinical testing.

Can it strengthen and reduce breakage without weighing hair down?

Yes — Olaplex fine-hair formulas are designed to rebuild hair structure and protect against future damage while remaining lightweight. Clinical measures showed a significant reduction in breakage on treated, weakened hair, making the combination suitable for fragile or chemically treated strands.

• Active repair ingredients reduce breakage risk.
• Conditioner delivers moisture without heavy oils.
• Gentle cleansing removes residue that can stress fine hair.

What does the scalp sample do and how should I use it?

The included scalp treatment hydrates and soothes dry or tight scalps, supporting a healthier foundation for stronger hair. Use it as a targeted step before or after washing to calm irritation and add light moisture where the hair grows.

• Apply sparingly to the scalp; massage in for targeted hydration.
• Leaves the scalp soothed without oily residue.
• Works with the shampoo and conditioner for an integrated routine.

How quickly will I notice results and what can I expect?

Many users observe immediate lift and improved manageability after the first wash, with progressive strengthening and reduced breakage over repeated use. Expect fuller-looking roots, smoother mid-lengths, and a lighter feel compared with heavier volumizing systems.

• Instant boost in volume and body after one use.
• Ongoing use builds resilience against breakage.
• Maintains hydration while avoiding over-conditioning.

Who is this for: This kit suits people with fine, limp, or fragile hair looking for a non-heavy approach to volume and repair. It’s appropriate for chemically treated, heat-styled, or naturally straight, wavy, curly, and coily textures that need lift at the root, weightless conditioning along the lengths, and occasional scalp hydration. If you want salon-grade strengthening and fuller-looking hair without product buildup, this three-step set offers a compact, easy-to-use regimen.
