Neutrogena Hydro Boost Shampoo & Conditioner Set — 2 x 12 fl oz Hydrating Hyaluronic Acid

Neutrogena Healthy Scalp Hydro Boost Shampoo and Conditioner is a two-step hydrating hair set infused with hyaluronic acid to replenish moisture for dry scalp and dry hair.

This shampoo and conditioner duo is formulated to hydrate and support the scalp’s natural barrier while cleansing and smoothing strands. Each 12 fl oz bottle contains a gentle, non-medicated formula with hyaluronic acid — a humectant that helps attract and retain moisture — and is free from parabens, phthalates, SLS, SLES, and other sulfated surfactants. The pair is pH-balanced and safe for color-treated hair, designed to fit into a simple, everyday routine and to pair easily with other Hydro Boost body and facial products.

How does this set help when my scalp feels dry and tight?

The formulas target scalp dryness by delivering humectant-rich hydration that helps reduce surface tightness without leaving residue. Regular use supports the scalp’s moisture balance and avoids the stripping sensation some cleansers cause.

• Hyaluronic acid attracts and holds moisture at the scalp surface.
• Gentle surfactants cleanse without over-drying.
• pH-balanced to help maintain the scalp’s natural barrier.

Will this work on color-treated, curly, or fine hair?

The set is suitable for a wide range of hair types — from straight to curly and fine to coarse — and it’s formulated to be safe for color-treated hair. It aims to add hydration and manageability without weighing strands down or altering color vibrancy.

• Non-drying formula that supports different textures.
• Safe for color-treated hair to help preserve tone and shine.
• Lightweight conditioning to avoid heavy buildup on fine hair.

How should I use the shampoo and conditioner together for best results?

Use the shampoo to cleanse and follow with the conditioner to lock in moisture and soften hair cuticles. For optimal hydration, apply to wet hair, lather the shampoo, rinse thoroughly, then distribute conditioner from mid-length to ends and rinse after a short wait.

• Apply shampoo to wet hair, work into a gentle lather, then rinse completely.
• Apply conditioner mainly to mid-lengths and ends; leave 1–2 minutes for hydration.
• Use consistently as part of a routine and combine with other Hydro Boost products for added skin and hair hydration.

What’s in the formulas and what’s left out?

Both bottles center on hydrating ingredients like hyaluronic acid and are formulated to be gentle on scalp and hair. They intentionally exclude common harsh additives and sulfated surfactants to reduce irritation and dryness risk.

• Includes hyaluronic acid to attract and retain moisture.
• Free from parabens, phthalates, SLS, SLES, and sulfated surfactants.
• Gentle, non-medicated formulations suitable for regular use.

Who is this for: This Neutrogena Healthy Scalp Hydro Boost Shampoo & Conditioner set is designed for anyone with dry scalp or dry hair seeking a gentle, hydration-focused daily cleanse and condition. It’s a solid choice for those with color-treated hair, people who prefer formulas without common harsh additives, and shoppers looking to pair their haircare with the Hydro Boost line for a cohesive moisturizing routine.
