Neutrogena Hydro Boost Shampoo & Conditioner Set - 2 x 12 fl oz Hyaluronic Acid Hydrating Duo for Dry Scalp & Color-Treated Hair

Neutrogena Healthy Scalp Hydro Boost Shampoo & Conditioner Set is a two-step, hyaluronic acid–infused system that cleanses and delivers lasting hydration to dry scalp and hair without harsh sulfates.

This paired shampoo and conditioner are formulated to refresh and replenish moisture to dehydrated hair and scalp while remaining gentle enough for daily use and safe on color-treated strands. Each 12 fl. oz. bottle uses hyaluronic acid, a skin-friendly humectant, to attract and retain moisture, helping the scalp’s natural barrier stay balanced. The formulas are non-medicated, pH balanced, and free from parabens, phthalates, SLS, SLES, and sulfated surfactants, making the set suitable for a wide range of hair types including straight, wavy, and curly.

How does this set hydrate dry scalp without feeling heavy?

The Hydro Boost duo relies on hyaluronic acid to draw moisture into the scalp and hair fibers rather than coating them with heavy oils. Lightweight conditioning agents smooth the cuticle and lock in hydration so hair feels softer, not weighed down. The result is manageability with a hydrated finish rather than grease.

• Hyaluronic acid attracts and retains moisture at the scalp and hair surface
• Gentle surfactants cleanse without stripping natural oils
• Lightweight conditioners smooth cuticles for softer, non-greasy hair
• pH balanced to support the scalp’s natural barrier

Will this damage color-treated or chemically processed hair?

This shampoo and conditioner are formulated to be safe for color-treated hair. They avoid sulfated surfactants that can accelerate color fade and include conditioning ingredients to help preserve shine and manageability in chemically treated strands.

• Free of SLS and SLES, which can strip color
• Conditioning formula helps maintain smooth, shiny hair
• Designed for daily or regular use without overly harsh ingredients

How should I use the Hydro Boost Shampoo & Conditioner for best results?

Use the shampoo to cleanse the scalp and hair, rinsing thoroughly, then follow with the conditioner focusing on mid-lengths to ends. For scalp hydration, gently massage the conditioner into the scalp if you prefer; otherwise concentrate on lengths to avoid buildup. Pairing the two products consistently gives the most noticeable improvement in moisture retention.

• Wet hair thoroughly and apply shampoo to the scalp, lather, and rinse
• Apply conditioner from mid-lengths to ends, leave for 1–2 minutes, then rinse
• For extra scalp hydration, gently massage conditioner into the scalp occasionally
• Use regularly and combine with other Hydro Boost products for full-body hydration

What ingredients are intentionally excluded and why does that matter?

The formulas omit parabens, phthalates, and sulfated surfactants like SLS and SLES to reduce the risk of irritation and avoid aggressive stripping of natural oils. This cleaner ingredient profile supports a balanced scalp environment while delivering hydration with fewer potential irritants.

• No parabens or phthalates—fewer controversial preservatives
• No SLS or SLES—milder cleansing that protects color and moisture
• Non-medicated—designed for regular scalp care rather than treating scalp conditions

Who is this for: This set is aimed at anyone experiencing dryness in the hair or scalp who wants a gentle, hydrating daily routine—especially people with dry or dehydrated hair, those who color or chemically treat their hair, and anyone seeking a milder, moisture-focused alternative to sulfate-heavy shampoos. It also suits users who prefer products with a simplified ingredient profile and who may already use other Hydro Boost items in their body and face care regimen.
