Neutrogena Hydro Boost Shampoo & Conditioner Set 2 x 12 fl oz — Hyaluronic Acid, Sulfate-Free Hydration for Dry Scalp

Neutrogena Healthy Scalp Hydro Boost Shampoo & Conditioner is a two-step hydrating hair set formulated with hyaluronic acid to cleanse, moisturize, and support a healthy scalp without harsh sulfates.

This shampoo and conditioner duo is built to replenish moisture in dry hair and scalp while staying gentle enough for everyday use. Each 12 fl oz bottle contains formulas that use hyaluronic acid — a moisture-attracting ingredient familiar from skincare — to help your hair retain hydration. Free from parabens, phthalates, and common sulfated surfactants, the pair is pH-balanced and safe for color-treated hair, making it a versatile option for many hair types.

How does this set hydrate dry hair and scalp?

The formulas include hyaluronic acid, which draws in and helps lock moisture into strands and the scalp. The shampoo cleans without stripping natural oils, while the conditioner smooths and restores softness. With regular use, hair looks less brittle and the scalp feels more comfortable.

• Hyaluronic acid attracts and retains moisture in hair fibers and scalp.
• Non-drying cleansing system removes buildup without harsh sulfates.
• Conditioner replenishes surface moisture and improves manageability.

Will this damage color-treated or chemically processed hair?

The set is formulated to be gentle and safe for color-treated hair; it avoids sulfated surfactants that can accelerate color fade. Its pH-balanced approach helps preserve color and minimizes roughing of the hair cuticle. Still, for very porous or freshly processed hair, follow stylist recommendations.

• Free of SLS and SLES to reduce aggressive stripping of color.
• pH-balanced formulas help protect color vibrancy.
• Suitable for most color-treated and chemically processed hair types.

How should I use the shampoo and conditioner together?

Start by massaging the shampoo into wet hair and scalp to lift oil and impurities, then rinse thoroughly. Apply the conditioner from mid-lengths to ends, leaving it on for one to two minutes before rinsing for best slip and hydration. Use both consistently to maintain the scalp’s natural barrier and keep strands moisturized.

• Use shampoo to cleanse and remove product buildup gently.
• Apply conditioner mainly to mid-lengths and ends to avoid weighing roots down.
• For optimal results, include in a regular hair-care routine with other Hydro Boost products.

What ingredients are NOT in these formulas and why does that matter?

These products are formulated without parabens, phthalates, SLS, SLES, and sulfated surfactants that can be drying or irritating for some scalps. Removing these components helps preserve natural oils and reduces the risk of over-drying, especially for sensitive or dry scalps. The result is a gentler experience that focuses on restoring moisture rather than stripping it away.

• No parabens or phthalates—fewer common preservatives and additives.
• No SLS/SLES or sulfated surfactants—cleaning without excess dryness.
• Gentle, non-medicated formulas suitable for frequent use.

Who is this for: This Hydraboost shampoo and conditioner pair is designed for people with dry hair or a dry scalp seeking a moisture-first routine. It also works well for straight, wavy, and curly hair types and anyone with color-treated or sensitized strands who wants a gentler daily cleanser and a replenishing conditioner. If you want to bring scalp care into a broader self-care routine, the set complements the rest of Neutrogena’s Hydro Boost line for body, hands, and face.
