Hair is made up of protein. Every touch, every treatment, every style you love—it all rewrites your hair’s protein. When protein is damaged, hair’s look and feel are compromised. That’s why Nexxus uses protein science not just to repair hair but to restore its ability to perform. It isn't about one perfect hair day. It's about a lifetime of healthy hair, built strand by strand. Healthy, moisturized hair isn’t just about hydration – it’s about balance. When your hair’s protein-lipid ratio is off, strands become stiff, brittle, dry, and frizzy because the internal structure breaks down and the outer cuticle can’t hold moisture. THERAPPE and HUMECTRESS, our ultimate moisture collection, uses POLYSOFT HYDRATOR technology with tri-lipids and protein-strengthening actives to restore that balance. It seals the cuticle to lock in hydration visibly combats dryness in just one use. Our best-seller shampoo and conditioner also deliver a moisture boost for softness and manageability, detangles hair and reduces frizz for polished strands. The shampoo for dry hair and the conditioner for dry hair helps rebuild your hair’s structure and lock in moisture, so hair feels soft, smooth, and resilient—no matter your texture. Nexxus, the protein science behind powerful hair since 1979.

Frequently Asked Questions
What makes this shampoo a premium choice over drugstore brands?
Therappe is built on Nexxus's protein-science heritage since 1979 and uses 4.9% Polysoft Hydrator with a tri-lipid blend, offering salon-level performance that mass-market shampoos rarely match.
Does the 13.5 oz salon-style bottle feel high-end on a vanity?
Yes. The 13.5 oz bottle is part of Nexxus's professional salon presentation, designed to look elegant on a bathroom vanity, shower caddy, or guest bathroom shelf.
Is the visible softness result comparable to an in-salon treatment?
98% of consumers validated visible softness, and the formula is engineered to repair dryness in a single wash, making it a strong at-home alternative to a salon conditioning service.
Does the heritage brand status justify the price point?
Yes. Nexxus has been a trusted salon brand for decades, and Therappe's protein-lipid science gives it a credibility premium over newer or generic competitors.
Will the cuticle-sealing formula give my hair a glossy, finished look?
Yes. The cuticle-sealing technology smooths the hair surface, reducing frizz and producing a polished, light-reflective shine associated with luxury haircare.
Is this a worthy upgrade from my current premium shampoo?
If you are seeking deep hydration plus protein-lipid repair in one step, Therappe offers a more complete regimen than many premium shampoos that only moisturize or only strengthen.
Does this bottle look impressive enough to keep displayed in a luxury bathroom?
Yes. Its clean, professional 13.5 oz salon-style packaging is designed to look intentional and elevated, even in a curated, high-end bathroom.
Is this the kind of shampoo I'd expect to find at a high-end salon?
Yes. Nexxus is widely used in professional salons, and Therappe is one of its flagship moisture products, making it a true salon-quality option for home use.
Will the protein-strengthening actives feel heavy on fine, expensive hair?
No. The Polysoft Hydrator technology is formulated to deliver strength without weighing hair down, preserving bounce and airy movement.
Does this qualify as a prestige-tier haircare purchase?
Yes. Backed by Nexxus's heritage science, best-seller status, and clinical-style validation, Therappe sits firmly in the prestige haircare tier.
How does this compare to a luxury department store shampoo at double the price?
Therappe delivers comparable 72-hour hydration, protein-lipid repair, and salon-level results through its Polysoft Hydrator technology, often at a more accessible prestige price point.
Is this better than a luxury oil-based shampoo for dry hair?
It depends on your priority, but Therappe's tri-lipid blend offers targeted lipid replenishment and cuticle sealing, often outperforming single-oil formulas for sustained moisture.
How does it compare to a salon-exclusive professional shampoo I can only buy at a salon?
Therappe gives you similar salon-grade hydration and protein science in a format available for everyday home use, without requiring a salon visit to restock.
Is the unscented formula less luxurious than a perfumed option?
Not at all. The unscented profile is a deliberate luxury choice for fragrance-sensitive users and those who prefer to layer their own signature scents.
Will a 13.5 oz bottle feel small for a luxury product?
No. 13.5 oz is the salon-standard size for Nexxus Therappe, designed to deliver weeks of daily hydration per bottle and pair seamlessly with the matching conditioner.
Does the best-seller status really matter for a luxury purchase?
Yes. Best-seller status signals consistent customer validation, which is an important trust signal when investing in premium haircare.
How do I use Nexxus Therappe Shampoo for the best results?
Apply to wet hair, massage into the scalp and strands to build a gentle lather, then rinse thoroughly. For optimal hydration, follow with the Nexxus Therappe Conditioner and allow it to sit for 1–2 minutes before rinsing.
How often should I use this shampoo on dry or chemically treated hair?
Therappe is gentle enough for daily use, but most users with dry or chemically treated hair see excellent results washing 2–3 times per week to maximize the 72-hour moisture benefit.
Do I need to use the matching Therappe conditioner with this shampoo?
While the shampoo works well on its own, the matching Therappe conditioner is designed to complement its 72-hour hydration system and is recommended for the best softness, detangling, and frizz-control results.
Is this shampoo compatible with color-treated, keratin-treated, or chemically relaxed hair?
Yes. Therappe is suitable for chemically treated and color-processed hair, and its gentle, unscented formula supports color longevity and strand repair.
Can I use this shampoo alongside other haircare products like serums or leave-in treatments?
Yes. Therappe is compatible with most serums, leave-in conditioners, and styling products. Apply Therappe first to cleanse, then layer your preferred post-wash treatments on damp hair.
What is included when I order this product, and is anything sold separately?
You will receive one 13.5 oz bottle of Nexxus Therappe Ultimate Moisture Shampoo. The matching Therappe Conditioner, scalp treatments, and other Nexxus products are sold separately.
Is this shampoo safe for sensitive scalps and fragrance-allergy users?
Yes. The unscented, gentle formulation is designed for fragrance-sensitive users, allergy-prone scalps, and those who prefer to layer their own signature scents without competition.
Will this shampoo dry out my hair with regular use?
No. Therappe is specifically engineered to add and retain moisture through its 4.9% Polysoft Hydrator and tri-lipid blend, helping prevent the dryness often associated with regular cleansing.
What is the difference between a hydrating shampoo and a regular shampoo?
A regular shampoo focuses primarily on cleansing, while a hydrating shampoo like Therappe is formulated to cleanse and simultaneously restore moisture, smoothness, and the hair's protein-lipid balance, making it ideal for dry, frizzy, or chemically treated hair.
