The Ordinary The Hair & Scalp Collection is a high-performance, clinically-curated multi-step regimen meticulously engineered to provide a comprehensive intervention for the structural health of the scalp and the visible density of the hair. In the science of advanced trichology, the health of the hair fiber is inextricably linked to the physiological state of the scalp—the biological "soil" from which the hair grows. This foundational collection brings together two of The Ordinary's most strategic follicular formulations: the Multi-Peptide Serum for Hair Density and the Natural Moisturizing Factors + HA (for Scalp). The regimen functions by utilizing multiple molecular pathways to repair, protect, and enhance the skin's architectural integrity and the hair follicle's productivity. The Hair Density Serum utilizes a sophisticated blend of REDENSYL™, CAPIXYL™, and Procapil™ to target the hair follicle's stem cells and improve the anchoring of the hair, leading to a look of increased volume and vitality. The NMF + HA Scalp Treatment functions as a biomimetic moisture seal, replenishing the natural moisturizing factors of the scalp's stratum corneum to prevent the dryness, flaking, and "tightness" that can stall healthy hair growth. The result is a scalp environment that feels measurably more comfortable and hydrated, complemented by hair that reflects a lush, polished density. Whether you are addressing localized thinning or seeking a proactive clinical routine for long-term scalp health, this collection provides the scientific foundation for a revitalized US appearance. Available for fast US delivery at theordinaryusa.co.
In the United States, the hair and scalp are subject to a staggering variety of regional environmental pressures and high-intensity lifestyle stressors that can rapidly deplete the skin's moisture reservoir and compromise hair density. For American consumers living in high-stress urban hubs like New York City, Chicago, or Los Angeles, the daily exposure to urban pollution, hard water minerals, and environmental particulate matter leads to "Scalp Fatigue"—characterized by chronic inflammation, product buildup, and a lackluster hair tone. Conversely, in the arid desert heat of the Southwest or the moisture-sapping winters of the Northeast, the scalp can become severely parched, leading to a compromised barrier and brittle hair. The Ordinary The Hair & Scalp Collection is a US essential because it provides a "smart" biological bridge for these diverse conditions. Its weightless, non-greasy format is perfectly suited for the fast-paced American lifestyle, offering a complete professional scalp routine that integrates seamlessly into nightly recovery rituals without pilling or leaving a residue on US bedding. It meets the sophisticated demand in the USA for high-tech "Clean Beauty" and "Scalp-First" hair care that prioritizes molecular transparency and clinical health, incorporating bio-tech molecules and skin-identical lipids to ensure that American users can achieve professional-grade results with maximum comfort. Whether you are navigating a long-haul transcontinental flight or seeking a repair step after a day of US sports, this collection provides the resilient hydration and density infrastructure needed to keep your hair looking polished and protected in any regional environment, across all 50 states.

The core science of the density step centers on a Multi-Peptide Complex. In clinical trichology, peptides like REDENSYL™ and CAPIXYL™ are recognized for their role in signaling the dermal papilla cells of the hair follicle. REDENSYL™ targets the stem cells to reactivate the growth phase, while CAPIXYL™ (a biomimetic peptide combined with Red Clover extract) helps to improve the anchoring of the hair and reduce the inflammation that can lead to thinning. For the US consumer, this translates to a more resilient hair foundation and a visible reduction in the look of sparse areas.
The scalp care step utilizes a complex of Amino Acids, Ceramides, and Hyaluronic Acid. The science behind these ingredients involves their status as fundamental building blocks of the skin's Natural Moisturizing Factors (NMF). By replenishing these vital molecules on the scalp, the treatment ensures that the barrier is physically repaired and shielded against the "alkaline shock" common with hard water in many US regions. This ensure that the US consumer's scalp remains hydrated, providing the ideal biological base for hair vitality.
To further support hair longevity, the formula includes **Procapil™** and **Baicapil™**. The science of Procapil™ involves its ability to target the main causes of alopecia: poor scalp micro-circulation and follicle aging. Baicapil™ functions by increasing cellular energy and protecting the follicles from oxidative stress. This ensures that the US consumer maintains a refreshed and youthful hair appearance, even under the pressure of a high-intensity American lifestyle.

To maximize the density and scalp-balancing results of this advanced duo, follow these professional application protocols:
- Preparation: Start with a clean, towel-dried or dry scalp. While these serums can be used on wet hair, they are designed for maximum absorption on a clean surface.
- Step 1 (Density Serum): In the evening (PM), apply a few drops of the Multi-Peptide Serum for Hair Density directly to the scalp. Massage thoroughly using circular motions, focusing on areas of concern (like the hairline or crown). Do not rinse.
- Step 2 (Scalp Hydration): Apply the Natural Moisturizing Factors + HA (for Scalp) to the scalp, either after the density serum or at a separate time of day (AM/PM). Massage gently until the light, milky solution is absorbed.
- Timing: Consistency is vital for hair and scalp health. Follow the regimen daily for at least 3-6 months to see significant structural changes in hair density and scalp comfort.
- Washing: There is no need to wash your hair immediately after application. The formulations are designed to be weightless and invisible.
- Sun Care: If you have thinning hair, remember that the scalp is more exposed to UV. Always protect your scalp with a US-approved mineral sunscreen or a hat when outdoors.
Note: Patch test before first use. Apply only to unbroken skin as directed. Keep out of reach of children.

What does The Ordinary The Hair & Scalp Collection do?
It provides a complete 2-step clinical regimen to improve the look of hair density with advanced peptides and rebalance the scalp barrier with skin-identical lipids and Hyaluronic Acid.
Will the density serum make my hair look greasy?
No. The formula is a water-based, oil-free serum designed to absorb instantly. When massaged in correctly, it leaves no oily residue or weight on the hair fibers.
How long will it take to see results?
Scalp hydration and comfort results are often visible within days. For a significant reduction in the look of thinning and improved density, consistent use over 3-6 months is typically required.
Can I use it on color-treated hair?
Yes. Both formulations are safe for color-treated and chemically-processed hair. In fact, the NMF for Scalp is excellent for soothing the scalp after a color service.
Is it safe for use during pregnancy?
Yes, the peptides, vitamins, and lipids in this collection are generally considered safe for use during pregnancy. However, we always suggest consulting your US physician before starting new active treatments.
Can I use it with my regular shampoo?
Absolutely. This collection is a leave-on treatment duo that should be used after your regular cleansing routine. For best results, use a non-stripping cleanser like the Sulphate 4% Cleanser.
What is REDENSYL™?
It is a patented clinical active that targets the hair follicles' stem cells and dermal papilla fibroblasts to support the appearance of hair density and volume.
Does it have a clinical scent?
The products are 100% fragrance-free. Any faint clinical aroma is the natural result of the high-purity active peptide and botanical ingredients.
How long will the set typically last?
With daily use, the collection typically lasts between 2 and 3 months, providing exceptional clinical value for the US market.
Can I apply it in the morning?
Yes, though many US users prefer nighttime application to allow the serums to work during the body's natural repair cycle without the interference of styling products.
Is it non-comedogenic?
Yes. Both serums in the collection are specifically formulated to be non-comedogenic and will not clog pores on the scalp.
Can I use it if I have dandruff?
While not a medicated anti-dandruff treatment, the NMF for Scalp helps to manage the dryness-induced flaking that is often mistaken for dandruff in arid US climates.
Is it sustainably sourced?
Yes, the plant-derived components and peptides used in this formula are sourced through sustainable methods that meet high US and international standards.
Where should I store the set?
Store in a cool, dry place away from direct US sunlight. Ensure all caps are tightly closed to maintain the clinical stability of the actives.
Can I use styling products over the serums?
