Keratin smoothing, Olaplex bond repair, scalp therapy, and gloss treatments — restorative services designed to rebuild, protect, and elevate your hair at The Salon Project by Joel Warren.
Treatments are the most misunderstood category in the salon. Clients often confuse a keratin treatment with a chemical relaxer, a conditioning masque with a leave-in conditioner, and a gloss with permanent color. These are meaningfully different services with different mechanisms, different results, and different maintenance requirements. Understanding what each treatment actually does — and who it is appropriate for — is the foundation of a treatment recommendation at The Salon Project.
Joel Warren's approach to hair treatments is informed by his four decades of observation: every color service, every heat styling session, every harsh winter and humid summer takes something from the hair. Treatments are the salon's answer to that cumulative toll. They are not reactive luxury — they are proactive investment in the long-term quality of your hair.
We treat Midtown professionals who need their hair to perform reliably in all conditions, color clients who need their hair to remain structurally sound between lightening appointments, and clients whose hair has been significantly stressed and needs a disciplined, multi-session restorative protocol. In every case, the treatment plan is specific to your hair — not to a menu.
The keratin smoothing treatment is the most transformative service in our treatment menu — a multi-hour process that restructures the hair's surface using a keratin protein complex, sealing the cuticle and eliminating frizz at the source rather than at the surface. The result is hair that dries faster, moves more smoothly, and requires significantly less heat styling time each morning. At The Salon Project, we use only formaldehyde-free keratin formulas, making the service safe for color-treated hair and for clients sensitive to chemical processing. The effect builds gradually over the first 72 hours and peaks at two to three days post-treatment, lasting four to six months depending on your hair type and wash frequency.
A deep conditioning masque is the most straightforward investment in hair health available at the salon. Using professional-grade conditioning agents — heavier, more penetrative, and more targeted than anything available over the counter — this treatment saturates the hair shaft with moisture and protein in a ratio suited to your hair's specific needs. For color-treated hair, it replenishes what chemical processing has removed. For heat-damaged hair, it begins the slow work of rebuilding elasticity. For natural hair, it provides the sustained moisture that dry indoor air and winter weather consistently strip away. We do not use masques as a pro forma upsell; we recommend them specifically when your hair's condition warrants it.
Healthy hair begins at the scalp — a truth that the hair industry acknowledged late and has only recently begun to address with the sophistication it deserves. Our scalp therapy service is a multi-step protocol that combines exfoliation (removing the buildup of product, sebum, and dead skin cells that congests follicles), a targeted serum application, and a pressure-point scalp massage that stimulates circulation and supports the conditions under which healthy hair grows. It is not a luxury add-on. For clients experiencing thinning, hair loss, or persistent scalp irritation, it is a meaningful clinical intervention.
Olaplex's chemistry is specific and well-documented: the active ingredient bis-aminopropyl diglycol dimaleate locates and reconnects broken disulfide bonds inside the hair cortex — the bonds that give hair its tensile strength and resistance to breakage. This is not a moisturizing treatment; it is a structural one. It is appropriate for hair that has been lightened, chemically straightened, or repeatedly heat-styled to the point where elasticity has been compromised. The standalone Olaplex treatment — using the No.1 Bond Multiplier and No.2 Bond Perfector in sequence — is one of the most evidence-based treatments we offer, and the results are most visible in hair that has experienced significant chemical stress.
A gloss is the fastest service in the treatment menu and one of the most immediately gratifying. In thirty to forty-five minutes, a demi-permanent gloss seals the hair's cuticle, deposits a sheer veil of tone (or simply enhances the existing color), and multiplies the reflectivity of the hair surface by a factor that is visible in almost any light. The gloss washes out gradually over four to six weeks, which makes it an ideal service for clients who want a periodic refresh without the commitment of permanent color. It is also the most effective treatment for eliminating the flat, muted appearance of color that has faded between appointments.
Co-founder of the legendary Warren-Tricomi salons, Joel Warren has spent four decades shaping the hair of fashion's most influential figures — from editorial runways to Hollywood red carpets. His philosophy informs every service at 45 Rockefeller Plaza.
We are not a chain. We are one meticulously curated salon at the heart of Midtown Manhattan, where every appointment receives our full attention. Third Floor, 45 Rockefeller Plaza — steps from 30 Rock, Radio City, and Saks Fifth Avenue.
Every member of our team is personally vetted and continually trained. Our colorists are among the most sought-after in New York; our stylists have dressed hair for editorial shoots, Fashion Week presentations, and Broadway opening nights.
We believe that beautiful hair and healthy hair are the same thing. Every service — from the first consultation through aftercare — is designed to strengthen, protect, and elevate the integrity of your hair, never to compromise it.
Before any treatment is selected, your stylist assesses the condition of your hair and scalp: its porosity, protein-moisture balance, level of chemical processing, and any specific concerns (thinning, frizz, dryness, damage). The treatment is selected based on this assessment, not on a menu default.
Most treatment services begin with a clarifying shampoo that removes buildup and opens the cuticle, allowing treatment ingredients to penetrate effectively. This step is particularly important for clients who use heavy styling products or live in areas with hard water.
The treatment is applied with precision to ensure even coverage. For keratin, this involves careful sectioning and thorough saturation. For masques and Olaplex, the formula is distributed through the hair and processed under heat to maximize penetration.
Processing time varies by treatment. Keratin is sealed with a flat iron at a precise temperature; Olaplex processes at room temperature; masques are often processed under a hooded dryer to open the cuticle and drive conditioning agents deeper.
Every treatment service ends with a specific aftercare protocol. For keratin, this includes instructions for the critical 72-hour window after the service. For Olaplex and masques, it includes product recommendations that extend the results between salon visits.
New York presents specific challenges for hair health that our treatment menu is directly designed to address. The dry, recirculated air of Midtown office buildings — particularly in winter — strips moisture from even the healthiest hair. The hard water variation across buildings affects how color holds and how the scalp behaves. The humidity of a New York August works directly against the frizz management that keratin and smoothing treatments provide. The Hamptons summer — salt water, sun, and repeated rinsing — can undo months of color work and structural integrity in a matter of weeks.
Our Midtown location at 45 Rockefeller Plaza is convenient for professionals in the NBC, Comcast, Deloitte, and Lazard offices in the surrounding complex, for guests of The Peninsula and the JW Marriott Essex House who are in New York for extended stays, and for UWS and UES clients who use the express B/D/F/M service to 47–50 Sts–Rockefeller Center. Treatment appointments, particularly keratin and Olaplex, can be scheduled in the early morning before the workday begins or in the early evening — we work around the Midtown schedule.
The treatment category suffers from significant marketing confusion. The same word — "treatment" — is used to describe everything from a thirty-second rinse-out conditioner to a four-hour keratin service that structurally alters the hair's surface. Here is what each major treatment type actually does at the level of the hair's anatomy.
Each strand of hair has three layers: the medulla (the innermost core, present mainly in coarser hair types), the cortex (the middle layer, which contains the hair's melanin pigment and disulfide bonds that determine strength and curl pattern), and the cuticle (the outermost layer, composed of overlapping scales that protect the cortex and determine smoothness and shine). Most treatments work primarily on the cuticle and the cortex. Understanding which layer a treatment addresses tells you what result to expect.
Keratin treatments work on the cuticle. The keratin protein complex coats and seals the cuticle scales, which are normally rough and slightly open — the source of frizz and dullness. By sealing these scales flat, a keratin treatment creates a smoother hair surface that repels humidity, dries faster, and reflects light more uniformly. It does not change the internal structure of the hair. It is a surface intervention with a semi-permanent but reversible effect. Formaldehyde-free formulas — the only kind we use at The Salon Project — are safe for color-treated hair and produce results that are somewhat softer and more natural-looking than formaldehyde-based versions.
Olaplex works on the cortex. Specifically, it targets disulfide bonds — the cross-links between the hair's protein chains that give hair its tensile strength and resistance to breakage. Chemical processing (lightening, perming, relaxing) breaks these bonds. Olaplex's active ingredient (bis-aminopropyl diglycol dimaleate) identifies and reconnects broken bonds, restoring structural integrity at the molecular level. This is not a cosmetic improvement — it is a genuine structural repair. It is appropriate for hair that is breaking, stretching excessively when wet, or losing its elasticity. Hair that is merely dry or dull is better served by a conditioning treatment.
A professional deep conditioning masque works at the cuticle level, infusing the hair with moisture, emollients, and proteins that soften, strengthen, and add sheen to the exterior of the shaft. The distinction between a professional masque and an over-the-counter conditioner is concentration and molecular weight: professional formulas use higher concentrations of active ingredients and smaller molecular weights that penetrate more deeply, particularly when processed under heat. For color-treated, dry, or coarse hair, a monthly masque is one of the most effective maintenance tools available.
The Midtown professional faces a specific set of environmental challenges that are worth addressing directly. Indoor heating in winter — particularly in older Rockefeller Center and Park Avenue office buildings — produces extremely dry air that depletes moisture from the cuticle at an accelerated rate. A humidifier in the bedroom and a weekly masque mitigate this significantly. In summer, the interplay of humidity (which swells the cuticle) and air conditioning (which rapidly removes moisture) creates a cycle of expansion and contraction that accelerates frizz and breakage. A smoothing treatment applied before Memorial Day and refreshed in September creates a season-long defense.
For clients with beach or Hamptons summers: chlorine and salt water are both significant stressors. Pre-swim saturation with fresh water slows absorption of pool or ocean water. A clarifying treatment at the start of the summer and again at its end removes accumulated mineral deposits and positions the hair for whatever service comes next.
Hair treatments work best in a coordinated service plan. A color appointment followed by a deep conditioning masque produces more luminous, longer-lasting results than color alone. A keratin treatment applied after a precision cut seals the ends and maximizes the impact of both services. Our treatment menu is designed to integrate with, not compete with, the other services we offer.
A keratin treatment coats and seals the hair's outer cuticle using a protein complex, reducing frizz and increasing smoothness without altering the hair's internal structure. The effect is semi-permanent and fades over time. A relaxer uses a chemical process to permanently break and reform the hair's disulfide bonds, straightening the hair at a structural level. Keratin treatments are reversible; relaxers are not.
Yes, provided the keratin formula is formaldehyde-free, which is what we use at The Salon Project. We recommend waiting at least two weeks after a color service before applying keratin, and we advise against booking color within two weeks after keratin. Your colorist will sequence your services appropriately.
Four to six months, depending on your hair type, how frequently you shampoo, and whether you use sulfate-free products (which extend the life of the treatment). Coarser, more resistant hair types may see results closer to four months; finer, less resistant hair can maintain results for up to six.
Olaplex repairs the hair's internal structure by reconnecting broken disulfide bonds in the cortex. A conditioning treatment works on the hair's exterior — adding moisture, softness, and shine to the cuticle layer. Both have value, but they address different problems. Olaplex is appropriate for structurally compromised hair (bleached, chemically processed, heat-damaged). A conditioning masque is appropriate for hair that is dry or lacks suppleness but is not structurally damaged.
For color-treated hair, once per month is a reasonable cadence. For very dry, coarse, or heavily processed hair, every three to four weeks. Your stylist will recommend a frequency based on your hair's specific condition.
Our scalp therapy service addresses the scalp conditions — buildup, poor circulation, follicle congestion — that can contribute to hair thinning. It is not a medical treatment for pattern baldness or alopecia, and we are transparent about this. For clients experiencing significant hair loss, we recommend consulting a dermatologist or trichologist in addition to receiving scalp therapy.
Use a sulfate-free shampoo — sulfates accelerate the dissolution of the keratin coating. Avoid chlorinated pool water without a cap. Limit salt water exposure. When heat styling, use a lower temperature than you might otherwise, as the hair is smoother and requires less heat to style. These habits can extend your treatment from four months to six.
45 Rockefeller Plaza, 3rd Floor, New York, NY 10111. The 47–50 Sts–Rockefeller Center station serves the B, D, F, and M lines and is steps from our entrance on Rockefeller Plaza.
Yes. Our treatment menu is designed to address the full spectrum of hair types and conditions, from fine and straight to coarse and tightly coiled. Every treatment begins with an assessment that informs the specific formula, application technique, and processing time appropriate for your hair.
We typically do not recommend combining keratin with same-day color or gloss, as the keratin seal can affect how subsequent products penetrate. Your colorist will sequence these services appropriately, often recommending the gloss two weeks after the keratin when the treatment has fully set.
