Introduction

In the often noisy world of professional hair dryers, the Valera Swiss Silent Jet 8700 Professional Hair Dryer presents itself as a distinct proposition. Its name announces it clearly: "Silent Jet". This is not a simple marketing claim, but the central pillar of its identity. Designed in Switzerland for demanding professional use and for discerning private users, this 2400W hair dryer promises a marriage between undeniable drying power and remarkable acoustic discretion. But beyond the noise – or rather, its absence – what does it truly bring to hair health and daily practicality? We dissect its specifications, its technologies, and the concrete feedback from the community to evaluate whether this tool delivers on its promises for fine, thick, curly, or coily hair.

Strengths and Weaknesses

Before going into detail, here is a summary of the perceived strengths and limitations of the Valera Swiss Silent Jet 8700.

Strengths

Reduced Sound Level: Its most praised feature. At approximately 66 dB(A), it is considerably quieter than most professional hair dryers.
Fast and Effective Drying: The Smart Airflow technology and AC Performance motor generate a powerful and optimized airflow for accelerated drying.
Notable Ease of Use: Lightweight (580g), with an ergonomic grip and a 3-meter anti-twist SuperFlex cable (Rotocord), it reduces fatigue during use.
Cold "Touch Me" Nozzle: A secure accessory that remains cool to the touch even after prolonged use, allowing for precise manipulation without risk of burns.
Integrated Protection System: The Backstop system prevents hair from being sucked into the intake grill, a major safety asset.

Weaknesses

The Silence is Relative: While testers agree on its discretion, some users note that it is not "silent" in an absolute sense, but significantly less noisy than a conventional appliance.
Perceived Value for Money: For a minority of users, the perceived value may be questioned, believing the performance does not fully justify the investment compared to entry-level models.
Basic Accessories: It is supplied with a diffuser and two concentrator nozzles, but some might regret the absence of more specialized accessories (like a round brush).

Technologies and Impact on the Hair Fiber

The Valera Swiss Silent Jet 8700 relies on a technological mix focused on efficiency and preserving hair health.

Ionic Technology: The appliance integrates an ion generator. The principle is known: the emitted negative ions break water molecules for faster penetration into the fiber, allowing for reduced exposure to heat. The promised result is hair that is less dehydrated, more shiny, and with less static electricity. For fine and flat hair, this can help avoid the "frizzy electricity" effect. For thick, curly, or coily hair, this aid in moisture retention is precious for drying that does not excessively dry out the cuticle.
AC Performance Motor and Smart Airflow: Unlike many consumer models equipped with less powerful DC motors, the AC motor is the professional standard for its power and longevity (advertised up to 2000 hours). Coupled with the Smart Airflow optimization, it generates a concentrated and powerful airflow. This is what enables the "up to 35% faster drying" touted by the manufacturer. Fast drying is a major asset for hair health: less time under heat means less thermal stress, less risk of keratin denaturation, and therefore better preservation of natural strength and elasticity.
Coating and Construction: The technical data indicates a main body made of professional-grade durable plastic. The absence of specific mention of ceramic or tourmaline in the heating element is noteworthy. These materials, often present in high-end consumer models, emit far infrared rays for a gentler, more uniform heat and additional negative ions. Here, Valera seems to bet on the power and quality of the airflow (Smart Airflow) and on a dedicated ion generator to achieve a smooth and shiny result, rather than on a specific internal coating. The cold Touch Me nozzle, on the other hand, is a practical asset for protecting the user and allowing precise work without burns.

Adaptability to Different Hair Types

A hair dryer's effectiveness is also judged by its ability to adapt to different hair natures.

Fine and Fragile Hair: The combination of 3 temperature levels and 2 airflow speeds is crucial. Testers emphasize that the possibility of using medium or low heat with a powerful but controlled airflow is ideal for styling without aggressing delicate hair. The ionic system helps fight frizz.
Thick, Curly, and Coily Hair: This is where the 2400W power and optimized airflow show their full interest. To remove a large amount of moisture without requiring extreme heat that would damage the fiber, a high airflow rate is essential. The hair dryer seems perfectly adapted for effective pre-drying. The included diffuser allows for respecting the structure of curls by diffusing the air, which is fundamental for curly and coily hair wishing to maintain their natural volume and definition. The cold air setting is indispensable for setting curls at the end of styling.

Ease of Daily Use

This is a point where the Valera Swiss Silent Jet 8700 excels according to feedback.

Weight and Ergonomics: At 580 grams, it is among the lightweight professional hair dryers. Its elongated shape and ergonomic handle offer several possible grips (on the handle or on the body), which hairdressers appreciate for varied techniques. For domestic use, this translates into undeniable comfort and reduced arm fatigue, even on long and thick hair.
The Rotocord, a Practical Revolution: The patented Rotocord system on the cable is unanimously praised. It prevents the cable from tangling during use, eliminating a common source of frustration and offering complete freedom of movement.
Practicality of Settings: The 6 temperature/speed combinations and the "cold air" button within finger reach allow for quick and intuitive adjustments during styling.

What Users and Testers Say

By cross-referencing customer reviews and expert analyses, a consensus emerges on several points.

Recurrent praise unsurprisingly focuses on its low sound level. Users describe it as "much quieter than my old model," "pleasant for the ears," an asset particularly appreciated early in the morning or late at night. The drying power is also very frequently cited: "dries very quickly," "effective even on my thick hair." The ease of use is highly praised, with positive mentions about the lightweight feel, maneuverability, and the rotating cable that "changes everything." Finally, the quality of finish and professional design inspire confidence.

Points of caution or criticism are less numerous but exist. As mentioned, a few users temper the "silent" argument, noting that it remains a blowing appliance, simply less noisy. A minority expresses disappointment with the perceived value for money, believing that the performance, while good, does not sufficiently distinguish itself from less expensive appliances in their view. It is important to note that reviews mentioning recurring technical problems (breakage, overheating) are extremely rare, suggesting good overall reliability.

Conclusion

The Valera Swiss Silent Jet 8700 Professional Hair Dryer is not a revolutionary hair dryer in its raw components, but in the intelligent way it assembles them for the end user. Its master asset, relative silence, is not a gimmick: it is a real factor of daily and professional comfort. More than a simple noise reduction, it is the symbol of a thoughtful design that places user experience at the center.

From the perspective of hair health, its effectiveness relies on fast drying that limits heat exposure, coupled with effective ionization to reduce dehydration and frizz. It adapts remarkably well to a wide range of hair types thanks to its precise settings: fine and color-treated hair can use gentle heat without losing airflow performance, while thick, curly, or coily hair will benefit from its power for efficient drying, assisted by a suitable diffuser.

Its ergonomics – lightness, multiple grip options, Rotocord cable, cold nozzle – make it a pleasant and frustration-free tool to use regularly. If its initial investment may be perceived as high, it is justified by its professional construction, advertised durability, and the overall comfort it provides. For those seeking a powerful, versatile, hair-respecting, and above all more discreet hair dryer, the Valera Swiss Silent Jet 8700 establishes a solid and coherent reference. It is a work tool that fades into the background to make way entirely for the result: dry, healthy, and shiny hair, without the usual racket.
