Features and benefits

Why I love MIJIA High Speed Water Ion Hair Dryer H701

• High-Speed Drying with a Powerful Motor: The MIJIA H701 is equipped with an impressive 110,000 RPM high-speed motor, inspired by airplane engine principles, which generates a robust airflow of 65 meters per second. This exceptional power allows for incredibly fast drying times, significantly reducing the time spent on hair care. Users can expect short hair to dry in approximately 1 minute, shoulder-length hair in 3 minutes, and long hair in just 5 minutes, providing an efficient and comfortable experience without prolonged waiting.
• Advanced Hair Hydration with Nanoscale Water Ions: This hair dryer incorporates a breakthrough Double-Needle Water Ion Patent Technology that condenses air moisture into high-moisture nanoscale water ions. These ions are delivered directly to the hair through an independent cold air channel, ensuring deep nourishment and preventing loss due to high temperatures. Compared to regular negative ions, these nanoscale water ions have a higher moisture content, evenly enveloping hair strands, helping to close cuticles, and providing a spa-like experience with deep hydration and moisturizing benefits.
• Enhanced Hair Health with 200 Million Negative Ions: Beyond hydration, the H701 releases 200 million negative ions. These ions effectively neutralize static electricity, which is a common cause of frizz and roughness. By reducing static, the hair dryer helps to smooth the hair cuticle, resulting in a sleeker, softer, and more manageable finish. This dual-effect hair care, combining water ions and negative ions, leads to visible improvements in hair moisture (+50.40%), shine (+27.60%), smoothness (+36.30%), and elasticity (+42.00%).
• Intelligent and Consistent Temperature Control: To prevent heat damage and ensure gentle hair care, the MIJIA H701 features NTC intelligent temperature control with 100 temperature detections per second. This precise system maintains a constant temperature of 57°C, which is optimal for drying without over-exposing hair to excessive heat. This intelligent control, combined with gentle airflow, minimizes damage, making it suitable for all hair types and promoting healthier hair over time.
• Versatile Drying Modes and Quiet Operation: With 13 distinct drying modes, offering various combinations of wind speed and temperature settings (including 4 temperature settings and 3 speeds), the H701 provides unparalleled customization for diverse hair types and styling preferences. This versatility ensures a comfortable hair drying experience year-round. Furthermore, the device integrates multiple noise reduction technologies, with each fan blade finely tuned and airflow optimized to ensure a gentle and quiet operation, enhancing the overall user experience by minimizing disruptive noise.

Pros and Cons

Strengths & Weaknesses:

What I Like
— Extremely fast drying capabilities due to the 110,000 RPM motor and 65 m/s powerful wind speed.
— Advanced hair care benefits from 200 million negative ions and high-moisture nanoscale water ions, visibly improving hair health.
— Precise and consistent 57°C temperature control, with 100 detections per second, prevents heat damage.
— Highly customizable with 13 drying modes, including 4 temperature settings and 3 speeds, catering to various hair types.
— Operates quietly thanks to multiple noise reduction technologies, ensuring a pleasant user experience.
— Lightweight design at just 390g, reducing arm fatigue during use.

— The device comes with a CN plug standard, necessitating an adapter for use in other countries, which some users found to be of low quality.
— Some users reported a lack of English instructions, potentially hindering initial setup and understanding of features.
— There is a risk of receiving an incorrect color (e.g., grey instead of purple), leading to customer dissatisfaction.
— One user experienced hair becoming very dry despite the advertised ion technology, suggesting potential variability in results.
— A few reports of units being non-functional upon arrival, requiring returns.
— One user noted a scratched button upon receipt, indicating potential quality control issues.

⭐ 5.0/5 | AliExpress Shopper: The hair dryer is good and works well so far. However, regarding the store, I have mixed feelings. They seemed to fulfill my request for a shipping note, but I ordered purple and received grey, even though purple was specifically desired. I’ve attached a screenshot of the order. The most disappointing part is that the grey version could have been purchased for €8 less. It is what it is. The child for whom this hair dryer was bought was very upset, as she really wanted purple. The gift was a failure. It’s a shame. The store gets a failing grade. Fail.

⭐ 1.0/5 | AliExpress Shopper: I tested it 8 times before leaving this review, and this dryer is not good. It dries fast, but the hair becomes very dry; it seems to remove all the natural moisture from the strands. Delivery was quick, though.
⭐ 5.0/5 | p***p: Very good.
⭐ 5.0/5 | P***o: Excellent product.
⭐ 5.0/5 | M***i: Fantastic.
⭐ 1.0/5 | AliExpress Shopper: I just received the Xiaomi Mijia High Speed Water Ion Hair Dryer H701.4 with high expectations, as a friend recommended it. After plugging in the device, the lights illuminate, but the hair dryer remains silent and does not function. I attempted multiple times, ensuring the plug was properly inserted, but there was no change; the dryer is completely inoperative. The plug is a US version, which is correct for Canadian users. I have no option but to return it.

⭐ 5.0/5 | A***u: Good quality.

⭐ 5.0/5 | AliExpress Shopper: Very happy with it.
⭐ 2.0/5 | B***o: I ordered the European version, and instead of coming with a European cable, it arrived with a shoddy adapter. Had I known, I would have ordered it from another store that would send what I actually purchased.
⭐ 5.0/5 | AliExpress Shopper: Fast delivery.
⭐ 4.0/5 | a***o: Good, but not perfect.
⭐ 3.0/5 | AliExpress Shopper: Decent.
