1
Intelligent Heat Control
2
Dyson Supersonic Nural: Equipped with ToF sensor (distance measurement). Automatically lowers temperature when dryer is brought closer, raises when moved away. 'Scalp protection mode' that always keeps scalp temperature at 55°C is excellent.
3
Panasonic Nanocare EH-NA0J: High penetration Nanoe & Mineral. Realizes contradiction that moisture content increases even though drying hair. Finger combing clearly changes.
4
Scalp Care: Scalp is connected to skin of face. If scalp dries and ages, face also sags. Choosing dryer is anti-aging itself.
5
Speed: Wind speed is justice. Longer it is wet, more bacteria breed. Dyson's digital motor V9 blows away moisture with wind pressure overwhelming others.

Introduction: Scalp as CPU Cooler

For engineers, brain (CPU) is tool of trade. Are you roasting scalp (heat sink) covering that CPU with hot air close to 100°C every day?

Excessive heat dries scalp, worsens blood circulation, and increases risk of thinning hair in future. Stop thinking of drying hair as “Moisture evaporation work”. It should be “Maintenance of scalp environment”.

1. The Sensor Grid: Dyson Supersonic Nural

Dyson is thought to be aerodynamics company, but actually it is sensor company. New Nural constantly measures distance to head with invisible light.

ASIN: B0D4TH6D4T

Not hot even if brought close. Automatically adjusts to 55°C (optimal temperature for scalp). Also has idling stop function, wind stops automatically when placed on floor. Once used to this, ordinary dryer feels primitive.

Scalp Protect Mode

Color of LED light changes depending on temperature (Yellow -> Orange -> Red). Since temperature you are drying at now is visualized, you unconsciously look for “position not too hot”.

2. The Moisturizer: Panasonic Nanocare

Monument of beauty appliances boasting of Japan, Nanocare. Core is “High Penetration Nanoe”. Condenses moisture in air into fine particle ions and sends them into hair.

ASIN: B0B72HZHLG

Air volume unimaginable from miniaturized body. 'Moist feeling' after drying is more than Dyson. If using skin mode, can moisturize by hitting ions on face after bath.

3. Comparison: Wind Pressure or Moisture

項目	Dyson Nural	Nanocare NA0J
Approach	Blow water with wind pressure	Care with wind temp & ion
Sensor	ToF Distance Sensor (Advanced)	Ambient Temp Sensor (Standard)
Finish	Smooth (Glossy)	Moist (Moist)
Weight	About 720g (Good Balance)	About 550g (Light)

4. The Finish: Importance of Cold Air

Do not finish by drying with warm air. Be sure to finish with “Cold Air (Cold Shot)” at end. To close opened cuticles, give gloss, and fix set.

Both Dyson and Panasonic are equipped with hot/cold rhythm mode (automatically outputs alternately). Just using this drastically reduces bed hair next morning.

Conclusion: Resistance to Aging

Gloss and volume of hair are symbols of youth. It is nonsense to use cheap dryer for hair while using expensive lotion for skin.

10 minutes every day, 60 hours a year. Whether to make that time “Accumulation of damage” or “Accumulation of care”. You will check answer in front of mirror 5 years later.
