Secret: KINUJO’s Silk Plate® Technology
Since its founding in 2012, KINUJO has continuously refined its proprietary silk plate technology. By reducing surface friction, it provides a smooth, stress-free experience. It gently aligns the cuticle, promoting soft, shiny hair and unlocking your hair’s full potential.
Delivers Perfect Styling Without Damage
KINUJO prevents steam explosion — a common issue in hair irons — by maintaining moisture during styling. This ensures your hair stays healthy and hydrated while achieving your desired look.
Perfect for Damaged Hair
Most hair irons cause steam explosion, where hair moisture rapidly evaporates, leading to damage. KINUJO’s silk plate technology prevents steam explosion even at 200°C, preserving hair moisture and protecting fragile strands.

I’ve used several hair irons before, but this one feels different. My hair stays soft and shiny after styling. No more steam explosion or frizz. Great for daily use, especially in the morning when I’m short on time.
Anthony Mitchell –
The 38mm size works well for my medium-length hair. I can get smooth curls without damaging the ends. It’s a bit slower than some other irons, but the results are worth it for the less damage.

I have dry, damaged hair and was worried about further damage. This iron has been a game-changer. My hair feels healthier and more manageable after every use. The silk plate really makes a difference.
Brandon Brown –
It heats up quickly and the curling results are consistent. I don’t have to worry about steam explosion anymore. The only downside is it doesn’t do straightening, but I don’t need that function.

After using it for a week, my hair looks more defined and has a natural shine. I didn’t notice any dryness or breakage. It’s definitely better than my previous iron, and I’m happy with the price and performance.
