Aveda

Aveda

It's a bit pricey, so it's an item I always make sure to bring back duty-free.
It's too expensive, so I use Silk Therapy one day and Aveda the next, but I can feel the difference in my hair when I use Aveda.
It isn't dry and frizzy, static electricity is gone, and it doesn't feel stiff when I comb it.
Since it protects hair even at temperatures over 450 degrees, I think it would be good for those who use hair irons a lot.
