I have sensitive skin and was looking for something that doesn't contain plant extracts, and I found this. I use it to straighten my hair in the morning. My hair specs are: normal thickness, a fair amount of volume, and straight enough to curl. I use Jemile Fran shampoo, iau conditioner, and Gokujun emulsion as a leave-in conditioner. I have short hair, so my morning hair styling involves straightening my hair and curling just my bangs with a 120-degree curling iron. I used this to straighten my hair all day and was surprised by how my hair stayed moisturized and my flyaway hairs didn't fly away. I also feel like my hair is more moisturized. I wouldn't recommend this to people who are sensitive to scents, but I'll definitely be buying it again!
