Great smell, keeps hair healthy, especially when using heated tools
This product is amazing! It smells wonderful, and can be applied on wet or dry hair. In addition, it does not make your hair greasy or sticky. It also has an element in the formula to help protect from heat ie curling irons, hair dryers and flat irons. I highly recommend this product. Too, a little goes a long way!

Works great
A bit pricey, but worth the money. This product works wonders on my hair, making it soft and silky, combs right through, without pulling or snagging on split ends. Great product

Left my hair dull
Not a fan at all! It left my hair lifeless with no bounce and my curls didn’t hold. Returning too because it came without a seal as if i was given someone else’s returned bottle, but after two uses i see why it was returned it just doesn’t justify the price.

Nice fragrance, Lousy Botle
The pump on the dispenser broke off and does not work at all. I open the top and pour some in my palm, so ease of use is not great. There is some improvement, but not enough to justify future purchases. Most of the products by IGK are well worth the price, but not this one.
