I think it works great. I noticed an immediate difference once I started sealing a few weeks ago. My hair just felt more moisturized as they day wore on. Also it contributed to the whole "my hair feels like seaweed" test you do when you put your leave in on. I take some KCKT and mix it with a few drops of jojoba in my palm before I apply it to my hair and I swear it disperses even better and faster. It's a nice, slippy, slick feeling. My hair feels very healthy! Grapeseed works just as well though for sealing. But I've always like jojoba for skin care so it figures my hair would like it too.
