I dont think so. I've been using it since February. Since I did a major trim in January and I've babied my ends since then, I've had only about 5 split ends since January, and it's October! It's re-friggin-diculous! My secret: I've been putting HE LTR Leave-in on my ends and then coating with castor oil. Actually, I do that to my whole head, but I concentrate on my ends. That mess has been working, suriously! I was the split ends Queen beforehand. I cannot see that any properties in chlorella, all vitamins and minerals, that cause the hair to be dry or to split. But this is JMHO.... HTH
