I have thin, damaged, and bleached hair + tape extensions. I also have an oily scalp and dry lengths, not a great combo, in other words. I've been using the kit for a few weeks, and even though I haven't noticed any difference in hair loss, my scalp feels very balanced. The shampoo is definitely quite drying, but as long as you soak your hair in moisture afterward, it doesn't show. I've also solved it by using the conditioner on the "upper scalp" where I have no attachments, and then a more moisturizing conditioner on the extensions.
Both my own hair and the extensions look fantastic after these weeks, and the leave-in cream gives insane volume. So I can highly recommend it to anyone with the same hair type as me!
