So far so good first time I've used this particular product I do like it it's just I haven't had it long enough to really judge whether it's working or not but I do like the product it does smell good and everything else they have works so I'm sure this is great as well

My gray strands were becoming far too noticeable on my very dark brown hair, and even deposit-only hair dye was causing thinning/breakage. I'm almost through one bottle & a few not-gray hair sprouts are coming up. No change to current grays as of yet but will continue to use to see further improvements, hopefully. Only side effect is slightly oiler scalp but not a major concern.

Wish I'd known about this earlier. Relief within days and no scalp dryness. Trying the other products too.
