I've been using this set for around 3 weeks. I've noticed a little bit of growth around one of my trouble spots from using the oil regularly. My hairline does seem to be improving as well. It does make my hair a little too oily (less is more) but my scalp absorbs it very well. I've noticed improvement with my dandruff. I barely have any flakes. I also am not experiencing product buildup on my scalp. I'm really happy with this particular oil blend. The oil and the spray smell nice and pleasant as well. It's a light natural fragrance. I like to use the spray to refresh my hair and scalp.
