Super good product! I've used it for about half a year and have noticed that my hair has grown much better than before. I've long had the problem that my underhair grows but my transition hair just breaks off, which makes it look thin and damaged, but since I started using this, I've noticed that it has caught up and that the hair looks thicker and healthier.
However, it is incredibly important to continue using it consistently, once a day on the scalp either morning or evening on dry or towel-dried hair, and since these are quite expensive, it quickly becomes costly, so you have to consider if it's worth it because you will need to keep using it if you want to maintain the results.
