I'm using the third bottle, and I highly recommend it. I've pretty much tried everything on my hair, and this is definitely worth getting.
On the initial month of use, I thought the serum helped with decreased hair shedding. Over time, however, the hair shedding returned...
For breakage, I highly recommend the Kerastase Extentioniste Scalp Serum in the blue bottle. I have used it and got really great results.
As soon as I stopped using the product my hair loss stopped. After it made me lose half of my hair.
