    Hard to operate

    This bottle is very difficult and time consuming. I feel it would be easier as a spray. I also tried using it at different times. What I found is I liked to apply with my conditioner in the shower and let sit for about 5 minutes. When I applied it after the shower or to dry hair it made a weird residue on my hair and made it very difficult to brush and more breakage.- Originally posted on kerastaseusa.com

    So much love for this

    This is by far my favorite. The smell and the ease of use is amazing. I love the idea that adding it to your roots to save your hair from falling. I noticed that within a week or so I was not shedding hardly at all compared to how I was before I was using the serum. Definitely recommend the entire genesis kit!- Originally posted on kerastaseusa.com
