Rated 5 out of 5 by from Smooth as glass hair. I had no idea this was supposed to be used on DRY hair, lol. I apply to the lower half of my hair (ears down) on towel dried hair, then blow dry. The results are instant. I started using this 5 months ago and my stylist has commented on hair thicker and smoother my hair texture is; I have NO split ends. Used as part of the Kerastase system, it's an amazing product.

Rated 5 out of 5 by from Fabulous product I have been using fiber architect for 3 months and I would not be without it. My fine wavy , unruly hair lays down and behaves itself. I have never used a hair product better than this . It is simply wonderful. Wash , towel dry and then blow dry and your done..stellar hair emerges...

Rated 5 out of 5 by from Split ends gone Finally a product that works on split ends. I use a little on my ends and haven't cut my hair in 6 months to let it grow out and you can't even see any split ends.

Rated 5 out of 5 by from A MIRACLE! I was skeptical about using this for the first time on a VERY humid day, but I figured it would be a good test. I spend at least 5 hours outside in hot and humid weather where my hair would usually frizz and wave out of control in 10 minutes. I literally had NO FRIZZ! I couldn't believe it. The rest of the day and into the night, I kept feeling my hair and wondering where has this product been my whole life? I DID have to flat iron my hair after putting in the product. I tried a blow dryer and my hair was still frizzing a bit. 16 hours later and my hair is still shiny and smooth with NO FRIZZ. I'm hooked!

Rated 5 out of 5 by from Instant results I was about to go in and chop off the bottom two inches of my hair as they were pretty fried from being bleached and I have fine hair that tangles easily. After the first application of this serum my ends were instantly smoothed. The second time I applied it to damp hair, just one pump, and after it dried my hair looked like I left the salon it was so soft and shiny. This stuff works miracles. The smell is a little strong when you put it in dry hair but it is worth it. My hair already feels so much stronger and I've been shedding a lot less (I also use the shampoo and conditioner).

Rated 1 out of 5 by from Pump doesn't work properly I could only get one side of the pump to work and apparently one side doesn't do the trick because I notice no difference. Very frustrating wasting product only trying to get a product out of a container. I'm not into returning product so guess eating this mistake. Hopefully others will have better luck.
