I was so excited to try out fibrology, especially bc I have quite thin hair, and this product is supposed to help thicken my hair. Firstly, the smell of the shampoo is fantastic! So sweet, which was a pleasant surprise. The conditioner doesn't have as strong a scent as the shampoo, which is slightly disappointing, but if the thickening formula works, I don't really care ! ;) my hair felt slightly thicker after a few uses, which I am very happy to report. Sometimes these "new" products aren't anything special, but I'm happy to say that I find this one lives up to what it promises!

I have used this product 4 times now. I did notice that my hair was fuller after 1 use. It seems to be thicker to. I did measure my ponytail and will wait a bit longer to measure it again to see if there is a difference. I have fine hair that is colour treated and shoulder length. I did notice that my hair feels dry when I wash it. Plus my hair has static when I brush it. I have to use the products I use in the winter to calm this down. I guess it is the drying effect the shampoo has on my hair. The scent is ok not my favorite as I like fruity scents. The smell is unisex and my husband loves it as I had him smell the bottles. I am not sure if I would buy this product for regular use. I may just to have it on hand to add body to my hair when I want to style my hair for date nights

I was skeptical of this at first but I've definitely noticed a difference. I wash my hair every other day and my hair is noticeably thicker after every wash. I have very fine hair with no volume and it definitely has more oomph. It doesn't seem to take a lot of shampoo or conditioner to really work up a lather which means it will last a lot longer. The only thing I don't like is the chemical smell to it. Would definitely recommend for someone wanting to add some extra volume and thickness to their hair. I tested the Fibrology line for free, but all opinions are my own.

I was so excited to receive my very first Vox box the other week. Beautifully packaged in it were all three of the new L'oreal Fibralogy products; shampoo, conditioner and booster. All three products have a lovely, long lasting smell. It reminds me of the way my hair smells after a visit to the salon! The shampoo offers a rich lather and does a great job of cleaning the hair. The conditioner is thick and rich and leaves my hair feeling slick after rinsing. After drying my hair, it does look fuller and has more bounce. The ends are a little dry feeling, but I may just need a trim. Overall, I like the shampoo and conditioner and would use it again.

I received these products to try for free from Influenster. I was soooo excited to try them as I have terribly thin and fine hair. I feel as though it might be thickening my hair, it seems to take longer to dry with the hair dryer (or maybe it's just me hoping). I love the smell of the products. I don't love how my hair feels after though. It seems so limp and lifeless. It's not soft at all. This is something I really need in a shampoo and conditioner combo.
As mentioned above, I received these products for free to test and this is strictly my own opinion.

Even when I have thick hair to begin with. I was wondering if this would still work with my hair without weighing it down and it was awesome! After one use my hair feels light, voluminous, thick, and soft. My hair is very annoying, its flat, thick, and oily. At the end of the day my hair didn’t have that greasy hair or started to look greasy. As a woman with thick hair, you can not imagine how hard it is to find a shampoo and conditioner that works for your hair. I was given this sample for free, but all opinions are mine. I am not paid to write this review.

First of all I love the sizes of these products! They're so large and just great! In my opinion, th thickness booster smelled the best out of all 3 products! The shampoos works well when your hair is extremely wet rather than a quick shower in and out ( depending on your hair length). I found that I was most impressed with the conditioner because my hair was exceptionally silky! I loved it! I left the conditioner and the Boost sit in my hair for a few minutes while i finished the rest of my shower. My hair smelt great, felt great and looked great.

Well L'Oreal Paris sure out do themselves this time. I am in love with this product . Testing this product for L'Oreal and Influenster has been a ball!! The System is great they smell amazing and the instructions are simple to follow!! The shampoo did not leave my hair feeling dry and brittle. Instead it was soft and easy to wash out. The condition is creamy and leaves my hair feeling silky smooth! Oh did i mention they smell AMAZING!!!!! will definitely be recommending this to everyone! I tested the Fibralogy line for free, and all opinions are my own.

I love the Fibralogy shampoo! It's one of the best drugstore shampoos I've used. It's a creamy formula, that lathers well, and leaves my scalp feeling incredibly clean. The conditioner, while similar in consistency to the shampoo, is great but could be thicker. I prefer thicker conditioner, as my hair is so damaged. But, used together, these products are very effective at making my hair look thicker. My second-day hair also looks so much better thanks to these products! Disclaimer: I was sent these products from Influenster for free to test. But all opinions are my own.

I received my sample in the mail from influenster, and oh my god. This thing really works!! I have incredibly thin hair, and the second I put the shampoo in my hair I could feel it become full. The conditioner was very light weight but made it easy to comb through as well, especially compared to a lot of thickening conditioners that don't do that. The smell was also really good! Almost a raspberry - blueberry scent. I'm going to have to ration this sample until I can buy my own because this is a must buy for those with thin hair. Thanks influenster!!

Would anyone buy the booster? I used it for the first few washes but found it didn't make a different. The conditioner added the right amount of volume. I also had an issue with it being a clear liquid... on wet hands. It makes no sense and makes it hard to see how much you have in your hand. I lost quite a bit by not realizing how thin the liquid was and that it just came out without any effort or squeezing. Oops!

I received these products in a voxbox to try for free for my honest opinion. I have tried it so for for three days. My hair was very thin and dry as I used to colour it alot. I don't no more but my hair never recovered. One day one of using these three product my hair was fluffy and full of life and even had a beautiful shine to it.on day three I could notice my hair was thicker.or as I took pictures of my hair in a ponytail from day one till today,day 5. I have posted the pics on facebook and Twitter etc for all to see. My hair today is full of life and thicker than it has been in many years!
