L’Oreal Hair Expertise Fibralogy Review


When I find a product that promises to give me thicker hair, I definitely pay attention. And when that product is less than $5, I put it in my basket. In May, I picked up the new L’Oreal Hair Expertise Fibralogy Shampoo, Conditioner and Thickening Booster. I was intrigued by the promise to make your hair thicker “wash after wash” as it focuses on expanding the hair fibres. Of course I was slightly skeptical, but more than willing to try it out.

lorealfibralogy2The shampoo works like any other (wet hair, lather, rinse out), but the Thickening Booster is an interesting step. Rather than being a treatment you apply after you’ve shampooed and conditioned, this serum like treatment goes in as an addition to your conditioner. After shampooing, you add a small amount to your strands, then put the conditioner on over top. The added step of the thickening serum, which is said to have the highest concentration of Filloxane (the miracle ingredient) to add instance fullness and thickens your hair the more you use it. You can either apply it just once a week, or twice for more intense results. The conditioner is much like any other good conditioner. It’s thick, makes my hair feel soft, but doesn’t weigh it down.


After my first use, I did notice a small difference in the thickness of my hair. It felt thicker when I pulled it up into a bun, and it continued to feel thicker the more I used it. I haven’t used it this system each time I wash my hair (because I like to switch it up occasionally and still use a clarifying shampoo once a week), but I do use it at least once a week. Now that I’ve been using it for over a month, I am starting to see the results are still there, and that my hair really does feel thicker. I’m not sure that it looks thicker though.

lorealfibralogy4As far as the general condition of my hair, it hasn’t changed drastically since using these products. My hair is still dry (because of my love for heat styling and needing a trim), but it hasn’t worsened. I have heard of other people experiencing dryness after continued use though, so perhaps it depends on your hair type, or how often you use it. Overall I’m quite happy with these and would definitely repurchase them. I like that my hair isn’t feeling so thin lately, and that I didn’t have to spend $30 for one serum for it to feel that way.

    I might suggest this to my sister! She has the thinnest hair ever and it just takes forever to grow because it breaks off.

    Also: I’ve only just started getting into the beauty blogger world and looking at things. I’m a 25 year old woman who is just starting because of massive insecurities and depression. I have to say that your blog is so uplifting and I’ve looked at it for a week now, going back through every post. It makes me smile to see a great beauty blogger from Canada, and one who seems so sweet! (I also suffer from nice girl syndrome) I so look forward to all your posts and thanks for giving confidence, although probably unintentionally, to those who have a hard time trying to figure things like this out.

    (I’d love to see wedding photos ((or pre-temple wedding photos, as I assume you did that from your posts)) and a post about that!! Wedding make up is so popular)

    • It made my day to read this comment! I’m so glad that something I said meant something to you. Thank you so much for reading and I hope that you come back!

  • I’ll trade hair with you! I need to go in and have mine professionally thinned! It gets so thick it takes forever to dry and traps oil like crazy!
    It’s not that the strands are thick, they’re actually very fine… but there’s a lot.
    What clarifying shampoo do you reccomend? I think I’d like to try one out.

    Thanks 🙂

    • Ha! I used to have hair like that, but within the last five years or so it’s thinned out a lot (not sure why).
      I use Bumble and Bumble’s Sunday Shampoo for clarifying. It’s really good, and since I use it no more than once a week, it lasts for ages.

  • I checked the ingredient list when I got a sample and decided against using it, as it contains mostly silicones and some sulfates (which I tend to avoid, as they make my hair super dry). This “Filloxane” sounds like a fancy name for a useless thing to me, but of course I might be totally wrong there, as you are seeing results. Maybe I should see if I have this sample still anywhere around?

    • I could see why it would dry your hair out. I usually don’t have too many issues with sulphates, so I don’t worry about it. I’d try it though, if you can find that sample. I’m not sure if the thickness will last forever, though I wish it would.
