How To Get Fuller Hair With L'Oréal Professionnel’s Serie Expert Pro Longer Line

I’ve had one mane goal in mind since the beginning of summer: to grow my hair longer, stronger, and lush-looking (without sacrificing my precious length). My brunette hair has always been on the thicker side, but over the years, my ends have become noticeably thinner than the rest of my hair. I’ve been searching high and low for products that can help plump up my ends and avoid snipping them off at the salon.

That’s why, when I received L'Oréal Professionnel’s Serie Expert Pro Longer line (as a complimentary gift from the brand), I couldn’t wait to put it to the test. These products claim to penetrate the cortex of each hair strand and create a fuller, thicker-looking appearance. Read on to discover more about the length-strengthening line and my results after four weeks of incorporating them into my hair care routine.

What Is L'Oréal Professionnel Serie Expert Pro Longer?

L'Oréal Professionnel Serie Expert Pro Longer line is a must-have for anyone looking to strengthen and lengthen their strands. These products are formulated with amino acids, which help bring strength and density to the hair fiber and fill in damaged, split ends—so you can go a bit longer between trims. While nothing else quite cuts it (see what I did there) when it comes to repairing damaged ends, these are products that can help manage your mane until you’re ready to head back to the salon.

While the claims almost sounded too good to be true, I couldn’t wait to try the products out for myself. I noticed results after just one week of use. By week four, not only did my long mane feel denser to the touch, but my ends looked noticeably fuller (and my blowout looked thick and voluminous).

If you’re wondering how to use the L'Oréal Professionnel Serie Expert Pro Longer range, let me break down everything you need to know. I kicked off my length-strengthening routine by using Serie Expert Pro Longer Shampoo and Conditioner in the shower. Post-rinse, I applied the heat-protecting Serie Expert Pro Longer Leave-In Cream throughout my damp hair.

Now, here comes the fun part. I swapped out my weekly hair mask for the Serie Expert Pro Longer Ends Filler Concentrate. This product essentially acts as a filler treatment for thinned ends. I split my hair into four sections, applied the product directly to my ends, and combed through the hair to ensure an even application. Pro tip: Twist the ends of your hair after to help infuse the product into your hair. I let the product sit in my hair before thoroughly rinsing and blow drying.
