The brand developed Complexe Énergisant in 1984 to fight factors responsible for hair thinning. At the time, many products on the market that promised to strengthen hair and stimulate growth contained alcohol. Jean-Marie Greyl remained loyal to his values and chose to draw on the power of plants instead of potentially irritating compounds. His resulting energizing scalp treatment contains a dynamic blend of natural extracts selected for their invigorating effects on the scalp.

    I hesitated to purchase this product but I am so very happy that I finally received it. My 65 year old thinning blonde hair was just not looking as healthy and pretty as in the past but now after using this product for 3 months it has turned it around. My hair is shinier, thicker and much easier to manage. If you are on the fence with buying this product, wait no longer. You will marvel at how it literally transforms your hair. I can’t ever envision my hair routine without it.

    My scalp and hair love this product! My hair was thinning on top due to stress, genetics, and coloring. Using these treatments has allowed me to feel more confident and my hair to be the best it can be. Thanks Leonor Greyl 🙏🏻😊

    Must have . If you are losing your hair or if they are thining, get them. Or just for preventing. Whenever I see my hair getting bad, I use them. Especially if you die your hair blond.

    This product is just AMAZING!!!!
    I have tried many other treatments including pills for the hair loss and nothing has worked until I found this Leonor Greyl product. I only regret not having found it before. I have spent a lot of money on treatments that have not worked for me. I am SO HAPPY with these capsules, I only hope that Leonor Greyl never stops making them! My hair looks so healthy!!! Incredibly in just 4 months of using them I started to see the results, now at month 7 it is amazing how new hair was born and I do not have those clear shadows anymore.
    I am amazed with this product and I don’t want to stop using it.
    Note: I have been using them half of a vial every two days for 7 months now that way I can save a little bit of money too.

    This product really works! After my hair was ruined by a perm I searched and purchased so many expensive products to treat and prevent my hair from falling off and restore it from the chemicals..All waste of time and money and sadly my hair continued to fall off . It is expensive but after looked at my shelf I realized that I actually saving money because after only two months treatments I do not see any hair falling off after I shower and very little when I comb , amazing ! I finally found the perfect product that works and my hair looks so much healthier ! I already received my second box it last me approx three months ad I use it twice a week , very pleased with the results.

    I loved this product since it did work in helping your thinning hair. But you should know nothing happens over a night. I kept using this product for over a year, and the thinning area above my head did got a lot denser and healthier. Just a few problems though:
    1) the product smell exactly the same as the Tonique Vivifiant, and the ingredients seem to be exactly the same too. I tend to use both products together but no information explained how exactly these two products should be used. Are they only different on ingredient concentration?
    2) I’m always very confused about those little glass capsules. It is not that easy to apply on the product. It is not easy to crack open and once it chopped of a piece of skin on my finger when I was trying to open a capsule. And neither it is easy to carry when traveling. Is there a way to solve that? Is it possible to simply mix it with the Tonique Vivifiant so that you get higher concentration while everything can be easier?

    Complexe Energisant totally transformed my hair! As a Cosmetics Buyer I have the opportunity to try numerous hair products. Leonor Greyl’s Complexe Energisant leave-in hair loss treatment was the first product that TRULY made a difference in the thickness of my hair and it never looked and felt so healthy! My hairdresser could not believe the difference! It is truly an amazing product and every person that has a problem with thinning hair MUST use this and they will become converted to the expertise of Leonor Greyl!!!

    I’ve always had thin hair and it’s become noticeably thinner as I’ve gotten older. A friend of mine recommended this leave-in hair loss treatment and I’ve been using it for about 6 weeks now, with good results. I haven’t noticed much in the overall length but I definitely see new hair growth at the scalp (which is where I need it!) I’d say about 3/4 inch. I’ll give it another couple of weeks and see where that gets me. Very pleased!

  9. Jennie Walsh

    I used this leave-in hair loss treatment about a year ago with great results then I stopped because it was summertime and my hair seems to grow pretty fast, plus this stuff is expensive! But I’ll definitely use it again because it worked so well. I found it easy to apply and then I just styled with my hairdryer as usual.

  10. Susan Johnson

    This leave-in hair loss treatment rocks! I only use it about once or twice a week to make it last longer, but my hair feels thicker and stronger. I don’t have as much hair left on my brush and a couple of friends have even commented on how my hair looks ‘different.’
