    The Leonor Greyl serum energisant- energizing hair serum has worked wonders for my thinning and shedding hair. After hormonal hair loss most hair serums did not work for me until I tried this exact one. It has rosemary, natural botanicals and green tea which are powerpacked and natural ingredients to deal with hair loss so I really appreciate that. After some days of usage I feel like I notice a difference in the hair fall, density and overall strength of my existing hair strands.

    I’ve been using the Serum Énergisant by Leonor Greyl for about a week now, and I am thoroughly impressed. The serum is lightweight and non-greasy, making it easy to apply and quick to absorb into my scalp. Even after just a week, I’ve noticed a significant improvement in the strength and thickness of my hair. My scalp feels healthier and less irritated, and the vitality of my hair has visibly improved. The natural botanicals give it a pleasant, soothing scent, which makes the application process enjoyable. This product has quickly become a staple in my hair care routine, and I highly recommend it to anyone dealing with thinning hair or looking to boost their hair’s overall health. I cannot wait to continue using this to help my hair to become full and thick again!
