What the gurus are saying

This serum's standout trait is how lightweight it sits on the scalp without leaving hair looking greasy or textured the next day, even with nightly use. The amaranthus cactus seed extract helps thicken individual hair fibers for fuller-looking density, and dermatologists note the serum also contains peptides, polysaccharides, vitamins and amino acids alongside an anti-gray complex with antioxidants. Apply two to three drops directly to the scalp at night and massage in; the serum vanishes into the hair without disrupting your style come morning.

    "I love this serum because your hair does not look greasy the next day. You can use it every night and your hair does not look like it has product in it. [...] It just kind of vanishes and does a beautiful job while supposedly helping minimize the appearance of gray hair. [...] It definitely does help with the density, I think in combination with everything else that I've been doing."

    "They also have an anti-gray complex in it that supposedly has antioxidants in it that help reduce the look of gray hairs. I use it every night and it does not mess up my hairstyle the next day and that's what I think is most fascinating about this serum whereas other products that I've used mess up my hair and I have to wash it the next day."

    "I was extremely skeptical of this serum when I first bought it because I was like is this going to be another issue where when you apply it to your hair your hair looks messed up, but I am shocked that when I use it at night my hair does not look worse in the morning so I'm continuing to use it. It's supposed to help with minimizing the appearance of gray hair of which I have a lot, but I'm covering up with this at the moment. It is also supposed to help with hair density."
