    Working well thus far.

    I've been using this (plus the Thickening Foam) for about a month now and I did start to notice some small improvements after the first two or three weeks along the left side of my hairline, where I've previously noticed some hair loss the most. I've also found my scalp/roots are able to absorb this very well, unlike another hair lengthening serum I test a while back.

    The one downside to this is that, since using this, I've noticed I've been getting pimples around the areas of the scalp that I've been applying the most. I don't know if this the fault of the serum, the foam, both, or maybe I'm just using too much, but that's something to keep in mind.

    Soothing & Great Preparative Step for My Routine!

    Love this product! Not entirely sure how it's working on my hair since I'm taking so many steps to protect it from breakage/falling, but it certainly doesn't hurt. It's a great experience to use it, too—it feels cool as I apply it to my (dry but not otherwise irritated/red) scalp after showers (soothing & making it easy to tell where I've applied). It also feels good to have something between my scalp & the hair products I use like mousse, which has made it feel itchy in the past, after the first couple days of fresh hair. Excellent relaxing lavender/herbal scent, prolongs my hair between washes (letting this bottle last around a month or two on average!), soothes my scalp before adding in hair products—it's great

    So far so good!!

    So far feels very nice on my hair. My hair doesn’t get oily too fast and it has felt a lot softer! I haven’t noticed a change in length yet but I am just starting out with it.
