Reviews Summary
Customers say this hair serum noticeably reduces shedding and promotes fuller, thicker-looking hair. Many reviewers mention new growth around the hairline and improved scalp health within weeks of consistent use. The lightweight, non-greasy formula absorbs quickly and fits easily into nightly routines. Common feedback includes softer, shinier hair and reduced flaking. Some users report less frequent graying, though results vary. A few note the high price point as a consideration, and consistency with daily application is emphasized as key to seeing benefits.

    Really nice product

    It leaves my hair feeling better and the dry patches on my scalp are healed in 2 uses. I’ve only used it for a few days but impressed so far!

    Too soon to tell

    I haven’t noticed any lessening of greys yet, it’s only been a week but it doesn’t leave my hair greasy and absorbs easily so fingers crossed it works because it is nice to use.

    Just got but hopeful

    I’ve only been using this for a week but it’s easy to use. Doesn’t make my hair greasy, I’m so hopeful that this is actually gonna help with gray, but I don’t believe it to be honest but I’ll try anything if it will help with that. If my hair will come in thicker and with less grey I’ll be a lifetime user. I’m using it in conjunction w a diff product that is only applied to the length of my hair so fingers crossed. Love all the other k18 products in my rotation
