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.

    Been Great

    I’ve been using the product for about 30 days now. My scalp feels a lot better. I’m still waiting to see the full results of additional hair growth but I know it will take time.

    Effective!!

    After a month of use , the excessive hair fall reduced to 90%. I waited a while before sharing to make sure the improvement is real. Now I can attest it is.

    Lovely serum, worth the buy!

    I’ve just started using this serum so it’s a tad bit too early to speak on the results it yields BUT I will say that I love how it actually absorbs into your scalp verse other serums that seem to sit on the scalp and leave your hair feeling oily. I have a good amount of fine hair that is easily weighed down so the fact that I can apply daily without having to worry about that is a huge plus! I bought this with the hopes of thickening the amount of hair on the sides / top of my head since the bulk of my hair is in the back and reduce hair fall out in the shower or when I brush. I will continue to use and update as / when I see results.
