  • the best
Love this scalp serum. I've been suffering from hair loss since my 30s. (I'm 60 now). I've been trying everything available in the market with little results. This is the ONLY thing that has been working for me. I've been applying in the mornings, or at night. My hair looks so good and fluffy, and i guess i have new hair growing after 2 months. Even people compliment my hair. I'm very happy. My first bottle lasts me 3 months. First bottle cost me $52, and I ordered today is $34 (?) ... show more

  • I dig it 😎
I bought this hair serum not expecting very much (I have "old-soul" hair). I'm pleasantly surprised. I've been using it for 6 months now; the smell is fresh and light ( I get compliments often on the smell), the serum is soothing on the scalp, I have baby hairs popping up (pics to chuckle at) and the rest of my hair has grown out really long. It's not instant; however, it does work. ... show more

  • AMAZING!!!
First off the smell it’s addicting I absolutely loved it, the photos are two month apart. I got to help grow my peek areas and from just two months of using it 3x a week I can definitely see a difference. It does make my hair look wet for about 10-20 minutes but then it drys and it’s very soft, doesn’t leave it looking oiling and it’s very light on the hair! ... show more

  • So far so good with thin, oil prone hair
I have very thin, fine hair and while I haven’t used it long enough to see if it really works, I’ve applied when my hair has been wet and dry and it hasn’t left my scalp or roots oily or greasy looking at all! It also does smell great. The only thing I hate about this is the awful dropper design - not enough to not recommend it but omg someone with some sense needs to redesign that part ... show more

  • Is this a dream?
I wish I took before photos of my hair before using this because no one would believe me. This stuff is amazing, super lightweight, not oily or greasy at all and the smell is really nice also. I've been using this once a day ONLY for two weeks and I can VISABLEY see the difference in my hair. It is thicker at the temples where I was thinning and I swear my hair is actually growing. LOVE it! ... show more

  • WRONG PRODUCT
I got this serum for the first time through Sephora and saw this on sale here so I bought more off Amazon! ITS DIFFERENT. The feeling of the original one is a clean tingly feeling and smells so good. This smells like someone put soap in a bottle. I WANT A REFUND

  • Worth the price
This smells amazing! It’s a Clean and crisp smell with a hint of mint but won’t leave your head smelling like anything. It has helped with my oily scalp and I hardly have any need for dry shampoo now. I use this with a scalp massager and it has given my roots extra lift that I usually lose 1-2 days after washing. I’m only on my 2nd bottle but can visibly see and feel a difference in my hair ... show more

  • I will update later if I notice changes - updated
I purchased this serum April 9th so I have only been able to use it about 2 weeks and I can’t say I’ve noticed much of a difference. My hair fall still seems a bit excessive but I know these things take time. I will say that the serum smells super good and I can apply it daily without it making my hair oily. My scalp is still dry and a little flaky even after using it though so I’m thinking of switching shampoos. I will definitely come back if I notice a difference or lack of one, but I certainly hope I see something for the price. Update: I used up the bottle a couple months ago and I wasn’t very impressed. For 52 dollars, I expected to at least see an improvement in the dryness of my scalp and overall scalp health like it says it will, but it didn’t feel like it did anything. I didn’t notice really any new growth or lessened shedding. The one thing I did like was that it was cooling on the scalp and very lightweight so it didn’t leave a heavy residue feeling like other scalp serums. But I won’t be purchasing again. ... show more
