Pricey but worth every penny!
I have been using for about 2 months and LOVE this serum. I am struggling with a bit of hair loss with menopause. I read the reviews and ordered and am so glad I purchased and it is worth every penny! I have overall oily skin and have to wash my hair every other day, so I was worried that this might make my hair feel too greasy. I have not noticed any greasy or heavy feel with this product! After showering I apply this to my towel dried hair and it feels great after I air dry or blow dry my hair. I LOVE the scent - I read the reviews that this smells like a tic tac and this is spot on and not at all overwhelming! I have noticed a big decrease in hair loss and I use every other day and follow with a strong scalp massage after applying. I will stick with using this product and love the results!

Intoxicating Natural Fragrance
Does what itโs supposed to but the differentiator is the soothing natural clean scent. I would buy a body wash, candle literally anything in that fragrance just put it in my cart. No cap. Straight facts my dogs.

Pleasant smell, will continue buying
Only been using 3 weeks so no noticeable difference in hair growth. But compared to others I've tried, this one doesn't leave your hair greasy, easy application.

Less Hair Shedding
I started using this product due to hair shedding. The reviews were very helpful and what I discovered is scalp health is just as important as what you put in your body to promote healthy hair. Iโve been using this product for about a month and notice a big difference in shedding. My hair sheds the most when I wash it and I can see a difference in the amount of hair that comes out in this one month of using this product. Do your research, I have low porosity hair and moisturizing the scalp is very important. Pricey but recommended.

Led to a flare up of flakes - not for my sensitive scalp!
Based on the reviews and my needs for my hair, I was looking forward to this product. I have low porosity, color treated (non-bleach), waist-length, medium/coarse hair. I have strugggle on and off with flakiness and dry scalp. All summer, my hair had been doing really well and hadn't have any flare ups with flakes. I've been searching for a reliable, effective daily scalp serum that I could use to maintain scalp health. With my hair/scalp characteristics, I focus on finding water-based, light-weight products, however this does contain fragrance and other ingredients that could potentially irritate an already sensitive scalp. well within two weeks of using the product every few days (it's always perhaps worht mentioning that I wash my hair once every 4 days), I got a flare up in my flakes and they've remerged. This product is slightly thicker, and I probably wouldn't classify this as a light-weight prodcut compared to say, Kerastase's scalp serums which have less viscosity than this. I feel that in addition to perhaps not washing my hair every day, when I 'd use it it was building up on my scalp and made my flakes worse. So, it didn't work for me. And not to say it won't work for you! But it's important to know what kind of scalp/hair characteristics you have in order to find a product that will best fit your needs. If you have similar scalp/hair conditions, you may want to reconsider this. Unfortunately, that's $50 out :( but I decided to try Nรฉcessaire The Scalp Serum. 5% Capixylโข + 1% Hyaluronic Acid, which looks like, and hopefully will be, more amenable to my scalp.

Scalp serum feedback
The product is good as a volumizing agent. All the hairs are separated from each other. No-greasy formulation. Observed no other positive effect.
