Great quality but Not enough product. Super sad that it ran out after my 3rd or 4th use.
It didn’t even last me a week. I didnt over use it just a few pumps. From the three or four times that I used it seemed great and easy application but again it was out after my 3rd or 4th time using it, it was empty. I switched to lilyeve. I would’ve loved to continue using the product but because it ran out so quickly and the price for it.. I can’t. Maybe if the company reached out to rectify I would switch back. Not sure if that’s normal. Thought it would maybe last me like three weeks to a month. Super upset because I really enjoyed it at first.

Small amount but works great
Great product but the price is rough for the amount inside. I am purchasing again just wish it was cheaper or came with more.

ineffective
I loved the product but the application of the roller doesn’t work! I used it once and now it won’t dispense any serum

A family favorite, especially for fine hair
I have fine hair, and had significant thinning around my temples due to styling and genetics. I've have tried a number of different products and this works the best. In 1 month, I've grown at least 1-2 inches of baby hairs. Although some of the new hair is gray, a win's a win! I have other family members that use the same solution and have seen similar changes. I also use this with Dr. Groot's Hair Thickening Shampoo, and Miracle In-shower treatment. When I was using only the Hair Thickening Shampoo, I didn't see much of a difference. However, when I added this serum plus the Miracle In-Shower treatment I saw an improvement with hair growth. Just fyi, it may take longer than 2 weeks to see a change. I'm not sure how folks are out of solution after a few uses. I wear this solution once a day and its lasted me a month already - and I still have plenty left. Perhaps to get the most of the product, when it's not in use, make sure that the pen stands upright and that you ensure the button to pump the is turned off to avoid spilling.

Didn’t see any results.
2 stars. I gave it a try, but I’m not convinced it works. It’s supposed to use for 2 weeks to notice any results, yet my bottle was empty in 7 days, so I never got to see real results. For the price, that’s disappointing. Maybe I’ll try it again later, but I’m going back to coffee and rosemary water for now, that I know it work.
