"No smell, no weird texture, clearly largely water based, perfect. After years of using Minoxidil, i kept losing my hair, and had those well known bad side effects on my skin. No side effects at all with the this."

Customers say this scalp treatment shows promising results for many users. Many reviews mention seeing baby hairs and reduced shedding within a few weeks to months of consistent use. The lightweight formula absorbs quickly, though some note it can leave residue that requires morning washing.

Didn't work for me
I used two bottles of the product and didn't notice any change. It's relatively easy to use and has a pleasunt smell.

Nozzle is not practical
On the bottle, you've written different instructions on how to apply this product. Also the video shows a woman applying the product directly from the bottle from the scalp. However, the nozzle is of the "on or off" type, and in two days, already half of the bottle is gone. I probably change to another brand with a better bottle. The product itself seems okay, and it doesn't make my hair oily or weird.

Hi Katja, thank you for such useful and detailed feedback - we're glad the product itself is working well for you. That said, we're sorry the nozzle isn't the experience you want.
We also want to apologise for the confusion between the instructions on the bottle and the application video. Please do reach out to our Customer Experience Team directly (ask@theinkeylist.com) - we'd love to make this right for you and look into the dispensing issue further. 💙
