Reviews Summary
Customers say this scalp treatment feels refreshing and lightweight on application. Many reviews mention reduced hair shedding within the first few weeks of use. The gel-like texture absorbs well, though some note it leaves residue that requires morning washing. Reviews indicate visible results typically appear after 2-3 months of consistent use, with users reporting new growth particularly along the hairline. While most appreciate the easy-to-use applicator, some find daily washing requirements challenging for their hair care routine. The treatment works best with regular nightly application, though experiences vary with different hair types and washing schedules.

    Causes insane hair fall

    Can't say I saw any growth whatsoever over the course of using this as intended AND I saw my hairfall get a LOT worse, like clumps during my time using this. I can't confidently attribute that this product is what caused my hairfall to get as bad as it did, but I will say that almost as soon as I'm done massaging it in, hair just seems to slide out into my hands. Also, it feels so gross: It leaves a residue that looks simultaneously greasy and like big flakes of dandruff. Here's a photo of the hair I lost after a single use. I was already dealing with thinning hair/hair loss but this just seemed to make things so so much worse.

    Thank you so much for taking the time to share your feedback, Rusty.

    We're truly sorry to hear about your experience with our Caffeine Stimulating Scalp Treatment. It's particularly troubling to hear that you didn't see any improvement in hair growth - this is absolutely not the experience we want any of our customers to have. While many customers find our scalp treatment helps support their hair care routine, we understand that everyone's scalp and hair can react differently to treatments, especially when dealing with existing hair thinning concerns. We also understand how concerning it must be to notice the texture and residue issues you've described. We take your feedback very seriously, and we'd love for you to reach out to our askINKEY Team, as we would greatly appreciate the opportunity to understand your experience further and explore how we can make this right for you 🖤

    It's pretty good I've been using it for two months now

    It doesn't leave the hair that oily if you decide to not wash it off the next morning but it will probably have to be a slick back day
