Reviews Summary
Customers say this scalp treatment feels refreshing and lightweight on application. Many notice reduced hair shedding within weeks of consistent use, with several reporting new baby hairs appearing after a few months. The gel-like texture absorbs well, though some find it leaves residue that requires morning washing. While experiences with overnight use vary, frequent reviewers mention seeing best results after 2-3 months of regular application. Those with fine hair note it works best when followed by morning shampoo, while others appreciate its non-greasy formula.

    Result after a couple weeks

    This is my first review, as I am still in the middle of the treatment. But I wanted to share that after the first 3 weeks, I am already feeling baby hairs growing. Even verifying this with people who have seen my bald spot, they confirm there is something happening.

    I got the treatment from my mom, who used it after cancer treatment, and she has more hair then before. I am excited for the next phase.

    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
