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.

    No huge difference

    I have been using this caffeine stimulating scalp treatment over the past few months as I have thin hair. I tend to wash my hair 3 to 4 times a week so use it when I wash my hair. It cleanses but does not leave my scalp and hair feeling dry or stripped. I can't say I have noticed any huge difference in the density or volume of my hair or any extra hair growth. I have afro 4c hair. I'll continue to use for a longer period of time to see if it does make a difference.

    Hi Elaine W,

    Thank you for sharing your detailed feedback about our Caffeine Stimulating Scalp Treatment. While we're pleased to hear that the product cleanses well without leaving your scalp and hair feeling dry or stripped, we understand your disappointment in not seeing significant changes in hair density or volume yet. Hair growth cycles can vary greatly from person to person, and visible results may take longer to become noticeable. While we strive to create effective formulations that work for all hair types, we understand how disappointing it can be when you don't experience the immediate results you're hoping for. Our knowledgeable askINKEY would be delighted to discuss your experience further and explore ways to help you achieve the best possible results from your hair care routine 🖤
