did nothing for me.

luckily i bought this at cosmoprof for $60 instead of $120 or this would be even more upsetting. i realize it says 3 months but given that it also said 100% of people noticed less fallout after a month i really did my due diligence before buying a second bottle, i took pictures of everything. and by week 4 my fallout had actually increased a bit. really disappointed as i finally thought this would be the answer to my prayers.

I hate how well this is working for me!

I did NOT want to like this. I wanted to try it, hate it and feel smug about not spending the money again. As usual, I guess, K18 delivered. I should say I didn't get this for hair growth per se - but to support my hair growth efforts while using minoxidil. And the minoxidil, after 3 months, was starting to work. Except that all the little baby hairs coming in came in white! They barely showed up except as a halo of wispy white around hair line. I debated just giving up because I don't want to color my hair. Then K18 came out with FutureIQ which was supposed to help with gray hair. I got the discount for subscribe and save (which I had planned to cancel) so I could just give it a try. After 3 weeks the hairs that are coming in now are coming in brown! Not only is the new hair showing up actually visible, but my hair overall is so much softer and shinier. I haven't done anything else new, so I don't have anything else I could attribute it to. Now, I just have to figure out how to keep affording this because I am not giving it up.

Obsessed with this product!!

This product was just what I needed! I noticed the slower progression of my gray hair, and in most of my hair, no grays!! I also noticed less shedding. I have been on a GLP-1; I was shedding a lot. After using this product, it has stopped! This has been life-changing!

Love the feel!

The longevity serum is the best serum I’ve tried in terms of results and feel! My favorite thing about this is that it delivered new growth, less shedding AND my hair/ scalp never felt greasy. I have fine hair and that was very important to me in a hair or scalp serum. The only thing I didn’t notice was whether or not it prevented more gray hairs from forming. Honestly though, that is the least of my concerns with my hair so it was not a dealbreaker for me. I was very lucky to be part of a testing group through Gloss Angeles and did receive this product for free to test. However this is my completely honest review.”

Saving grace

I’ve struggled with constant shedding and thinning for quite some time now due to some medications that I’ve been taking for 2 years now and since I started using this I have noticed that it has improved dramatically

As someone who has been using it, IT WORKS.

Have been using this for about 2.5 months and have noticed the biggest difference in my hair. Not only have I noticed, but all of my peers have as well. I keep getting comments like, “Your hair looks so much thicker!”. When I shower, I notice way less shedding while detangling & my hair just feels over all more healthy. My roots sit higher off of my head & my temples are looking very full. Love that there is no fragrance, no essential oils, and no alcohol in this formulation. Noticed better scalp health immediately after incorporating. My roots are less oily & my dryness is balanced. Significantly less shedding from there. Cannot speak upon the grays as I do not have any. I also find it odd that people are leaving negative reviews without having tried the product. Let alone having tried it for the 4 weeks it takes for the product to begin to take effect.

A Must-Have for Hair Quality and Quantity

Normally I would say that the sticker price is way too high for this, but to be honest, the product actually works, and with results like these, I don't mind paying the price! The hair regrowth is visible, and there is definitely less shedding. I, without hesitation, recommend it.

Less hair shedding

I’ve been using the serum for roughly 3 months consistently and I’m really pleased with my results. I’ve suffered for a while with hair shedding and I have noticed that about a few weeks into using the serum I’ve lost less hair. I’ve also noticed new hair growth around my scalp. The serum has a cooling sensation when you put it on but I really like that feeling. There was no residue left behind, it did not leave my scalp oily either which is great. The applicator is designed really well too. I used it every night as part of my routine. I’ll be getting one for my mom since she suffers with hair loss and grays too. Thank you to Gloss Angeles Confidential for gifting this product in exchange for my honest feedback.

Helps with shedding and density

I used K-18’s Future IQ Hair Longevity Serum nightly for three months. Pros: It absorbed cleanly every time, with zero residue and no impact on styling. My scalp tends to run dry, but I had no irritation or extra oiliness, and it felt comfortable from day one. I didn’t see much change in gray coverage, but I noticed less significantly less shedding after about one month and a bit more hair density over time. Con: The daily habit was the harder part for me, planning around a nightly scalp step took some effort. If this same benefit came in a daily oral supplement I could swallow, I’d probably lean toward that instead, mostly down to my own routine rather than anything about the product. I trust K-18s science backed approach and received this serum through a partnership with the podcast Gloss Angeles. I’d recommend it if you don’t mind a nightly ritual and want support for shedding and density, just know daily consistency is key.
