The bottle seems to last quite a while which is nice and it’s obviously wet on your hair but doesn’t dry greasy and I do think it’s helping my hair to grow a little. I do love inkey list products anyway

There’s growth
I have alopecia areata, and have tried a lot of things throughout the years to no actual avail. Whether this was coincidence or not, after two weeks of use I started getting white regrowth. Mine works where the white grows through first and then falls out, to be replaced with coloured hair. The white that’s grown through is stronger, thicker and healthier than usual. It also smells nice.

Seems to work great
I can't say with certainty if this is directly responsible for the noticeable improvement with my hair the last few weeks (as I have applied two additional products) but I'm pretty sure it is...and therefore I quite confidently praise this product as very effective for me personally.

A solution for seasonal shedding and perimenopause thinning?
I have been using this product for a week and so far the results look promising. My particular issue is seasonal shedding, whereby I lose a lot of hair in the warmer months, particularly July and August, which then eases back in the colder months. That, combined with general perimenopause-related thinning, means I simply cannot grow my hair past shoulder-length without it looking ratty at the ends. Which is a downer because it suits me better when it's a bit longer. I have been applying the treatment every night before going to bed. It is cool to the touch, easy to apply on your finger tips and doesn't really smell of anything to me. On the first application I noticed the skin on my face felt really dry the next morning, but I figured it was because the treatment was migrating on to my face from the pillow as I slept. Putting my hair in a fine wool snood overnight after treatment seems to have solved that one. My hair is not greasy in the morning, and the treatment seems to have soaked in and disappeared, which is great as, being very fine and curly, I only wash and brush my hair every three days. Just spritz, scrunch and go. Then, when I washed my hair for the second time after starting the treatment (at the end of week 1), I discovered that only the tiniest amount actually came out in the brush (see picture, measured against a one penny piece - about the same size as a 1 cent). Admittedly this is the winter, so I would expect to be shedding much less now anyway, but still it seemed to be a particularly small amount, after three days since my last wash and brush. Could it be working already? Admittedly the real test will come when the days lengthen and the temperature rises, so this is a review 'part 1', which I will come back to when I have continued the treatment through the summer. Handily, Amazon offer this on a subscription, so I won't run out. I'll be back with an update in 8 months or so....

It’s brill and really works
This stuff is brillll. I had an issue with my hair falling out so I got this serum to try. I been using this every night before going to sleep and when I awoke it’s dried. Anyways, I did this for a week and it worked it really has. No hair loss at all even when I brush my hair first thing on getting up. I would highly recommend this serum to anyone who has this issue I had.

Works for me
This is my "go to" once a week hair treatment. Been using it for months and I mix it with other hair oils I use to give it that extra boost for my hair and I can see a great difference! Remember though, consistency is key.

Great. It works
I've been using this for a couple of months now. I use it twice a week on the days leading up to when I'm going wash my hair. Overall my hair feels thicker. I'm not sure about breakage at the min but it's definitely helping my hair and I will continue to buy

Hard to say if working as yet - only a few weeks
They say you need to use hair loss/growth products for at least 3 months to know if it is working or not so, hence 3 stars. As its only been approx 1 month its hard to say. I am seeing some small density improvements and very slow growth, but then I doing a number of other things to help such as using Alpecin and Plantur caffeine products, as well as using a Dr Pen for coming up to a month too. So I will add an update in 2 months or so. But it hasn't done any harm and makes hair feel conditioned after using. 3 month update: I see some density improvement. but as said before i am going other treatments like using a Dr. Pen every week for past few weeks. So I'm not sure. Its not a major improvement, but its better than it was. Still not at a stage where I feel confident so dunno. Still 3 stars from me.

this is a good product and I believe it is helping restore some lost hair. the product goes on very easy, has no odor to it and is easy to leave in overnight and then wash out the following morning. will buy again.

Was skeptical but it works for me. Onto my 2nd bottle to use overnight before shampoo. My hair thinning isn't as this as it was before trying. :)

This caffeine treatment is very lightweight and does not give hair a greasy and dirty feel when used. i use it after washing my hair and i have not encountered any issues so far. that being said although i have noticed a slight reduction in hair fall the long term affects are yet to be seen. and since it is water based it might not be suitable for curly and coily hair that has been heat styled

Après deux mois d’utilisations : aucun effet, cuir chevelu sec et poisseux (incroyable mais vrai) et surtout AUCUNE REPOUSSE de plus que d’ordinaire… je n’attendais rien de ce produit, mais si vous en attendez le strict minimum vous serez déçu(e)
