I am usually such a slacker when it comes to leaving reviews on Amazon, but after using this product for the first time last night, I felt compelled to give this serum a glowing review. In fact, I have already subscribed to receive it every 2 months. In hindsight, I think I will have to change that to every month. I have problematic thick, frizzy, and “bendy” hair; not straight enough look nice when I air dry, nor curly enough to scrunch it into nice curls. I, throughout my life (I am in my 60’s), have literally tried at least 50 brands of serum, and nothing I have ever used has even come close to this product. I have traditionally worn my hair about shoulder length, and in the last year or two have been getting it cut shorter and shorter due to the fact that it has been becoming harder to manage my regular length. For you girls out there who are wondering about what shampoos and conditioners I have tried, or now use, this is the rundown: I used to love the old formula of Pure Grace shampoo and conditioner, and when used with Philosophy’s (now discontinued, of course) serum, I would say that that combination came the closest to perfect. Then I tried Wen. I have been using Wen for about 5 years now, and I found that using the cleanser, then the oils on wet hair before blow drying gave me ok, but not perfect results. My hair may have looked semi-decent after styling, but the minute I stepped outside in the humidity, it would puff up and start to look dull and feel coarse. I received my Cosmocap serum yesterday afternoon, washed my hair with Wen, applied a dropperful of oil on the lower half of my hair (seems like a lot, but my hair is really thick), then applied the Cosmocap. I could not believe how silky and soft my hair felt, even while it was wet. Then, after blow drying, I knew I had found the Holy Grail of all hair serums! Not only did my hair feel different, but it was bouncy and straight, something which I have been wishing would happen with each brand/system/product I had spent lots of money on, but never achieved my seemingly unattainable goal until now. I only mention the shampoos to assure you ladies who use Wen that you can, indeed, use other stuff with it to enhance your hair, no matter what claims are made about the product, like “it is the only thing you need to make your hair great”. Try Cosmocap with any cleansing products you usually use, and the results will be unbelievable. When I ordered my Cosmocap, I thought it a little pricey, but I bought it due to all of the great reviews. Now I realize that using this serum will actually save me money; no more blind purchases of shampoo, conditioner and serum that seem promising but always disappoint. Now I can use up even the $$cleansers that I was considering giving away, and the Cosmocap serum will ensure that my hair looks great. I never want to be without this stuff!

Love this Like Magic Hair Potion
First off I have very straight hair and, as a stylist once told me, although I have a lot of hair the actual individual strands are very thin. I have to therefore be very careful of using certain products because they will make my hair very greasy and weighed down looking. I wanted this particular product because of the amazing sounding hair nutrients and nutrition in it. I also think the packaging is super cute (a clear glass bottle with a cork top, and the little twist off aqua colored single use capsules) I was afraid at first that this stuff would make my hair a greasy mess. Let me tell you though, I threw caution to the wind the first time I used this and put it in my dry clean hair. Miraculously, and literally like magic, it did not make my hair at all weighed down or greasy. In fact it was like it went double the volume and shine instantaneously. Plus the scent is absolutely heavenly. It is not overpowering, it’s intoxicatingly beautiful and almost naturally therapeutic almost like high quality essential oils are. I don’t like heavy perfumes and most shampoos but this scent is so nice! In fact, if this scent were a perfume I would buy it! I have been using this about once a week, and my hair has been thicker, healthier, shinier, softer, and best of all it has been shedding less and less. I love this product and definitely will reorder!

From a Hairstylist’s Perspective
Overall I would say I like & recommend this product! I’m a licensed cosmetologist so I’m definitely more of a critic when it comes to hair products... What I like: safe ingredients, nice scent, portability, softness, less-waste, main packaging is cute, shortens blow dry time What I don’t like: potential oily feeling, can be too heavy for some hair types (doesn’t add volume), packaging isn’t always consistent You can most definitely over-use this if you’re not careful. If you have fine to normal hair, I would recommend even less than what their description says. After about two months of use on my own naturally fine curly hair, I can tell that a little goes a long way. Every person is different, so just be cautious of what works for you! They do quote that it adds volume, but I did not experience that. Even with a light amount it seemed to weigh my hair down some, which is to be expected with an oil. I do have fine hair though, so not all may feel that way. I noticed some of their packaging on their Instagram looked very cute straight out of the mail...I received a typical Amazon envelope with just the jar inside. It doesn’t bother me, but it is important to keep in mind if you’re expecting a grandiose unpacking experience like some pictures show. That all being said- I feel as though it does add shine and seems to keep your hair healthy. Just use the right amount and take it slow. Since it does contain keratin, you can over-use it, so I like to apply it every other or 3 times after shampooing. Hope this helps!

Didn't do what I needed
I got this specifically to help the static issue I have been having badly with my hair. I've used twice so far. I applied to damp clean hair and the first time it did seem to help. However, the next time it did not. It is easy to apply and move through hair. It does seem to absorb well. I did research on serums or products with Dimethiconol. It's a silicone which can cause build up and prevent moisture. Since my issues are due to lack of moisture this is not helpful to me. Does seem to give my hair more texture and softness but it was more noticeable the first time I used it. I will not buy again because of the dimethiconol.

Smooth, shiny, and strong
I've never been one to take great care of my hair. Shampoo and conditioner is about all I ever use, no additional products. However, lately I've been wanting to get more into hair care because who doesn't want shiny, strong hair? I was so excited to try these Remilia serum capsules because one, look at the packaging, it's adorable. And then, the benefits of shine, strength, and moisture. All things my hair could use more of. All you do is twist the little top off the capsule and squeeze the serum onto your hair. According to Remilia, you should apply half to damp hair, and then the rest after if needing frizz control and extra shine. The first time I used a capsule, I applied it to damp, brushed hair. With me having pretty short hair (a bob), I had plenty left over (they definitely give a generous amount per capsule!). After drying, my hair felt extremely smooth and soft and the ends did seem less frizzy. I think I noticed the biggest difference though when I applied the serum onto dry hair. After allowing the serum to soak in, my hair felt silky smooth without any frizz. It also had a nice shine to it as well without looking greasy. . One of my favorite things about Remilia Hair capsules though is the smell! It's such a nice, light scent that makes my hair smell amazing! Another thing, I left this serum on my hands for a little bit and I couldn't believe how soft they felt. Which is quite a feat with how dry and cracked my skin is right now. So maybe they can turn this hair product into a body oil/lotion as well (hint hint :D)?? Also, these are cruelty free and the capsules are biodegradable!

My hair is so soft & shiny!
This is my new favorite serum, look at how soft and shiny it made my hair! I will say the formula can be kind of heavy on dry hair. I would only apply it to wet hair and REALLY work it in to the ends well. The capsule seems to be the perfect amount for my hair which is short and fine, but I could potentially see needing to use more if you have insanely thick hair. Definitely start with one before deciding to use two because it does go a long way! I like to brush mine through to make it evenly distributed so my hair can really soak it in. My hair looked like this after right after blowing it dry! No straightener or any other products were used. My hair wasn’t tangled, greasy or frizzy and it smelled AMAZING. I’m working on getting my bleached hair healthy again and this is a perfect addition to my hair care in order to meet that goal!

Hair looks smoother and less frizzy after one use, no greasy feeling!
Thank you Remilia hair for gifting me this item! MY FIRST IMPRESSIONS: you get a good bit of serum in each capsule and they are so fun to pop open! I definitely feel like my hair is smoother and less frizzy after using. I also enjoy that my hair doesn't feel/look greasy (an issue with other serums). I'm excited to keep using this and see the long-term differences. I will definitely be adding this into my hair routine. My main issue with serums in the past have been that they leave my hair looking greasy or dirty. These one absorbed so nicely! I definitely recommend flipping your hair and applying it that way if you have thicker hair so you don't have to use two capsules. I applied mine without doing that at first and ended up having to use another capsule because I didn't spread it fast enough.

Hair Magick in a bottle.
I Bought this product for my Daughter & myself. I have fine straight long hair. My daughter has Curly thick hair she is growing out. My daughter uses them once every 2 weeks & I use them about once a month . We both love how they make our hair look/ feel . Soft, silky, shiny , bouncy. Not too thick for my thin hair it actually gives me some volume the first couple of day after use . I use half a capsule my daughter uses a full capsule . We do not use everyday or more than I have posted as too much keratin can cause breakage . Finding the right balance for our hair to use & this stuff is amazing . My mother is now ordering for her very thick long Italian hair after seeing our hair after treatment & over all improvement in dryness & shine. Just remember, a little goes along ways . The fragrance is not over powering to me , but if you are easily irritated by fragrance this may be problematic for you . Both myself & my daughter have not experienced any irritation. Also :Dimethicone is sometimes referred to as a silicone oil. Dimethicone coats hair, providing great shine and conditioning to the hair ....A Simple clarifying shampoo once a month prevents build up even if you are using no silicone oils , at least for myself and daughter this has worked fine. We also get trims every 2 months or so . I Will be a repeated customer and be repurchasing .

High quality product at a great price.
So let’s first talk about the benefits. This product is clinically test, cruelty free, plant based, bio- degradable and are gluten free. That’s already a win for me! Their key ingredients are ProVitamin B5 to strengthen the hair, Keratin Amino Acids for repair, and Silk Hydrolysate for hydration. It is used to repair damaged hair, tame frizz, stimulate growth, protect from heat and add volume & shine. . . . So far I’ve checked off 3 out of 5 benefits. It’s only been a week and so I’m still waiting to see the repair to damaged hair as well as hair growth. I wash my hair every other day and I’ve been applying this serum to the length of it after every wash. I also use it on dry hair before styling. You guys, this stuff smells really pretty! The scent is subtle, not over powering at all. Each capsule comes with more than enough product. I have super long thick hair and one capsule is just perfect. It leaves my hair so soft and smooth afterwards. I’ve noticed a dramatic reduction in frizz. And I can really see the shine especially after straightening. This is a high quality product at such a great price. This bottle will last me well over a month. Overall, great product and the packaging is so aesthetically pleasing that it has quickly earned its way to my heart and a spot on my Shelfie. 🤗

Shine and Softness!
I have been struggling with frizzy hair eversince I have been spending more time outdoors playing golf. The Remilia Hair Serum and Hair Mask is proving to be a game changer for me. I have only been using it for over 3 weeks and I can definitely see the difference. The innovative capsule design for the serum is a stroke of brilliance. Not only is it convenient, but it also effectively tackles the frizz without leaving my hair greasy or heavy. I'm impressed with the natural shine and softness it gives my hair. As for the hair mask, it's become a delightful part of my in-home spa regimen. Both products smell amazing! One aspect of Remilia Hair products that stands out to me is their commitment to being cruelty-free and not conducting animal testing. This aligns with my values and adds to the overall appeal of the brand. I am excited to see more progress and I continue to use both the serum and hair mask.

In addition, they have a delicious aroma that remains in the hair for hours. My hair looks healthier and is much easier to comb. I would definitely buy them again.

This stuff works. Buy it if your hair is thinning or falling out
I have been using this for about 6 months. It works great. Moisturizes my scalp. Regrew hair in an area that was constantly being scratched due to scalp issue and helped heal the scalp if a 2 year issue even the dermatologist couldn’t fix. Then I noticed at the temple area where I typically have very fine hair that never grows, after 6 months I now have 4 inch long thicker hair there. I have never had complements in my hair because when it gets long it gets stringy. Evans’s so much of my hair falls out due to hadhimotos. After 6 months all I get are compliments on how beautiful my hair is and I have been able to grow it out long and keep thicker hair, even styling and using heated tools.

Great
👋🏻 Heyhey! Happy Sunday! Haircare is a hot topic this year and I want to help my minion friend here who is trying to get more hair/healthier hair. So I told him to plunge into the serum I’ve been using. @remiliahair Remilia Keratin Hair Treatment. It can be bought on Amazon for $23.95 for 30 capsules. It claims to contain Vitamin B5 & Amino Acids for dry, damaged hair of all types with benefits of deep conditioning repair and anti frizz (color safe and sulfate free). Safe as daily treatment for stronger, healthier and fuller hair. It also claims to have thermal protection! I have long hair and one capsule is more than enough. To be honest, I didn’t think one capsule would be enough but it contained more product than I imagined. It feels like silicone and silky on my fingers and once on my hair I absolutely love how it helped tamed my hair! My hair usually gets tangly the morning I wake up and this helped with frizz and tangle giving my hair the fresh washed hair look especially important for the ends of my hair. It definitely assisted with combing out my hair too! I did notice a slight volumizing effect but my focus was to make my split ends look healthier since my shampoo and conditioner already helps with volume. These capsules are bio-degradable and vegan and best of all, they do not test on animals. In addition, these are made in Italy and formulated without sulfates, parabens, alcohol or harsh chemicals. *gifted but opinions are my own #MeTime #beauty #instabeauty #asianbeauty #instareview #love #bblogger #beautiful #instagood #instadaily #bblog #instalike #instamood #instamoment #skincare #likeforlike #sensitive #nontoxic #luxury #haircare #hairgoals #cleanbeauty #skincareaddict #investment #skincare4days #discoverunder2k #skincarecommunity #abcommunity #green #cutel

Great for fine hair and hair with texture
I had this in my cart for months after seeing a review on social media, but the price scared me. I finally gave in and bought it and am so glad. I have thick fine hair, but my new growth is textured and out of control. We also live in a dry climate with hard water so the hair suffers. This stuff is amazing. It does not make my hair greasy/oily and it gives it just the right amount of moisture and sheen. There is a light fragrance that is barely there and it is nice. If you are on the fence give it a try.

Love the concept!!!
At first I didn’t think that one capsule would hold enough product for my hair because they look so small, but one is actually the perfect amount for my hair. They are meant to be used with wet and dry hair. I prefer using leave in treatments like this on wet hair. It wasn’t sticky at all and absorbed really nicely into my hair. When my hair was completely dried, it felt silky smooth. This definitely out-performed some of my other leave-in products in terms of taming frizz. I feel like if you were to use this on dry hair, it would just weigh down your hair because there’s a lot of product. There’s also the issue of people that don’t have short hair; this may a little too much product and you can’t really close the capsule if you don’t want to use all of it at once. The little blue capsule is also biodegradable, so no worries about it going to waste.They’re also great for traveling! Overall, I like these and I think it’s a cute concept (very instagrammable) but I do think they are a little expensive for everyday use because one bottle has 30 capsules and costs $24.

Toxic ingredients!!!
Highly toxic. The number one ingredient, Cyclopentasiloxane, is associated with reproductive toxicity and considered a substance of very high concern by the European Chemicals Agency for being persistent, bioaccumulative, and toxic. It is restricted in the EU under REACH regulations. Cyclopentasiloxane may contain the impurity cyclotetrasiloxane which is a reproductive toxin. Furthermore, the ingredient Cyclomethicone is a generic term for cyclic siloxane materials such as cyclopentasiloxane and cyclotetrasiloxane which are used in cosmetics but are known reproductive toxins and endocrine disruptors considered substances of very high concern by the European Chemicals Agency for being bioaccumulative and toxic. AVOID!
