Loved this hair serum! I have a lot of hair, but it's really fine and most products weigh my hair down. This was the perfect amount to deep frizz and really smooth my hair.
I love how lightweight yet nourishing this serum is. It leaves my hair smooth, shiny, and frizz-free without feeling greasy. Definitely a must-have in my daily routine!✨
I just got this product, it's really great and kind to my hair, I really love it.
A luxe wellness retreat for your hair! Cosmocap daily hair serum gives your locks unbelievable shine and softness, with added UV protection (Polysilicone-15: UV filter/silicone-based sunscreen agent). The texture is a clear, silky oil-gel that absorbs into the hair and provides frizz control and weightless shine. If the show stopping results weren't enough, the spa-like scent could get you hooked alone! (Cedarwood/vanilla/jasmine/rose).
As someone with extremely frizzy hair this has saved me! It smells amazing, easy to apply, and the container is SO cute!! 10/10 recommend
Absolutely obsessed with these little capsules! My hair feels silky, looks shiny, and the frizz is completely under control—even on humid days. I use one after every wash and it instantly smooths my ends without weighing anything down. Plus, the packaging is super cute and travel-friendly. I’ve tried a lot of serums, but this one really gives salon results at home. Definitely a new staple in my routine!
I love these capsules! I leave my hair soft, smooth and smelling amazing. The packaging is elegant and they are great to take them with you while you are on the go.
I am absolutely thrilled with these capsules! From the moment I received them, I was impressed by their incredibly aesthetic appearance - the color combination of the packaging is so beautiful and elegant, it truly stands out on my shelf. But what I love most about these capsules is that they are completely non-greasy! After using them, my hair never feels oily or weighed down like it sometimes does after using hair oils. Instead, my hair feels light, soft, and looks shiny and healthy. Another amazing feature is the scent - it’s wonderful and leaves my hair smelling fresh all day. I am genuinely very satisfied with this product and would highly recommend it to anyone looking for an effective and pleasant hair serum!
The products are magical, the serum is restorative with a rich aroma and is one of my favorites.
I absolutely love the hair serum, it's so easy to use and it also serves as heat protection!

The CosmoCap is perfect for controlling frizz and hydrating your ends. I apply after a shower while my hair is damp, not completely wet. Each cap is the perfect amount for my hair - I have long, thick, hair that goes down my back. It smells wonderful and leaves my ends feeling refreshed.
The serum is incredible, it left my hair very shiny and hydrated. I didn't need to use a straightener because it looked beautiful, so I will continue using it and won't remove it from my hair care routine.🫶🏻
Love these! They really make a difference in my hair!
It smells super good, it made my hair soft and I don't have frizz, thank you 🥰
This product is excellent. It adds a lot of shine to the hair without weighing it down, and it has a pleasant scent. I absolutely loved it.
I get a lot of compliments My hairdresser always asks what I’m using every time I put remilia caps on my hair. After I use them my hair ir shiny and healthier. I use half of it on wet hair, then style it.
Hair mask and oil The packaging is very aesthetic:heart_eyes: Pleasant aroma and texture. I’ve used it three times, but I can already see tangible results! :heart_eyes:
Will absolutely buy again My hair has never been so soft and shiny. It's crazy. Only 4 stars because the ingredients aren't so good, but whatever
love!!!! love this!!! i’ve been putting it everyday in my hair the past few days and love it! i thought the capsules would be difficult and messy to pop at first glance, but it’s actually very easy and very clean. i love the caps and love the results with my curls!
luxury hair capsules !! Wow this products is amazing - I have super curly dry colour treated hair so it can be hard at times to find effective haircare products that actually work, and this sure does!!! left my hair feeling healthy, silky and shiny! Will use again after my bottle is done for sure
Absolutely Amazing I’m in love with this hair serum. It was really easy to use. Spread half the capsule from the ends up when your hair is wet and the rest when your hair is dry. This is is my hair after only 2 applications. It is noticeably smoother and the ends which were in really bad shape look totally different. It also has been raining on and off all day in this photo and I has been out in it quite a bit and I am amazed at how little frizz that’s been happening. I also have no other product in my hair than normal washing. So I think that says a lot.
Love it! I really like this product, each capsule has more than enough to completely cover my hair leaving it smooth, shiny and helping get rid of any frizz. I’ve definitely noticed my hair especially my ends looking better and not as dry as usual after using this product plus it also smells good.
I can only say this GET IT ….I have not only cut time from blow drying my hair I have only used this product 1 week every other day …my hair never looked and styled better ….!! Must have with your glam essentials.
Does not work any better than any other serum. But atleast the capsules are fun....
