Nice overnight serum

Thanks to the Stellar Product Testing Panel for providing me with this hair care item. I have never used an overnight hair serum and I’m happy to have tried this one. It feels very nice and soft going into hair. It was easy to apply and the bottle having a pump helps a lot. I noticed the morning after using the serum it was easier to brush my hair and my hair felt nice and soft. My hair felt smoother and I feel like it had less frizz. It was easy to incorporate into my nighttime routine. I was scared it would make my hair greasy but it did not and I was so happy. Overall I was most impressed by how much smoother and healthier my hair looked. I have natural waves and the frizz can sometimes be out of control in the morning and I feel like it helped tame that. Only reason I gave it a 4/5 is because it smells nice but the scent is a bit strong when you first put it on. It eventually dies down but other than that it’s a nice overnight serum.

Easy to use and smells amazing

As my title says, this serum is super easy to use and it smells amazing. To start with the use, it is a thicker serum- it almost reminds me more of a leave in conditioner than what I usually think of as a serum. The thickness did result in me not having much come out of the spout at first (I would have to press the spout 7 or 8 times to get a pea sized amount) but once I took the lid off, and then reinserted it, it fixed the issue and now I get a pea sized amount with just 1 press. Now that its coming out easily, its super quick to apply to my hair at night. I have fairly long hair, its almost to my waist, and I only need like 5 to 7 spritz's to get enough for my hair. It spreads through the hair really easily, and seems to easily coat it evenly. It also absorbs pretty quickly so I haven't had any instances of it leaving residue on my pillow or anything. The smell though is my favorite part- yup, even more than the silky, magical feel in the morning. It smells heavenly! I'm decently sensitive to chemical smells and this doesn't smell like chemical AT ALL. Its hard to describe, but its genuinely enjoyable. My husband also commented on how nice my hair smelled at night. All in all, this is a win for my routine! Thanks to the Stellar Product Testing Panel for sending me this to try.

Love it but can't wait to see how it is over time!

I've been using the hair serum before bed on my dry hair 2-3 times a week for the last month after receiving it from the Stellar Product Testing Panel. I have been dying, highlighting, and straightening my hair for 20 years and after having my son, it was pretty well smoked. I need to use this product longer to see significant results on my fairly damaged hair but so far, I like the direction its going! There's definitely less frizz and it feels softer but I'd like to see if there was more significant repair after a longer stretch of use. I'm not great at beauty routines so I keep this one on my nightstand so I remember to put it in my hair before bed, which has really helped. My dream of all dreams is that this helps repair my hair in the long run, but for now, I appreciate how easy it is to use, how light and non-greasy it feels, and how well it incorporated into my routine.

Stellar for curly hair!

I was lucky enough to receive this serum from the stellar review panel. I normally wear my hair curly, but decided to give it a whirl to wear my hair straight. I thought it was incredibly easy to put the serum in before bed and the smell was great to boot! After putting it in for about two weeks, I definitely noticed that when I wore my hair curly it was smoother and easier to condition.

Different hair product with different results

I was given this hair care item to try as part of the Stellar Product Testing Panel. I was very skeptical about the idea of putting this on my dry hair at night, because my hair easily starts looking greasy from product. First, I love the smell. It smells like a really expensive hotel that has it's own scent that you want to buy a candle of to take home. The scent is definitely gone from my hair by the next morning, which is nice since that keeps it from competing with my perfume. It is easy and quick to put in my hair at night - just takes a few seconds. The biggest thing I've noticed is that when I first wake up in the morning my hair looks much closer to "ready to go." It looks less frizzy than is normal for me in the morning (I live in a really humid climate) and less crazy and all over the place. I have just been running a brush through it and going rather than styling. I can't say that I have noticed any long-term changes to my hair at this point. I'm not sure if that will come as I use it longer (been using about 2 weeks so far). The instructions said to use 2-3 nights a week, and I can also say I don't see any effect on the nights I don't use it.

So good

Where has this stuff been all my life?! I have bleached hair with ends that get straw-like after wash day, and two young kids so I don't have time to wash my hair too often. I LOVE that this product is applied on dry hair and doesn't need to be washed out so I can use it even when a shower isn't in the cards. It does seem to make my hair silkier and lets me wear my hair down when usually I'd just put it in a bun because the ends look frizzy. The scent is also great and smells like an expensive vacation. Would recommend! I received this product through the Stellar Product Testing Panel but will rebuy myself when it's gone.

Breaking up with breakage

This product completely solved my breakage problem. While it does not “repair” already broken strands, it prevents the breakage from going up the hair shaft, and I have no new breakage since using this product continually. I also have never really been able to grow my hair long since I have struggled with breakage, and thanks to this product, I can now do that!

This works for fine dry hair!

I have been using the overnight serum every night for the last 3 months and I genuinely love how hydrated my hair feels the next day. The consistency is perfect for all hair types- I have long fine curly hair with dry ends and typically use four pymos.

Softer, sleeker hair

This hair serum is meant to be used on dry hair and left in overnight, not rinsed out. It has a sweet floral scent and a rich, creamy texture. The bottle is heavy and luxe (just don’t drop it)! While I don’t see a huge difference, I do feel it: my thick, dry hair is softer and more manageable after use. I also notice fewer flyaways when I put my hair in a ponytail or bun.
