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!

Does what it says
A nice shot of hydration, smells good with a very light scent only the next day, not heady or annoying. It does make my hair softer and less frizzy. I use it even when I have a blowout, on ends and middle before sleep. The ends look refreshed and sharp in the morning.

amazing
i love this serum. i’ve struggled to find overnight treatments that don’t weigh my fine hair down and this one is fantastic. it smells great too. it’s worth the price as well, i have super long hair and i only need two pumps to hydrate what i need.

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.

It’s alright….
I usually use the Kérastase overnight serum, but I decided to try this one for a change. The formula itself may have potential, but the packaging was disappointing—the pump dispenses only a very small amount with each use, which makes application less convenient than it should be. I also wasn’t a fan of the scent, which didn’t quite work for me. I hope the brand considers improving the dispenser in future versions, as that would make a big difference in the overall experience.

Is anyone else on a full hair journey right now? I fell deep into the Abbey Yung TikTok rabbit hole and have been investigating and investing in products to repair my sun-damaged, over-processed hair. I’m even considering growing out my grey — but in the meantime I want to stop the breakage and revive my tired blonde locks. This overnight serum is amazing. The ritual alone is worth it — work this beautifully scented creamy silky serum through your hair, pop it up with a silk scrunchie, and wake up to hair that looks shiny, fresh, and smells like botanical heaven. I’m trying to avoid too much protein overload so I’m careful about what I use — this feels like pure moisture leading to happy, nourished hair. I also love how it comes in a glass bottle. There’s something so luxurious about the heavy matte glass - plastic just doesn’t give you the same experience.
