Awesome except...

[This review was collected as part of a promotion.] The best hair days are after I've used this overnight and get to wash and style, the only issue the scent is a bit much. I have a strong sense of smell which means the abundance of fragrance disrupts my sleep. I have to limit my use to days when I'm home and can do a night wash, which is sad since this does amazing things to my naturally curly, dry, highlighted strands that get a lot of heat styling. Would still recommend

Great night serum

It’s great for my dry over processed hair. It makes it soft and less frizzy and I can use it everyday if I want.

can't live without it

I've got very fine wavy hair that tends to get dry easily. This product has been a lifesaver to give my hair the extra protection at night- a quick spray of water in the morning and it looks like it has just been styled. Love it!

Good product, disappointing company practices ):

I’ve been using the Blond Absolu Sérum Cicanuit for a while now, and I have to say—it’s one of the best overnight treatments I’ve tried for blonde hair. It leaves my hair noticeably softer, smoother, and more hydrated by morning without feeling heavy or greasy. I especially love how it helps reduce frizz and keeps my ends looking healthy between washes. The texture is lightweight, and the scent is really pleasant without being overpowering. It genuinely makes my hair feel more manageable and gives it that “just left the salon” look. That said, I’ve recently made the decision to transition to fully cruelty-free beauty products, so I won’t be repurchasing. But in terms of performance, this serum absolutely delivers and has been a great addition to my routine. https://www.perplexity.ai/search/kerastase-loreal-animal-testin-WT_2FieGR5.P9m6wKn9ERg

Lightweight, Color-Safe Overnight Serum

I have compromised hair from fashion color, so I’m always cautious about trying new treatments—but this serum has been completely safe to use on my hair so far. One of my favorite things about it is the consistency: it’s lightweight and not oily at all, unlike many treatments that tend to weigh my hair down. I also really appreciate how easy it is to use thanks to the overnight feature—no need to wash it out, which makes it perfect for busy nights. I’m able to use it every night without any issues, and occasionally I’ll add a bit of oil in the morning instead when I want my hair to look extra fresh and polished. Overall, it fits seamlessly into my routine and feels effective without being heavy.

[This review was collected as part of a promotion.] I absolutely love this hair serum. It keeps my hair super hydrated and significantly reduces frizz!

Smells Nice But It’s Not Magic Night Serum!

I had previously purchased and loved the Nutritive 8H Magic Night Hair Serum, and was excited to this serum made especially for blondes. I thought it would be even more hydrating than, to make up for any damage due to bleaching and highlighting. While I enjoy the fragrance, it does not work as well as the magic serum at smoothing and hydrating the hair. If you’re looking for a much lighter alternative, then this might work better for you. I’ll be going back to to using the Nutritive serum.
