Smooths and moisturizes hair wonderfully!

I’ve been using this product for the last 3 weeks, several nights a week and I seen a noticeable difference in the texture of my hair. Typically, my ends are usually dry and frizzy (especially right after washing) but these last few weeks I’ve seen my hair become visibly softer, smoother, and less dehydrated. It smells very nice - subtle and not overpowering. I have not noticed any issues with oiliness, which usually can be an issue for me when I use oil-based products to moisturize my hair. 2-3 nights a week I just add 1-2 pumps to the ends of my hair (from ear level down, avoiding my scalp) as it is air drying after a shower. Or, if my hair is clean but already dried post-shower, then I’ll still add the product to my ends and then do a quick braid to help lock in the product. I’m also hoping this product will help with breakage, as that has been an ongoing issue for me - but I don’t think that I’ve been using the product long enough to be able to speak on if it’s helping with that issue yet. All in all, this is definitely a product that I would purchase again and would recommend to others to try if they want to make their hair hydrated, shiny, and smooth!

Bad smell imo

After returning the kerastasse youth overnight serum due to the horrible smell, I tried this one in store and thought it smelled decently so exchanged for this one. This great reviews but it did nothing for me. After trying it several days my ends and hair seemed none the better and actually felt quite dry. The smell reminded me of body odour a bit and I was reluctant to put it on clean hair and decided to return.

My new night routine!

I look forward to using this every night! I use this every day and apply on my slightly damp hair on wash day then follow up with an oil. I definitely have fine yet parched hair. I also use it on dry hair on my non wash days and love that it doesn't weigh anything down. My hair has been much softer and feels luxurious.

Miracle on curly hair

I just bought this a few days ago and can’t wait to use it every night! It truly revives my hair in seconds as I’m putting it in my hair. I have curly hair that frizzes so easily and it’s so nice to wake up with formed curls.

Smells amazing and helps with my frizz

I’ve used this for just a couple days. It helps minimize frizz without weighing down my medium/thin hair. It feels soft as soon as you apply it and still feels smooth after waking up. I’m obsessed with the scent it smells amazing.

Good

I love the smell and formula. It makes my hair soft and healthier but i dont recommend using too much if you have fine hair. I honestly didnt use it regularly but its nice! Nothing crazy tho. I also prefer the scalp serum over this one.

Expensive, Minimal Product, Mediocre Performance

For the price point, consumers should reasonably expect more product. The bottle runs out quickly, especially for those using it nightly between washes, often lasting only about a month. The lightweight texture is easy to apply, but it is ultimately a film-forming product that improves the feel and appearance of dry hair rather than providing the deeper nourishment and conditioning benefits its price point suggests. For a luxury haircare product, I would expect more than temporary softness and surface-level smoothing. The scent also lingers on the hands after application; while not overtly unpleasant, it comes across as distinctly synthetic and sharply perfumey, with an alcohol-like, artificial quality rather than anything naturally derived or refined. More broadly, I wish luxury haircare brands would move away from heavy fragrance. Added fragrance is one of the most common causes of cosmetic-related irritation and sensitization, even in individuals without pre-existing “sensitive” skin, hair, or scalp conditions. Beyond irritation, frequent exposure to fragranced formulations can contribute to cumulative sensitivity over time, making strong scent profiles feel unnecessary rather than indulgent.
