My hairdresser recommended that I use it every night. I think it is good but I was also using other products when I washed my hair. It does not make it oily. Anyway, I believe it helped me save my hair

Excellent product, it doesn't weigh the hair down! You don't even need systematic use to see results! From the first use, the hair is softer and looks healthier! Very nice scent as well. I have used one bottle and now I'm on the second

Incredible product. I have nothing bad to say. I’ve been using it for months now. Every night before bed you apply a small amount and try to spread it everywhere, especially on the ends. The scent is divine, it’s a shame it doesn’t come as a spray so I could use it all the time haha. The next day, my hair is incredibly soft and the scent lasts. The ml might seem few but since you use a little, the bottle personally lasts me 2-3 months. You don’t need to use too much, otherwise your hair gets heavy and feels greasy. I highly recommend it.

I bought it again after countless videos on TikTok. Ok, nice scent, light texture, but nothing more.

You put it on at night and wake up with different hair. It makes them very soft and hydrated. Because I have wavy, frizzy hair, it has saved me—I love it!

I can't say that I am particularly satisfied. I haven't seen any significant difference and I have been using it for almost 2 months every night. I feel like it weighs my hair down when I apply it. However, it smells very nice. I don't think I would buy it again.

It makes the hair very soft and light, smells amazing! I have a lot of very long hair, 3 pumps are enough and it is the best I have tried so far!

It is wonderful, it smells fantastic
It makes them instantly very soft!!
It has fixed the dry ends of my hair in combination with other products, oils, and masks!
I will definitely buy it again!

A product on its own cannot work miracles; it needs a complete care routine and always according to the needs of the hair. I have dry hair after dyes and highlights, it frizzes easily and is unruly. This product helped my hair stay smooth, hydrated, and grow without breaking. I love its texture and scent, but I don't know if it helped me on its own because I also use other products like leave-in conditioner and oil from another brand.

Perhaps one of the best products from Kerastase that I have tried, I bought it when I did highlights for the second time, applying it 3 times a week, it really leaves the hair softer, healthier, and shinier. However, if someone has relatively healthy hair, it might not do much and could even have the opposite effects, so I would say be careful. If someone is looking to spend a little extra money on a hair product, I believe this is a good choice.

Nothing special, I've already used up half the bottle, it might do something but there isn't much of a difference at least on my hair, blonde with highlights, long and dry at the ends due to bleaching

Amazing product, it makes the hair smooth and smells wonderful. It is not for everyday use, especially if you have fine hair. The 4 stars are because of the price

My hair got dehydrated! Really a waste of money!
It became a trend everywhere but it's not for damaged hair. No way! 0/10

It really does what it promises, but its price is a bit high. I will buy it again though because I am very satisfied

Very good product, moisturizes and nourishes the hair. The next morning, the hair is like silk, without feeling heavy at all. Expensive, yes, but worth it

Miraculous girls! My ends were like straw and after a palm's worth cut and applying this magical serum every night for 1 month that I've had it, it's literally silk!!! I would pay even more money for what it does!!!

Very good product although the price is a bit steep. As time went by, the feeling in my hair in the morning got better and better

It does exactly what it promises. My hair is very damaged from bleaching and dry. It makes it silky, soft, and doesn't weigh it down or make it greasy. It is expensive but worth it

It is a good product, nourishes the hair and leaves it soft. However, to do its job, you need to use three pumps every night (otherwise, personally, I don't see a difference). Therefore, my bottle lasted 1.5-2 months and it is a very expensive product. The only reason I would consider buying it again

In the first few days, I didn't see any difference in the morning, but when you apply it, it really leaves a very silky feeling and has an excellent scent. Now that I've finished the bottle (I bought it in July, it's December, and I use about a pea-sized amount on my long straight hair 2-3 times a week), I realize that it has helped a lot to keep my hair moisturized and my ends from breaking. I will definitely buy it again.

Excellent product that helps hair stay soft and the ends moisturized. Personally, I have long straight hair and this product helps.

Incredible product. I didn't realize it at first, but now I can't live without this serum. On wet hair, however, it doesn't "sit" very nicely; it's better to apply it on dry hair. (If I put it on at night, it also creates nice curls that last). It doesn't frizz, it doesn't stick

Very good and effective hair serum. It moisturizes and functions like a mask during sleep. It smells perfect.

First of all, I had heard very good comments from many girls about the following product. In my own hair, however (very curly and thick), it didn't do anything special. I suppose it can work wonders on different hair types.
P.S. It smells AMAZING.

I bought it from a hair salon. Unfortunately, I didn't see any difference in my hair. I bought it in January and have been using it daily until today, just to finish it because I paid a lot for it.

Lightweight serum that doesn't weigh down the hair, smooths the strands, and adds shine. It has a wonderful scent. Although it claims to be suitable for dry hair, it is equally good for oily hair.

Awesome, my hair became super soft and moisturized. I highly recommend it. 3 pumps are enough for medium hair.

Very nice product. My hair is straight. I use it once between shampoos. It requires a small amount.

With 4 applications, my hair (dyed, thin, dry) appears more hydrated, but it requires a good amount of serum to go through all the hair. Along with the serum, I use the elixir oil and the Apivita mask.

It spreads very difficultly on the hair, it contains alcohol and it made them sticky and dehydrated. Despite all my efforts to give it a chance, I found it from indifferent to bad. What can I say, maybe it doesn't suit all hair types; it definitely didn't work for mine.
