It ran out so quickly that I didn't have time to figure out if it was effective, and it's way too expensive to buy every few weeks just to see if it will have any effect.

I will give 5 stars even though it is extremely expensive and runs out very quickly because I have been using it for 1 month and not a single hair falls from my head. With the recommended dosage, it doesn't even last a month.

Unfortunately, yet another Kerastase product that does exactly what it promises, and I say unfortunately because it is expensive. Along with the 8h magic night serum and the elixir ultime, there is nothing like them. On the downside, if you really use 4 pumps as recommended, it won't last even 3 weeks. I started with 4 pumps and I consider the amount excessive, I have reduced it to 2-2.5.

Excellent product, I use it after every wash and I apply the amount of a dropper to the scalp because I have oily roots. I have seen a very big difference in hair loss, lots of new hair growth. I finished the first bottle and now I will go for the second. Very nice scent as well, it doesn't bother me at all and it doesn't weigh my hair down at all with the amount I use.

It lasted 2 weeks with daily use while I was using 3 pipettes instead of 4 which is the recommended amount! I didn't see any difference in hair loss! The one from Elvive, which I have also tried, lasts longer and I saw a difference almost from the 2nd time I washed my hair! Much better and with a big difference in price

Miraculous. I have grown new hair and my hair loss has decreased significantly. I use it daily on a clean scalp, one dose at a time and not four as it says, because that's an excessive amount. I am quite satisfied with the result.

Unfortunately, it did nothing for me; the only thing it did was make my hair oily, clog my pores, and my hair still hasn't returned to normal. My dermatologist told me it will take time. Conclusion: after having been fooled countless times by ads on social media, it's all nonsense!

The scalp is visibly stronger with new hair growth.
Personally, I use it 3 times a week and I saw amazing results.
I'm going for the third bottle..

Perfect scent, quick and easy application without making your hair greasy. For daily use on clean hair, it needs a bit of massage. It's perfect!

If you have a hair loss problem, the dermatologist is the most suitable person to give you treatment. Personally, minoxidil spray and cystiphane vitamins solved the problem. This is unnecessary.

I am on my 2nd bottle, I see a difference in hair loss after about 6 weeks of using it. The truth is that I see a difference in the scalp (it looks healthier) and in how quickly my hair grows (maybe because it doesn't break?). It is an expensive product for me, but all of the above convinced me that it's worth a 2nd bottle.

It works even if you're not strict with the application, wonderful scent but once it runs out, hair loss starts again (as with all these products, of course). However, it is a bit expensive for the quantity.

2 stars for the scent. Personally, I felt my head burning when I used it those 2-3 times. First of all, it is very important for everyone to know that this particular product contains minoxidil. Minoxidil is an active ingredient that makes you happy as you see new growth and everything looks nice. However, when you stop using it, hair loss is rapid, and you really lose even the new growth you had, and good luck figuring out what to do next…. Be careful with these products because many of us have been caught out without having any serious issues…

It's not perfect... There are better products on the market that don't limit use to 6 weeks. Indeed, if you stop using it, there is an issue. However, yes, it works, it doesn't make the hair greasy and has a wonderful scent. It definitely isn't suitable for people who are sensitive to fragrances; they might find it too strong and suffocating. I would suggest you go for more herbal product lines or other "famous," low-cost cosmetic companies ("The usual" and "the ink list").

If I could put -10 stars I would!
I ordered my products from a well-known cosmetics chain, the GENESIS series (shampoo, hair mask, conditioner, and serum) as my hair is falling out after my pregnancy. I should note that my child is 7 months old and I am breastfeeding.
After my desperation, I decided to try this series. Today is Friday and I have been using it since Monday. The result is that my scalp is burned with intense itching and redness!!
I immediately visited a dermatologist and was informed that one of the ingredients is also given to people with psoriasis. I will take legal action against the company! You are simply unacceptable!!

Terrible fragrance. I gave it away because I couldn't stand the smell on my head. It made me nauseous and during the short period that I managed to wear it, I didn't notice any difference...

I used it in combination with shampoo and mask. From the first application, my hair stopped falling out. BUT it ended in 1 month and even though I continue to use the rest gradually, I see in combing that I am losing the same hair as before.

I did not see any difference in the quality of my hair. Its scent is very strong and even though I used the recommended amount, it stuck to the roots and did not dry easily. In fact, it irritated my scalp in some areas where I had dry skin.

It is difficult to absorb because its consistency is very thick. It has a strong and unpleasant smell. I apply it at night, massage it, and lie down. The smell is so strong that it stings my eyes from the fragrance and it is difficult for me to fall asleep. I would not buy it again considering that it is expensive and smells chemically.

It is wonderful, I have very oily hair and it does not make them greasy at all. I have thin hair that tends to break and it helps me a lot and the serum smells very nice. (Edit: apply the serum before drying your hair at the roots so that it can be absorbed)
