KerastaseGenesis Hair Serum | Daily Strengthening Treatment for Weak or Damaged Hair | Nourishes and Reinforces Hair | Anti-Breakage | Silicone-Free | For Weakened Hair | Serum Fortifiant

It's almost been a month and i've seen such a difference in how much hair I shed! I've been losing so much hair and tried to find solutions before trying minoxidil. I used to have a lot of hair shed on my wash days and now it went down to a couple of hair strands.Product: The serum bottle is made out of glass which is nice. There is a line on the suction stick. Each night, I fill it up to the line, dispurse it throughout my hair, and massage it into my head with a scalp massager.Smell: To me, it smells nice and not overpowering.Pros: There is noticability within the first few usages (which is nice because you don't have to wait too long to see results), easy to use, can last you up to 2 months (I still 3/4 of a bottle left).Cons: Does make your hair feel a little greesy by the 2-3rd day, cost is $60.

I received the product in perfect condition! The packaging was intact, and there were no signs of damage. Now, I truly enjoy styling my hair because this product effectively protects it from the heat and stress of constant styling. I've noticed a significant reduction in frizz and split ends, allowing my hair to remain vibrant and healthy even after frequent use of styling tools. It's made my daily routine much more enjoyable and worry-free!

I got this on a cyber Monday deal for $40 and glad I did! It smells great and doesn’t leave any residue or oiliness in my fine blonde hair. Leaves it feeling healthy and absorbs well. I use it on towel dried hair at the roots. I wish I would have bought a couple at that price.

I use this in my hair about 2-3 times a week at night. I use the dropper and fill it up and apply it about 3 droppers full throughout my scalp and massage in and let dry. I also use a microneedler I use in combination. I have seen tremendous hair growth and my stylist is shocked at how it works so well with my extensions. I am literally at almost a year and a half with the same 22” and they look like I just bought them. Highly recommend and will definitely repurchase. For anyone thinking this is watery I think you are mixing up this product and their thicker split end serum which is also amazing!! Everything from this line I am a fan if except the shampoo and conditioner it just didn’t work well for my hair and extensions.

This is a great product, BUT if you are sensitive to caffeine, do not use this at night. It keeps me up for hours.

Bought this with a full Kerastase hair treatment. This serum was to help reduce hair breakage. I use it after every hair washing. I can see a noticeable difference and am a repeat buyer. My hair feels great and looks great. This is more expensive than some others. It I highly recommend it. I love how well it works.

I ordered one and upon arrival, the package was damaged and open on the outside. I thought its okay as long as the main product on the inside is fine. I open the product and it's clearly a fake serum. There are orange smudges on the dropper and pack, it smelled of alcohol and looks very cheap and dull as a branding!

I have just discovered Kerastase and I have a few other items that I use along with this. This doesn't make my scalp feel oily or dirty. I've been using this for about a month and have noticed less hair fall.
