Does what it says on the tinI tried the Kerastase Magic Duo Serum, which includes K Genesis and K Nutritive, and overall it definitely does what it’s designed to do- strengthen hair and helping to reduce hair loss.
The K Genesis serum was to stand out for me. It has a lovely, luxurious scent, absorbs really well, and never felt heavy on my hair. After using it, my hair felt noticeably smoother and silkier, with a lightweight, refined finish that felt very high-end.
The K Nutrive serum however was a very different experience .While it left my hair looking incredibly shiny and healthy, the perfumes scent was extremely overpowering and lingered for hours making it unpleasant to use, especially in the evening before bed as advised. It also left my hair feeling greasy rather than nourished which was disappointing.
That said despite the mixed Sensory experience the duo genuinely delivered the results my hair felt strong over overall and I noticed the reduction and hair loss with continued use.

Magic in a bottleThis is a game changer. My hair has never felt and looked more healthy! My hair used to fall out in masses with every wash. Now I get minimal hair loss when washing, I would say the normal amount, finally. I wake up with so much less frizz, ready to start the day. A glossy look. It looks so much more healthy.

Great duo.What a fabulous duo of haircare products.
The anti hair fall serum, applied to the scalp does appear to be improving the appearance of my super thin hair to be thicker and fuller. I had a lot of split ends prior to my last cut and now my hair is stronger and I experience a lot less breakage when drying it.
The Nutritive 8h serum smells amazing, and instantly helps improve the smoothness of my lengths. The serum applies lovely, dries in beautifully to leave soft, frizz free strands. I didn't experience any noticeable residue left behind, or any weighing down of my hair which was my main concern.
Overall its been great testing this magic duo out. It would be 5* but i think the cost of the products has to be a factor and they're on the more expensive end, however a little goes a fair way and the products do appear to be doing what they're meant to, so I could definitely justify the cost to carry on treating my hair.

Superb :)I wash my hair three to four times a week and each time I'm so shocked by the amount of hair I loose. After using the anti hair-fall serum I couldn't believe the change after a couple of weeks. It significantly improved hair loss and my hair felt stronger after 3 or so weeks. I'm stunned and really pleased with the product and will definitely be purchasing once near the end of the bottle.
Now the 8hr magic night serum is something else. I've had weak brittle hair for years and have spent a small fortune on products, however this is one of the best for results I've used.
My hair looks and feels stronger and healthier and even shinier and to top it off it smells absolutely gorgeous!!

Left my hair feeling amazing!I’ve used both for a while now. The 8h night serum was amazing and left my hair feeling super soft. I’ve used the anti hair-fall and haven’t noticed any improvement as yet but I’m going to keep at it. I thought it might make my hair feel greasy afterwards but it dries lovely and you wouldn’t notice in the morning.

Luxurious hair careI will be buying this again.
I love kerastase and these are two items I already wanted to try so I was so overjoyed to get them to review.
They were as good as I expected because I find this brand to be the highest quality results driven products.

Stunning products!This hair duo is an absolute treat for your hair. It’s a bit pricey but well worth it in my opinion! It smells beautiful, exactly like a product you would expect to be used in a salon and it feels very indulgent. On using both serums my hair feels instantly softer, smoother and a lot less frizz. Even applying overnight doesn’t leave it greasy or heavy feeling. Over time your hair feels stronger and more manageable. A win win for all hair types!

Amazing duoThe nourishing serum for dry hair smells gorgeous. A couple of pumps smoothed through the lengths of your hair instantly makes a huge difference but over time that difference remains consistent.
The anti breakage is done in sections and applied with a pipette to the scalp. There is a line on the pipette itself to help with dosage size.
Together they have improved the condition of my scalp and my hair falling out has decreased dramatically, we are now talking a few strands rather than whole clumps.
