Resistance - Sérum Thérapiste

What a wonderful fragrance! I have all the products from this line. The unique packaging features a transparent and white color. My hair is soft, shiny, and smells lovely. I highly recommend!

Must have when humid/rainy , great in all weather!

I've used this since before it was named Resistance Hair Serum (used to be Fibre Architect), so obviously a long term fan! Not in love with the packaging, sometimes pumps unevenly, but never had a problem replacing it for one that worked, and only had one really problematic bottle over 15 yrs, so really splitting hairs (pun intended) as this product protects root to tip in styling, and I use a flatiron regularly for styling, but I've yet to find any other product that protects and holds its sleek style from EXTREME humidity and heat, even after getting my hair half soaked during a dental procedure, my hair looked as good going into the office as it had when I left, so it has serious staying power. A TINY bit goes a long way and it has a great scent.

A must have in my routine, I really recommend.

From the first day I started using the product I could see the difference in my hair…! I have bleached and dry hair … after applying the serum it’s feel soft and moisture…!!!

Meilleur serum

Au bout de 2 semaines les pointes sont douces !! Genial je recommande, le seul bémol le prix.

Disappointed

I bought this product because is for really damage hair , because of my highlights but I really disappointed because doesn’t do anything for my hair , only made my hair smells good nothing else . So is no for me .

I love this product, I have been using it for month and to me is the best for dry blonde hair, my hair now is bright, no damage at all. I recommend 100%. I actually use all kerastase products

Great product if you can afford it

This product is fantastic and has made my hair feel amazing. I’ve been using it for a month now, along with the shampoo and conditioner from the same line, and I’ve already noticed a significant difference. Unlike many others who’ve complained about the pump, I haven’t had any issues. Both sides of the product have dispensed smoothly. However, I do find that it goes quite quickly, which is a bit frustrating considering the price. For reference, I wash my hair every other day and use the product after every wash. I’m almost halfway through my bottle. If you can afford to replace it regularly, this product is truly remarkable.

Working wonders for me!

I bought this because my stylist told me it will help with the breakage from bleaching my hair (previous stylist left me under the dryer for too long) and after just a few weeks my stylist has seen significant improvement! I'm not a huge fan of the scents of Kerastase, little too florally for me, but I do like this product.

Good!!!

So far so good helps with dry brittle hair I love it . A bit pricey but I I’ll be checking out there other products .

Great product, horrible packaging

love love love the product but hate the packaging! Each time I've gotten this it feels like I'm throwing away half the bottle b/c one side is still relatively full but the other side is empty and hence nothing more comes out. Even if I could take off the lid to get the rest I'd be somewhat happy, but you can't. That kills me.

WORTH YOUR MONEY!!!

SOOOO GOOD IT HELPS SO MUCH AND PROBS BEST PRODUCT IVE EVER HAD

Damage who? I don’t know her.

This serum saved my hair. Postpartum hair loss, damage from heat styling, damage from years of colouring- my hair wouldn’t grow and kept breaking off. I was desperate. My last trip to the salon and my stylist was so impressed with the health of my hair! Wil never go without it from now on.
