Absolutely fantastic — I just wish there was more!
I am absolutely in love with this product. As someone who gets their hair lightened at at least 2-3 times a year, and spends the entirety of their summers lifeguarding in intense sun exposure and chlorine, there is often a lot of issues to fix in regards to my hair. So when I tried this product and it smoothed all of my frizz, saved my dry, brittle ends, took my hair from dull to shiny and bouncy, and protected my hair from further breakage, I was completely sold. As I continued to use this product, however, I discovered that its only negative attribute is the quantity inside the bottle. I have read other reviews saying one bottle hardly lasted them a month, but i’ve had this product for TWO WEEKS, using 2 pumps at most after each wash due to the thickness of my hair, and it is already running out! The dual pump is a cool feature, and it definitely works, but it takes away from the practicality of the design and customers getting what they pay for. Absolutely fabulous product, but $50 for only two weeks of perfect hair? You be the judge!

This is a 5 star product in a 1 star bottle
I love this serum. However I can see that I still have SO much left in the bottle sbd can’t get ANY more out. The packaging is annoying , getting it to stand up straight on my vanity was annoying and now I’m wasting half of this 50 dollar product.

Not worth it
Smells amazing but didn’t notice the product doing anything for my hair. Another downside is that it’s very pricey for such a tiny amount of product.

If you bleach use this!
My hair is bleached every 4-6 weeks and this product leaves my hair ready for blow dry and heat styling. As an actor, my hair goes through rigorous styling damage. After one week of using resistance hair serum my stylist commented that the structure of the hair seemed improved. My hair is no longer straw like it is flexible and shiny.

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.
