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.
