Love it but fragrance..
Love this product! I’ve used it for a month now and my hair looks so much healthier: less frizz, shinier but not oily. Note: while the rec is 3 drops I use 6 and my hair is above shoulder height. My only real issue is the fragrance. Smells ok not strong but it is NOT a clean ingredient. Unfortunately that makes this a product that isn’t an option for people who want to stick to a cleaner lifestyle. While I love it I won’t be repurchasing.

Couldn't maintain a healthy blonde without it
I have very long, icy bleach blonde hair but am naturally a mousy brown. Since using this daily for a few months my hair is thicker and longer because of less breakage. I'm on my 3rd repurchase and seriously would not be able to be as blonde as I am, with hair as healthy and long as it is without this. I run it through the ends of my hair almost daily.
