My number one holy grail
My husband calls this product “his investment”. It’s expensive but he tells me to spend however much I need to keep a supply on hand because he loves how long and healthy it makes my bleach blonde hair.

Would Rather Eat a Rotten Red Delicious
This makes me sad... Loved it the first time I used it, but the second time, it made my hair smell like wet dog and sucked the moisture out. Can't run my fingers through my hair, no natural curls. 0/10.
