Took a tube with me on vacation. After two weeks in the Mexico sun, pools every day, and twisted or braided hairstyles constantly, my long hair looked fried. As in, it looked like the plastic Barbie doll hair that the mini hair brush would always get stuck in. I didn't even use the entire ampule, despite the directions instructing to. I applied about half the tube from my about halfway down my hair, combed it through, and it made the ends lay perfectly smooth like I had a fresh trim. I applied halfway down because I expected it to leave a greasy/oily residue like many deep conditioning products so, but that' never happened. Hair dried perfectly clean feeling.
I have long (approx. 40”) natural blonde wavy hair. The flyaways and dry ends are just part of everyday styling of long hair, I do not typically use heat stylers but I do condition everyday. I believe this would be a great monthly treatment for anyone with chronically dry hair.
