I can't say that this product renews the youth of my hair, but I can say it's a wonderful leave in.
I had gone to a water park and the extreme chlorine left my hair feeling really dried out and damaged. Even my heavy duty conditioner didn't seem to make a dent in the crunchiness.
I remembered I had this little bottle and used three little dropper fulls from the sample. That totally did the trick. By the end of the day my hair was soft and bouncy again. The scent is quite nice too. It didn't leave my hands feeling greasy or over-lotioned either like some products tend to do. It's a keeper in my book.
