I use Apple cider vinegar mixed with water as a rinse after I shampoo...then I condition as normal ...But I only shampoo 1-2 times a month
I found this on it....
Add shine, bounce and remove buildup from your hair with a simple apple cider vinegar rinse. Apple cider vinegar is a well-known health food and folk remedy. Acetic acid, the main ingredient, will remove buildup from styling products and conditioners and strengthen the hair shaft, leaving you with soft, glimmering strands. Apple cider vinegar hair rinse will also balance hair's pH level, kill bacteria and is a great cure for dandruff. This rinse in not recommended for color-treated or processed hair, as acetic acid is a clarifier and can strip hair of color. (my hair is color treated but I have never had a problem with color stripping)
I don't know the cons on it..I am sure someone will weigh in...But I have had no problems
