Do you have a problem with dandruff? Try the Apple Cider Vinegar (ACV) rinse. I have had dandruff issues since I was a little girl. No matter what shampoo or hair food I used, the flakes used to always return in no less than a week. I have used most of the shampoos including medicated ones some after being prescribed by my doctor trying to get rid of this problem to no avail. Greasing my scalp with most of the hair foods which claim to help with dandruff only made my condition worse and got my scalp so itchy I would scratch all day until I hurt myself from all the scratching.
