I had Dandruff as long as I can remember and have used "Head and Shoulders" for at least 25 years. One morning a few weeks ago, I ran out of shampoo and started using my wife's un-medicated kind. I keep a bottle of colloidal silver on my bathroom counter to take a swig from each morning. It has a spray cap on it so I can use it as deodorant (works great!). I sprayed it on my hair and let it dry. I noticed the next day, my hair was nice and soft. I did it the next day and used the un-medicated shampoo again. Now, I use it every day and have soft hair and no itchy scalp or dandruff. What a blessing! Try it. It may work for you.
