The chiropractor I worked for was very diligent about researching and selling only what he felt were the highest quality vitamins and supliments. Not only did he recommend these but we couldn't keep them on stock. Parents and children alike loved them.
I have always used Ogilvie Precisely Right for my home perms. I love the way it never dries my hair out and leaves me with the perfect curl. The only exception was the time I had overcolored and did not wait long enough before perming. So always be patient if you are in a similar situation.
