I usually take a multi-vitamin, and occasionally I add some type of hair supplement, usually GNC Hair Skin and Nails Vitamin’s. Well, this time I wanted to try the Program to see if that makes any difference. The program has the Hair, Skin, and Nails vitamin’s, plus Evening Primrose Oil and an Advanced Collagen Formula (that includes amino acids). The additional vitmain’s are meant to improve the skin (acne and clearing) and improve the elasticity of the hair. My new growth is currently 2 & 1/2 Inches, and I have a two month supply (thanks to BOGO) of the program, so I will update this experiment after 30, 60 and 90 days. I am going to use the program for the full 30 days as directed, then I will use my regular multi for a month and then use the program again for a total of 90 days. Then I will continue to take my multivitamin as usual,, that will more than likely take care of my extra supplement for the year, the rest of the year I will regularly take a multi-vitamin.
