Lisa: Thank you so much for your reply. I am fairly certian that my problem is related to allergies to hair color b/c I have checked out ok on everything else. I am 35 and in very good health. If I figure this out I will certainly let everyone know my solution. The next time I color my hair I will have my colorist use your products. I am glad that you have worked so hard to create this alternative. Thanks again, M.Moore
