Hello Rudolphus, thank your for commenting on my suggestion. I have zero background in biology or chemistry, hence I can't argue with you academically. I can only give you the incredible success I've had. The folks that saved my hair are still in business even after 45 years, they are called Loesch Laboratory Consultants, out of Houston. But here is a huge caveat: Do not buy any of their products, as it is not needed once you realize what you need to do. Check out their original formulas, which were a very strong shampoo and a de-acidizing lotion. I used to order from them for about 3 or 4 years, about 45 years' ago, and then just started using regular shampoo, any shampoo, but the key was to never let sebum rest in the scalp. Read on their website, obviously do a search for them and you will read their take on why sebum is so bad. So my friend Rudolphus, I am returning to post here, because I felt so bad that you would maybe condemn a young kid to a lifelong of hairloss simply because I may not have gotten the chemistry question answered correctly in the exam. However, the results are 100% correct. You say the "oils" are good for the scalp, without addressing my statement that balding people have totally greasy, oily scalps full of sebum, as perhaps that should have been challenged. Would you say that people with a full head of hair for the most part, have also greasy, oily scalps, or most of theirs is dry. Why dismiss my recommendation outright, when you have not tried it? Imagine for a moment that I am correct? Look what you have done to another human being? Unless I would have tried your regimen, I would not dismiss it, who knows maybe I am right. To this poor worried mother, please, I beg you to let your son try my suggestion for 90 days at least, you are saving his hair. For a more academic answer, please read the reasons on the Loesch Laboratory website, Rudolphus, but for real results to stop hairloss, just follow my (and their advice) for free. As I mention before do not buy their products, you can just use regular shampoo, but get the sebum completely out of the scalp...oh and this is my last posting, regardless of any replies. I've been coming to these forums for so many years, I wonder if anyone listened--probably not.
