Minoxidil Itching and Aromatherapy

Hi Dr.Rass. This is my fifth question in this blog. This blog has been doing a phenominal job. Now going thru this has become one of my daily habits. Its a great job that you are doing.
Congrats Please keep it up. Now my Questions.

1. While answering my previous question regarding my itching problem with minoxidil(even with 2%) You have advised me to stop it. But I cant be bald and I want some solution for this problem . Shall I take finastride(Propecia) alone without topical minoxidil.Will I be getting any benefits out of it.Because only those two are FDA approved drugs.
2. You have written several times in this blog that topical solutions never grow new hair.(Foltene, segals solutions , procerin e.tc) Then how topical minoxidil works?
3. Please go through this web site. This has been growing popularity in India. They are saying that there is something called “aromatherapy” which contains aroma oils, a massage for 4 months grows hair back(together with saw palmetto 350 mg supplement and lase comb treatment).They are also saying shampoos should not all be used especially the one with “sulphates” but unfortunately no shampoos without sulphate is available? Can you suggest any one shampoo without sulphate (sodium lauryl or loreth)?
4. Currently my dermatologist has recommended me a tablet which contains the following “Biotin 40 mg. L-Methonine – 60 mg ans L-Cystine 100 mg” one tablet per day.Whether these vitamins and amino acids help to grow hair.She has advised me to continue for 60 days. And I also came to know that Biotin defficiency is very rare in human beings and our body recycles biotin. Is it possible for me to do any tests like blood sample to test the level of biotin in my body?

Sorry for such a big question

1. I don’t know what to tell you. If you’re itching with minoxidil, stop using it, but you run the risk of losing the benefits the medication gave you. Propecia won’t keep hair grown by minoxidil, and vice versa. Propecia works to prevent or slow down the balding in the man who has started to lose his hair.
2. I say that those topicals won’t work because they contain nothing proven to regrow hair. Minoxidil is proven to regrow hair. If those other products contain minoxidil, they’ll probably work.
3. Aromatherapy might make your bathroom smell nice, but it won’t regrow hair. Sorry, but I don’t have a clue about shampoos without sulfate. I’m not an expert on which shampoos have which ingredients.
4. A biotin deficiency would be rare, but shouldn’t you be asking your doctor about blood tests? Since you’re under the care of a doctor, I’d continue with the plan she has for you… unless you seek out a second opinion from another physician.
