Hi doctor how are you?
This is my question regarding propecia.
Most people think only DHT destroys hair but the follicles are sensitive to testosterone as well. Its interesting to note the first thing that goes on most guys is the hairline mostly the juvenile hairline which is often made up of small vellus like hairs. This is because they are sensitive to testosterone more so than DHT. And we all know finasteride lowers DHT and raises testosterone.
Can that make a persons hairline even worse by trying propecia or can propecia help maintain it? Basically is propecia good for one thing on the scalp and bad for other areas such as the hairline.
I would really appreciate if you could answer my question, because I have searched in your blog and haven’t found a clear answer when regarding testosterone and hairline balding and not DHT.
Propecia has the same impact on the frontal hair and the crown hair, but it appears that it is less effective on the frontal hair, which is often caught later after the hair loss is detectable. The crown seems to have a slower loss rate and that is probably why Propecia (finasteride) works so well in the crown. Finasteride is not bad for frontal hair and I have even seen people reverse frontal hair loss with it in the very young man, although it is rarer in the front than the crown.
For every one email I post on the site, I probably answer 10-15… and even then, I can’t get to all of them. There have been a high number of people writing in asking for my opinion on this or that, and their email usually focuses on just one thing. In some cases, what that ends up doing is raising a lot of questions for me to ask back to them so I can help get them an answer. To render an opinion and help those that email the site, I must have lots of information and sometimes even good photos (and permission to publish them is encouraged). All too often there is nothing of the sort. I don’t want to be rude by simply saying that “you” need to see a doctor, but this is not a guessing game for me and while I do want to help, reason must prevail. Bottom line… if you are writing to BaldingBlog, make your case as concise as possible with as much relevant information that you can provide. It might sound like a contradiction, but I’ll try to clarify if you need more help. I enjoy writing the blog, but I can only answer what I’ve got to work with, so keep that in mind if you don’t get the reply you were hoping for.
Common microwave oven rays should not cause hair loss, but I am not a physicist. I would like to believe common microwave ovens are safe as long as you use it as it is intended according to manufacturer’s instruction. According to the United States Department of Labor Occupational Safety and Health Administration (OSHA) microwave (MW) radiation are electromagnetic radiation in the frequency ranges 300 MHz – 300 gigahertz (GHz), respectively.
