This may shed some light. I emailed Dr. Proctar awhile back and here are his responses.
Hi there -
I am a 31 year old man who is using Propecia. That is all I am using at this time and am thinking about cutting my dosage from everyday to every other day. I also want to try other products to compliment the Propecia. I came across your 2 products and was very interested. I had a few questions I hope you can answer before I use this product.
1) I am reluctant to try minoxidol because of it's shedding reputation. I am afraid at my age that if the hair sheds to badly it wont grow back.
It does not work like this. The shedding is caused by new hair starting to grow. Everything that brings follicles out of dormancy can cause loss-phase hair to fall out early in some persons. This included both Propecia and minoxidil. OUr products can do it also. The hair was about to fall out and what causes this is new hair stating to grow.
Also, I have read horror stories about stopping minoxidal and then all your hair falls out in a matter of months.
This i also true of all hair-loss treatments, including ours.
Although Propecia. May have the same effect it doesn't seem to be as sever or happen as often.
Likely, this is because propecia does not work as well as minoxidil.
I was wondering if these shampoos have the same effect. In other word is there shedding,
Yes.
and if I stop using it will my hair be in worse shape then when I started.
We cannot guarantee this, becasue your hair may get worse on its own. But early shedding is a sign that treatment is working and is usually associated with a good eventual result.
2) Does either of these products contain Minoxidal?
Proxiphen does , Prox-N and Nano shampoo do not.
3) How often do you have to use these products, and how long do they typically last?
See http://www.drproctor.com tyically prox-N is used 1-2 times a day. A bottle least about 2 months. NANO shampoo 2-4 times a week, a bottle last about 2 months.
Dr Proctor
Thank you for your time and I look forward to hearing from you. Of these 2 products, at this point, I am leaning more towards the Nano shampoo.
Can anyone who has tried Nano answer these questions for me as well? It would be appreciated!!!
