Anything that caused stimulation of the right hormones, and/or increased blood supply to the follicles that previously did not grow hair, or had unnoticed vellus hairs could cause a situation where terminal hairs could form.
If one had achieved full permanent removal, however, the picking off of these new hairs would be childs play for an experienced practitioner.
I have clients who come in every 3 to 6 months for appointments where we do more talking than treating while I hunt down 100 or 200 hairs from the entire area we used to need 30 hours just to get a foot hold on. There is a lot of search in these Search And Destroy Missions.
I was going to try to ignore the fact that you are not suggesting Dole Pineapple Juice in your subject line but I just can't ignore it. Evil James has taken over! >;-)
Do yourself a favor, save yourself from an early grave (Lyle Alzado, Rick Rude ring a bell?). If you insist on "juicing" please allow me to take out a term life insurance policy on you. The $40,000 or less I will spend will return me $2,000,000 when you die in your 40's or early 50's
My friend the late Don Lemmon proved that given a proper eating schedule, food separation, and utilizing economy of exercise, one could build a natural body that beats juicers if given the time. Sure Juicers get quick results, and then they have to deal with the losses ... loss of friends due to their roid rages, loss of sexual performance, problems in the renal, liver and kidney systems, and so on.
I highly recommend that you read "Know How Book One" and "Know How Book Two" (there are 4 in the set, but no one who is not planning to be a personal trainer needs to read more than one and two in my opinion.) These are available at www.buylemmon.com
