"The majority of men lose their hair not through stress, or bad diet, or lack of sleep, but through the genetic trait of male pattern baldness which is hard to treat through shampoos or supplements alone. Women lose their hair for very different reasons, but the argument still stands that a lot of the hair loss products on the market are just offering false hope. That said, there are a few that really work."
decrease in your blood Prostate Specific Antigen (PSA) levels. Finasteride can affect a blood test called PSA (Prostate-Specific Antigen) for the screening of prostate cancer. If you have a PSA test done you should tell your healthcare provider that you are taking Finasteride because Finasteride decreases PSA levels. Changes in PSA levels will need to be evaluated by your healthcare provider. Any increase in follow-up PSA levels from their lowest point may signal the presence of prostate cancer and should be evaluated, even if the test results are still within the normal range for men not taking Finasteride. You should also tell your healthcare provider if you have not been taking Finasteride as prescribed because this may affect the PSA test results. For more information, talk to your healthcare provider.
Results can take awhile to become apparent, so it’s important to be patient and follow the regimen exactly. It is best to begin using these products at the first signs of balding or hair thinning for the best results. Drinking more water, eating a balanced diet, taking a daily multivitamin, and taking advantage of additional supplements like Biotin can also help speed up hair regrowth.
The best option for many patients with significant hair loss is hair transplantation. Not your father’s “hair plugs” anymore, advances in artistry and minimally-invasive surgical techniques can comfortably undetectably restore hairlines and coverage. Hair transplants are used to permanently restore living and growing hair to an area of the scalp that is depleted of hair follicles.
In either sex, hair loss from androgenetic alopecia occurs because of a genetically determined shortening of anagen, a hair's growing phase, and a lengthening of the time between the shedding of a hair and the start of a new anagen phase. (See "Life cycle of a hair.") That means it takes longer for hair to start growing back after it is shed in the course of the normal growth cycle. The hair follicle itself also changes, shrinking and producing a shorter, thinner hair shaft — a process called "follicular miniaturization." As a result, thicker, pigmented, longer-lived "terminal" hairs are replaced by shorter, thinner, non-pigmented hairs called "vellus."
