Hey heretogrow, thanks for the support. My aim on this thread was always just to put up my own experiences and try and put up as much research as possible on the important points so people can make an informed decision. I know how important it was to me to read others stories and how much it helped so as we're all in the same boat i just want to try and do the same.
Its been a good couple of weeks for me. I'm just coming up to the end of my 4th months of propecia and no bad things to report and no side effects. Also for the first time i've noticed dozens of little hair sprout at the hairline. They are vellus hairs at the moment so they make no aesthetic difference but i'm hoping that they will thicken up with continued propecia use. Fingers crossed!
Also even though i never had a problem with my crown or top of head, i think it has thickened up a bit. I can't say this for sure and i haven't cut my hair in two months so it could just be that but it appears thicker. I will be posting pictures at the six month to compare to the pictures that i posted at the three month mark so that will be the time to see if there has been any cosmetic change, but again, fingers crossed.
Right now onto the science bit. I know this has been discussed by others but i wanted to go over it again. In september 2011 the first 10 year study in finasteride was published:

Rather than paraphrase because i think it is important for everyone to read, i will cut and past the salient bits into this post. In my opinion this study is pretty good news for everyone and my only two concerns are the relatively small study size (118 men) and the fact that there is no placebo control group. However there are no conflict of interest or external funding sources and the research took place at the Department of Dermatology and Plastic Surgery, Sapienza Medical School of Rome, Italy (hence, as this paper is translated from italian there are some grammatical errors). So here goes:
"Finasteride 1 mg is indicated for the treatment of men with androgenetic alopecia (Androgenetic Alopecia). However, more than 5 years efficacy and safety has not been previously reported. To assess the efficacy over 10 years in different age groups of men with Androgenetic Alopecia. 118 men, between 20 and 61 years, with Androgenetic Alopecia receiving finasteride (1 mg/day), were enrolled in this uncontrolled study. Efficacy evaluation was assessed with standardized global photographs at baseline, 1, 2, 5 and 10 years. Statistical analysis was made using frequency tables and evaluating the chi-square index with its p-value. Better improvements are observed in patients older than 30 years (42.8% aged between 20 and 30 years did not improve also after 10 years) or with higher Androgenetic Alopecia grades (58.9% for Androgenetic Alopecia grade IV and 45.4% for Androgenetic Alopecia grade V had the first improvement just after 1 year). In 21% of cases, the treatment continuation beyond 5 years provided better results. Side effects were referred by 6% of the patients; nevertheless, some of them went on with treatment because of the great results. In our opinion, the result after the first year can help in predicting the effectiveness of the treatment. Its efficacy was not reduced as time goes on; in fact, a big proportion of subjects unchanged after 1 year, improved later on, maintaining a positive trend.
Study population: One hundred eighteen men, aged between 20 and 61 years, in good physical and mental health, with mild to moderate Androgenetic Alopecia (grade II–V according to the modified Norwood-Hamilton scale) were enrolled. Objective examination, pull test, anamnestic data led to the diagnosis. Exclusion criteria at study entry were significant abnormalities on screening physical examination or laboratory evaluation, prior surgical correction of scalp hair loss, topical minoxidil use within 1 year, use of drugs with androgenic or antiandrogenic properties, use of finasteride or other 5?-reductase inhibitors, or hair loss from causes other than Androgenetic Alopecia. Alterations in hair styling and dyeing of the hair were not allowed during the study. Institutional review board approval was obtained each year prior to entering subjects into each study. All men were provided written consent, and the protocol and consent forms were approved by local review boards. The use of any proprietary sampling contact information (e.g., mailing address) was approved by its owner. All patients were treated with finasteride 1 mg/day. They were evaluated by using a color standardized macrophotograph (Canfield Imaging Systems, Fairfield, NJ) before starting the treatment (baseline), after 1, 2, 5, and 10 years of treatment.
At each follow-up, the photos were examined by the same three experts (two dermatologists experienced in assessment of changes in scalp hair growth and one junior dermatologist). Together, the experts assigned to each subject a value (a score) from ?3 (greatly decreased compared to the baseline) to +3 (greatly increased compared to the baseline); a value of 0 specified an unchanged hair state.
Preliminary analysis: Only five patients of 118 abandoned the study during the years because of adverse reactions. Preliminary analysis considered the frequencies of the enrolled patients over the years and the distribution of their initial Androgenetic Alopecia grade in different age classes (20–30 years old; 31–40; >41). Then, the year of the first improvement was identified and related to age classes and the initial Androgenetic Alopecia grade. A third analysis compared the treatment response after 1 year with each of the remaining follow-ups; in this case, we reduced the scores to only three values: improved (for all the scores greater than 0), unchanged, or worsened (for the scores less than 0). We considered the numbers of patients classified in each of these groups for each follow-up, and in case of a significant relation (revealed by using the chi-square index), we built a transition table filled with the empirical probabilities to have a given result after 1 year and those possible in the i-th follow-up.
Persistence and further improvement analysis: The idea of this analysis was to measure the persistence, or not, of the hair growth after 5 years; we compared in details the scores after 5 years with those at 10 years. We identified three groups of patients: the ones that benefited from the 10 years treatment (those with a score at 10 years greater to the one at 5 years), the unchanged but improved (those with the same score, at 5 and 10 years, greater or equal to 0), and the worsened (the remaining ones). We described their significant characteristics using age and initial Androgenetic Alopecia grade.
In correspondence of each follow-up, the three dermatologists jointly assessed the current macrophotograph with the one taken at the beginning of the treatment, by considering both vertex and frontal regions. After their agreement on the results, they assigned to the patient a numeric values from ?3 (greatly decreased compared with the baseline) to +3 (greatly increased compared to the baseline). In the vertex photographs, finasteride showed significantly great improvement at 10 years. In the frontal region, the improvement was less evident.
Preliminary analysis. One patient abandoned the treatment before the first year (because of adverse reactions); just four more before the 10 years follow-up. In our sample, we observed a strong relationship between the initial Androgenetic Alopecia grade and the age classes; in particular, the grade growth with the age class (the chi-square index is 26.6 and the associated probability is less than 0.05). The year of first improvement is directly related with both the age classes (chi square = 9.16 with a p-value less than 0.05) and the initial Androgenetic Alopecia grade (chi-square = 9.51 with a p-value less 0.05). We observed that the patients older than 30 years had better responses than the younger ones (53.6% of patients with age between 31 and 40 years showed an improvement of hair growth at the first follow-up, 47.4% of those greater than 41 years had an improvement at the same time). Furthermore, there is a great part of young patients, 42.8%, that do not show an improvement also after 10 years.
The dependency between the results obtained after 1 year with those observed in the next years tends to significantly enforce; this allow us to consider that the first year can be important to determine the effectiveness of the therapy. For those patients (114) that had the first and the third follow-up (after 5 years), about the 50% (55 individuals) showed a hair growth after the first year of treatment. For these, the empirical probability to maintain the hair growth was 0.45, whereas the probability to have an improvement at 5 years was 0.53 (that is to say that almost one of two patients with an improvement at the first follow-up will show a better improvement after 5 years). For those 52% with unchanged or worse results at the first year (59 individuals), just the 25% (15) will have an improvement at 5 years
After 10 years, the patients with an improvement at the first year (54 of 113, one less than in respect to the previous analysis because one treatment discontinuation) have an empirical probability of 0.04 to have worse results; otherwise, they tend to maintain the hair growth (with a probability equals to 0.28), or more probably, to improve (with a probability equals to 0.68). For those with unchanged or worse results at the first years (52.2%, given by (48 + 11)/113 = 59/113), only 32.2% (19) will have an improvement at 10 years.
It is important to consider that the majority of the patients with no improvements at the first follow-up could show just an unchanged result (in respect of the baseline) after 10 years.
Persistence and further improvement analysis showed the details on the transition probabilities between the scores at 5 and 10 years follow-up; these were significantly important (chi-square = 338.65 with an associated p-value less than 0.05). On 113 patients, the ones that benefited from the 10 years treatment were 24 (21%), whereas the no change were 74 (65%), and only 15 (14%) were the worsened.
Fifty percent of the patients improved after 10 years of treatment have grade IV initial Androgenetic Alopecia and tends to be significant older than the others (37 years old against 33 of the other patients); the unchanged but improved and the worsened are not age-related and have low grades of initial Androgenetic Alopecia.
Adverse reactions: Side effects were observed on 5.9% (7) patients. Libido and ejaculated semen reduction plus erection problems were reported only by one patient, which interrupted the treatment just at the beginning of the treatment.
The most frequent side effect was the libido reduction (5.1%) of the ejaculated semen amount.
Gynecomastia and depression were not reported at all. None of our patients had change in the spermatogenesis process, but it is important to point out that in patients with other problems contributing to infertility (varicocele), the negative influence of finasteride, noted by others, might be amplified.
Androgenetic Alopecia in young males is a psychosociological problem and the number of affected people is increasing. To date, this study represents the longest (over 10 years) reported uncontrolled study in men with MPHL. Our results underlined that finasteride 1 mg/day administration produced significant and durable increases in hair growth in men with Androgenetic Alopecia. Presumably, under the influence of finasteride, whose blood concentration is not going to be reduced over time, previously miniaturized scalp hairs continued to become longer, thicker, and more cosmetically significant during 10 years treatment because it is still working as a selective type, the II 5?-reductase inhibitor. Since miniaturization of scalp hairs in Androgenetic Alopecia develops over a period of many years, it is not surprising that reversal of this process may also take a number of years.
Comparing different age groups, our study underlined that subjects older than 30 years showed a better hair growth in the long term. These findings are in agreement with that of a previous study in men with early-onset Androgenetic Alopecia.
Our results showed also that in contrast with what usually observed with other medications, finasteride efficacy is not going to be reduced over time, especially in the older group since it is well known what happen to androgens in that age in men subjects.
It is interesting to point out that of the 113 patients followed for 10 years, only 14% worsened, whereas the remaining (86%) had benefits (21%) from the treatment duration or (65%) persisted in their improvements. Patients not improved at all after one year (i.e., with a significant decreasing in their hair growth) could be considered not respondent to a long-term therapy.
Side effects were observed on 5.9% (7) patients, but these effects were not age related. Some of the patients who experienced side effects did not drop out of the treatment because of perceived good results. As in a previous study, finasteride 1 mg was generally well tolerated and long-term treatment led to sustained improvement in treated men.
In conclusion, finasteride is a safe and effective treatment for controlling male pattern baldness with long-term daily use even in men over the age of 40 years. The satisfactory clinical results, the few side effects observed, and the lack of alternative medications, led us to consider finasteride an effective treatment especially if taken in the early stages of Androgenetic Alopecia."
