Here are more interesting facts regarding our body's absorption (or lack thereof) of finasteride...
In 2014, the
Int l Jour of Clinical Pharmacology published findings from their investigation of this specific topic.
1) SERUM FINASTERIDE Levels with
TOPICAL versus
PILL form.
The finasteride levels found in the serum (blood) of patient who used 0.25% topical finasteride once daily were well below the assay s ability to detect and quantify at nearly every point. The spike in serum finasteride levels of patients taking the pill can be seen below.
2) SERUM DHT levels with
TOPICAL versus
PILL form.
Once-a-day use of the 0.25% topical finasteride resulted in much a less severe decrease in DHT plasma levels (19%) that those seen in patients using the pill once a day (70%) or twice daily use of either topical or pill form. Our blend uses a lower percentage of finasteride than that used in this study and our patients only use the blend once (not twice) daily.
3) No significant change in serum testosterone levels detected with either treatment.
4)
A follow-up study showed the topical solution reduces scalp DHT levels by about 70%.
Despite these findings, this alternative to the Propecia pill is not necessarily for everyone. Safety profiles of topical finasteride has not been properly investigated at this stage. Not everyone may have the hair growth that we have seen in many of our patients when using the topical blend.
It is important to highlight the facts as they have been demonstrated.
