Deca: Hmmmmm
What can be said about this
steroid. There is so much misconception that deca is the safest
steroid, both on the hair and on the body. Let the myths lie. Although deca does not convert to DHT it does converts to DHN. DHN is less androgenic than deca. The more androgenic the more likely to cause hairloss but this is somewhat a generalisation as androgenic activity is not the only influence of hair loss. Proscar and deca do not mix well. The reason for this was touched upon above "For this reason finastride will work when used with
steroids that convert to dht via the 5AR enzyme." Now if the conversion of nandrolone to DHN is prevented then there is more active nandrolone (which is by far more androgenic than nandrolone. If you are noticing hairloss when on deca it is best to discontinue use.
Spironolactone or flutamide (applied topically) are effective in treating and limiting some damage on the hairline. They are both said to compete with the
steroid used for androgen receptors located in the scalp.
