Finasteride can cause gynecomastia, which may be reversible by stopping the drug and using selective estrogen receptor modulators (SERMs) like tamoxifen. Lifestyle changes such as weight loss and avoiding alcohol can also help, but surgery may be needed if the condition persists.
A dermatologist refused to prescribe finasteride due to concerns about recent research linking it to male breast cancer, suggesting a topical alternative with minoxidil instead. The user is advised to seek a second opinion, as the evidence for such risks is inconclusive and the dermatologist's reasoning seems questionable.
Using estrogen for hair regrowth is considered ineffective and risky, with potential side effects like breast growth and hormonal changes. Alternatives like finasteride, dutasteride, and minoxidil are suggested, but estrogen is not recommended unless transitioning.
The user, Salt_Ad6339, shares their positive experience with hair regrowth after using minoxidil and finasteride for a year, along with microneedling. However, they also mention experiencing chest/nipple pain and suspect it may be a side effect of finasteride. They decide to stop using it for now and see if minoxidil alone can maintain their hair. Other users in the conversation discuss the potential side effects of finasteride and suggest using an aromatase inhibitor to counteract them.
Topical finasteride (P-3074) can inhibit scalp DHT by up to 70%, with some users experiencing systemic absorption similar to oral use. Users discuss varying application frequencies and concentrations, with some noticing side effects when overused.
