Reply To: Paper thin fingernails
Testosterone is known to promote nail and hair growth. If Testosterone levels are low, nail vitality could be too. A simple blood test can determine if this hormone is in a normal range or not.
I’m using Androgel every 2-3 days and it has actually improved my brittle nails (which I believe I got from taking Prednisone) but my nails were never as troublesome as what you describe.
Using a prescription Testosterone cream could have side affects that might outweigh the benefits, especially if you may be prone to heart conditions. Please consult with your doctor and thoroughly weigh the pros and cons of Testosterone replacement therapy before deciding to try it.
