Your changes will revert for the most part. However if your testicles shrank, there's a chance they will not grow back to their normal size, and your breast tissue is likely permanent. Also if you've had fat deposits in your face due to estrogen, and they are lost, you will probably get a more aged appearance as the elasticity of your skin has been compromised.
If you have had an orchiectomy then you will probably need supplemental testosterone in order for your skin and hair to become more oily.
