Hi, I Have Developed White Patches In My Beard, Just

Hi,

I have developed white patches in my beard, just below the chin, which started about the size of a coin and recently grew slightly. The white hairs are very strong in colour and are localised only to these patches and I would like to know of any possible remedies? I have read of various causes ranging from Alopecia to a fungal infection or even a deficiency in vitamin B.

Your help would be much appreciated.

Many thanks

Chris
