Fungus occured post 20 days of 2000 drafts FUE Surgery, will this effect the regrowth? (photos)

Fungal infection after surgery may be a sign of immune compromise since fungal infections are almost not heard of.Contact your doctor.

that is not fungus at all ! that is just unproper washing of head . you do not wash with massage and enough pressure and skin has become dirty ..Dont forget that you may wash your head with normal pressure and if you need you can use a wet towel with soap for massage the scabby area, it Works very well to remove scabs .Patient may feel free to loosen any scabs on his/her head by massaging and that will not  damage the grafts after 2 weeks . 

A fungal infection immediately after the hair transplant that is well and timely treated should be ok with regard to hair growth. You will know in 6 months for sure
