Hi there,
I am sorry your boy has this trouble. It sounds like simple Miliary Dermatitis which is an allergic reaction.
Apply plain neosporin to the scabs three times a day.
Give him one quarter of a chlor-trimeton every 12 hours. It is sold OTC in drug stores:

Do not feed dry food.. canned only:

Fortunately cats do not get as many skin conditions as dogs so they are much easier to diagnose and treat. They can be allergic reactions, fungus or infection.
Here is the most common with photos:

Ringworm can be recurrent and is treated with a topical fungicide or a vaccine shot.
miliary dermatitis can come from a food allergy or the bite of even ONE flea.This is treated with one cortesone shot or neosporen it is safe it he licks a bit.
Granuloma is also usually allergic in nature and can be treated cortesone or antibiotics or both.
There is also alopecia which is usually symmetrical and can be self inflicted:

A staph infection is also a possibility and can recur at times when the immune system is weakened temporarily.
Please look at the photos and let me know which best relates to your cats issues and I will be happy to discuss this further with you.
