If yes ,are there are salons for infants?

No. Dandruff comes from the skin of the scalp, not the hair. Have the excessive dandruff diagnosed by a dermatologist for treatment.

It's not dandruff most likely it's cradle cap. There are shampoos and such to help with that, but for the most part you are supposed to leave it alone until it clears up on its own.

No, because its not his hair. its on his scalp called cradle cap. Get a soft brush and brush it off. You can try baby oil, too.

Very much doubt it! Hair doesn't cause dandruff, scalp dryness does. Maybe mix a little selsun blue with his baby shampoo?

when my niece was 3 months old, she had ALOT of dandruff. Like big pieces. Her mom combed them out and washed her hair everyday with baby shampoo

Its not dandruff, its cradle cap and know shaving there head won't take care of it. Try baby oil and comb it out.

No, it won't help. Both my babies were/are bald and had very bad dandruff. Babies have dry skin and it takes a while for it to regulate itself. Make sure it isn't cradle cap and if it isn't then the best thing you can do it let baby grow out of it. By age one my son didn't have it any more. He only now got it back at age two because he insists on rinsing his own hair and leaves some shampoo in his hair.

Are you sure he doesn't have cradle cap? I don't think shaving his hair will do anything for it. I would not shave his head if I was you. Just make sure to rinse really good after washing his hair. Both of my kids had this problem and I just switched to Johnson+Johnson baby shampoo and it went away(yellow shampoo) I would ask your peditrician during the next visit.
