How long will my husband be in the SHU for contraband?

Hair dye is a minor infraction especially in a camp, but contraband is a loosely used term in the incident reports. Contraband can be a weapon, drugs, obvious signs of operating a business, gambling records or ANYTHING not on the comissary list. Hair dye seems almost like a nuisance charge, we wonder whose bad-side did your husband get on. Our guess is that the SHU stay will be no more than two weeks and he might have some limitations on commissary purchases or phone time but nothing worse (we hope).
