I permed my son’s peyos. The result, a great curl.
Bad part, baiscally a perm is the stylist puts rollers in ur hair and then chemicals above it. The hair just above the roller (cuz she cant get the roller onto the scalp) gets frizzy and not part of the perm.
Also I found it oxidized my sons hair a little.
One more point, right after the perm, like for the first two weeks, the curls were boing boing until the perm settled a bit.
