the 1940s, but their numbers have decreased as permanent waves are not as popular as they were in the 1980s. The first popular home permanent was the TONI brand, manufactured in Forest Lake, Minnesota. The Toni company used a set of twins to advertise their products; one with a salon perm and one with the home perm. They introduced a number of types and brands over the next four decades (Silkwave, UnCurly, Tonette, Silver Curl, Prom, Scatter Perm, Lightwaves, Epic Waves) and a formula to remove curl: Curl-Free™. The other popular brand was LILT by soap king Procter & Gamble which included a Foam Perm in a can called "Push Button" Lilt and a 'Milk Wave' that used fresh milk as part of the lotion as well as a children's perm. Other types of perms included "No-Lotion" perms that used specially treated "end papers" to produce the wave (PACE, SELF) and 'self neutralizing' perms that needed no neutralizer but had to 'set' by drying the hair on the perm rods after rinsing out the wave solution. 'No-Mix' Liquid Neutralizers were introduced as many perms were 'air' neutralized or used a powder that was mixed with water or a powder / liquid combination. Other brands included Richard Hudnut, Ogilvie, Revlon and Nutri-Tonic. At the peak of the 'Second-Wave' of popularity in the 1970s/1980's a number of new brands and types of perms were introduced including "No-Ammonia" perms and "Soft" perms (Rave) which guaranteed "No-Frizz" results even on bleached or tinted hair as well as "Temporary" perms that lasted only a few weeks before washing away leaving hair in virtually the same condition as before you permed. Other types included customized versions that let you adjust the curl level before you made it 'permanent' and 'spot' perms that let you curl just certain parts of your hair ( bangs, crown, ends) and leave the rest of your hair untouched. Another brand that was a household name in Britain in the late 1960s and 1970s was Twink (home perm).
