A chemically based permanent waving product that has a pH from 7.5 to 9.5. Stronger than acid perms, alkaline perms are designed to produce tight, firm, springy curls rather than the looser curls produced by acid perms.
Always detangle wet hair with a good quality hair pick or wide toothed comb. Make sure that the pick or comb's "teeth" are smooth to prevent snagging or ripping delicate wet hair.
