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.
Daily Hair Tip
Whenever possible limit or avoid using a brush on curly tresses. Instead use a widetooth pick or comb with "hair friendly" edges that won't rip or tear fragile curls.
