Post-perm, avoid washing your hair within the initial 48-72 hours. Steer clear of steamy showers, which might straighten your curl pattern. Also, don't manipulate your hair. Also, when detangling, refrain from using combs or brushes. Instead, opt for gentle finger detangling. When you wash your hair after a perm, use moisturizing products that don't leave a residue. You also want products that help repair and maintain the hair's structure.
