Drape a towel over the shoulders. Hold the spray about 10cm away from the hair and spray enough gel evenly over DRY hair to cover both the scalp and hair completely, ensuring saturation. Avoid spraying into the eyes and face, and do not inhale the spray. Use fingers or a regular comb to distribute the gel thoroughly from roots to tips. Leave the gel on the hair for at least 15 minutes, or longer if needed. Apply shampoo directly to the dry hair, lather well, then rinse with water. Repeat the process, then apply conditioner, rinse, and dry. Hedrin Once Spray Gel includes anti-foaming agents, so the shampoo may not lather easily. If needed, repeat the entire procedure, remembering to apply shampoo directly to dry hair.
