Stabilizes and maintains the pH balance established by the Thermal Scalp Mask. Neutralizes and lifts away residues on the scalp. For maximum effect, follow Sisterlocks shampooing procedures which are not friction-based, but rather pressure-based. The gliding pressure of our shampooing technique is soothing to the nerve endings of the scalp, which is very important in the compromised areas. Leave on the scalp for 1 – 3 minutes before rinsing. Re-apply if additional cleaning is needed. Relieves itching and sore or sour scalp. Store in a cool, dry place.(4oz.)
