Joico K-Pak Professional Cuticle Sealer pH Neutralizer Joico K-Pak Professional Cuticle Sealer pH Neutralizer smoothes and tightens the cuticle locks in curls and colour and reduces pH swelling to restore hair back to its natural state of 4.5-5.5. Cuticle is locked down and sealed. Any sign of swelling or raised cuticle is diminished. It deactivates and removes ammonia and peroxide residues while eliminating perm odours.
To use: Apply to clean, towel dried hair and leave on for up to five minutes before rinsing out.
