No matter what is the condition of the hair what gives the hair ability to be manageable and healthy is pH.
Your hair has a natural acidic pH level, and hair needs acidic pH to thrive.
The pH scale goes from 0 to 14 and substances with a pH level of 7 are considered neutral. Human hair is healthier at a pH level of 4 to 5.5, which is slightly acidic. Water has a pH level of 7, so is too alkaline for human hair. When human hair comes with contact with alkaline substances, the cuticles the hair becomes open and rise up, making the hair very porous, and will be more prone to breakage.
