Understanding pH and Hair Care

In this video, Jen from the Chroma Crowns YouTube channel explains the pH scale and its relevance to hair care. The pH scale ranges from 1 to 14, with water being neutral at 7. Substances below 7 are acidic, while those above are alkaline. Hair's natural pH is slightly acidic, between 4.5 and 5.5, and maintaining this range is crucial for healthy hair. Jen discusses how chemical processes like coloring and retexturizing affect hair's pH and the importance of neutralizing these effects. A demonstration using baking soda and vinegar illustrates the neutralization process. Jen also shares tips on using apple cider vinegar as a natural hair rinse to maintain pH balance.
