If you have dry hair, you should opt for kinky curly hair products that hydrate and moisturize. People who live in humid areas tend to have frizzy hair and need products with glycerin or sodium lactate. Some people have much kinkier hair in the nape of the neck and need a product designed exactly for kinkier hair textures. Even hard water can affect how your hair interacts with your products. Even more, many products are not pH-balanced, causing your hair’s pH to be thrown off.
