Ammonia is a chemical compound that is commonly used in hair dyes and other hair products. It is a strong alkali that can cause irritation and damage to the hair and scalp. Ammonia can also make hair more porous, which can lead to dryness and breakage.
There are a number of potential benefits to using ammonia-free hair products. Ammonia-free products are less likely to cause irritation and damage to the hair and scalp. They can also help to keep hair healthier and more vibrant. Additionally, ammonia-free products are often more environmentally friendly than ammonia-based products.
