Ammonia raises the pH of hair to about 11.5. At that extreme level, the integrity of the outer layer (the cuticle) of the hair is opened such that it never closes again. Depending on hair density, it can basically ruin your hair.

How do ammonia absorption refrigerators work to cool food and beverages efficiently?

Ammonia absorption refrigerators work by using a combination of ammonia, water, and hydrogen gas to create a cooling effect. The process starts with ammonia evaporating in one part of the system, absorbing heat and cooling the surrounding area. The ammonia gas then travels to another part of the system where it is absorbed by water, releasing the heat and returning to a liquid state. This cycle continues, with the ammonia gas being absorbed and released, creating a continuous cooling effect that efficiently cools food and beverages.

Is hair dye bad for your hair?

There are few different types of "no ammonia" hair colors in the market. Some hair colors have ammonia substituted by mono-ethanolamine which opens the hair. Ground rule is blonder the color, the more ammonia or mono-ethanolamine is needed to open your hair and lift the color. Ammonia is not allergen, it is the strong odor of it that makes people take a step back. How ever there are increasing number of allergic reactions to mono-ethanolamine. There exists also hair colors that do not contain ammonia or mono-ethanolamines, but in general those colors are limited in range and can not lift enough when you want to be blonde :) So it's a trade off. . I use an ammonia free hair colour and I am very blonde and I know you can be blonde with about 3 different hair ammonia free hair colour ranges!!
