4. Which is better: hair colour without ammonia or with it?

Hair colour without ammonia is generally considered better for several reasons.

Additionally, hair colours without ammonia tend to have less unpleasant odours, making the colouring process more pleasant.

5. Are permanent hair colours safe to use?

Permanent hair colours are generally considered safe when used as per the instructions provided. However, it is important to keep in mind that most hair colouring products contain chemicals that can cause potential allergic reactions or scalp irritation in some individuals. It is recommended to perform a patch test before applying any hair colour and to follow the manufacturer's guidelines carefully.
