It is not safe to colour your child’s hair until a child is done with puberty
and has entered their teens, as children are more sensitive to toxic exposure.
Beyond allergy or other skin reactions, a child’s hair and scalp are sensitive
to ammonia and other harsh chemicals found in hair colours. It is only after
puberty; their hair begins to mature and become the hair they will generally
have into adulthood.
Convincing your child for the first haircut can be difficult. Nevertheless, you can make this easier.
