Can colouring hair do damage?
It can, but not necessarily. If harsh chemicals are employed, such as peroxides, frequently, then the damage will show itself one day. It is less likely to get hair damage from colouring, using off the shelf D.I.Y. products then in the salon where much stronger chemicals are used for longer lasting result. Some pre-packed hair colours may even be good for hair, coating the shafts and protecting it from the U.V. of the sun and other elements. When using any harsh chemicals it is important to avoid contact with the scalp to prevent irritation, which can result in real damage.
