How to Colour Hair?

Do you know how to colour hair? The primary rule is, avoid overlapping of colour by retouching surfaces every four weeks. No more and no less. Exactly every four weeks.

If dying or bleaching is scheduled sooner, you overprice the previously treated hair and this is very noticeable from the hair’s dry and brittle appearance.

If you colour or bleach five or six weeks later, you underlap the previously treated hair and create an uneven structure of the hair.

This is harmful since the original chemical process of dyeing or bleaching alters the structure of the hair, to begin with. So an exact four-week retouch is a must.

In addition, after colouring, you must allow your hair to remain dry for three days and three nights to allow the process to oxide properly.
