How To Care Hair After Colouring. To prevent damage after hair colour the best thing to do is keep your hair. This can make your Colour a lot darker.
Brushing it whilst wet raises the chances of breaking of stretching the hair. In contrast cold water tends to seal the cuticle. Because dyed hair is weaker when wet you will need to avoid brushing it.
So when reColouring choose a Colour 2 shades Lighter than your desired Colour outcome.
This will help to maintain the hairs moisture level and will help to smooth the cuticle layer and ease any problems with porosity. Although it may seem inconsequential properly rinsing hair is essential to achieving the desired final color. Have your hair trimmed on a regular basis to prevent split ends from traveling up the shaft of the hair and causing even more damage. Dont use hot water when rinsing or washing your colored hair because it will open up the hair cuticle similarly to the chemicals found in hair dye.
