1, diagnosis of hair itself
Hair shows different conditions such as damaged hair quality, permed hair quality, dyed hair quality and healthy hair quality, so the same dyeing method will show different dyeing effects for different hair qualities. Therefore, the stylist will decide the order of dyeing hair according to the different conditions of hair: dyeing the ends first, dyeing the stems first, or dyeing the roots only.
2, the influence of white hair
If there is more than 30% white hair, then household dyes (except black dyeing) will not have satisfactory hiding power. When the white hair exceeds 50%, the household hair dye will fail. It's best to ask a professional colorist to apply proper primary colors according to the amount of white hair. Then, the basic color+target color+appropriate concentration of hydrogen peroxide can show very satisfactory results.

Professional hair dyeing will choose the appropriate concentration of hydrogen peroxide dye according to the target color and the hue span of the hair itself. If the span between the target color and the natural color of hair exceeds 4 degrees, it is necessary to bleach the natural color with bleaching powder before dyeing. In this case, the hair stylist suggests that you choose professional hair dyeing, which is easy to master and control the effect.
