Can you put one hair Colour over another?
Hair dyes pretty much work in the same way. You cannot just easily color over a previous color without having problems occur. However, it’s much easier to color from a lighter color to a darker one. Say if you have light brown hair and you want to go to a dark brown.
How do you keep hair dye from bleeding on each other?
Use conditioner to keep color dyes from bleeding onto lighter hair. During the dyeing process, coat lighter hair in conditioner to protect it. The conditioner will act as a shield when you rinse the dye itself out, lessening the unwanted contact that the dye has with your hair.
Why is my hair unevenly dyed?
Several reasons may cause your hair to take up colour unevenly. You may have applied the colouring agent improperly, residual pigments in your hair may skew the resulting hair colour, traces of styling products were still in your hair or your hair structure is uneven.
How can I hide my uneven hair color?
If the base colour was uneven, you know this is what that made your new hair colour come out patchy or uneven. To avoid this problem, all you need is to again dye your strands, but this time use a new dye with one shade darker than the shade you used before.
Will I damage my hair if I dye it twice?
Yes, you can dye your hair twice in one day with semi-permanent hair dye. It still might damage your hair slightly, but not as much as with the permanent hair dye. We recommend that you would just try in a small piece of hair first before you recolor all your hair twice in one day.
How long do you need to wait to recolor your hair?
How long should you wait before re-coloring your hair? It’s generally suggested to wait at least four weeks between coloring hair. That’s the minimum interval if you care about your hair but it would actually be better to wait somewhere around six or seven weeks if you’re really scared of doing any damage.
Why are my roots lighter after dying?
Similar to the orangey issue, above, when your regrowth ends up a shade lighter than the rest of your hair, it is typically because virgin hair reacts differently to dye than previously-colored strands. The latter is more porous than regrowth and thus quicker to absorb color molecules.
