There are many things to be aware of when dyeing gray hair. First of all, the dyeing of gray hair is so dark that if you repeat dyeing it to the tip of the hair, the hair will become rough. If you just grow it, the part that is not dyed is prominent, and it is easy to color frequently.
Therefore, when dyeing, it is recommended to use only the root as much as possible. Secondly, the hairline around the face has a lot of gray hair and is not easily dyed, so it is better to apply it first. At this time, if the dye is attached to the face, it is difficult to remove it, so apply petrolatum etc. around the face so that it does not stick to the hair. I think the choice of the dye should be the one that suits me best. Hair manicure is recommended for those with weak skin and those who do not want to damage because they do not attach to the scalp.
Hair dye is recommended for those who want to dye from the root firmly and choose a color. There is also henna color, but once you do henna color, it will be difficult to perm or normal color, so we do not recommend it unless you are particular about organic. The only thing I can say is that it is definitely better to dye in a beauty salon regularly than to dye it yourself.
