Millions of dollars have been spent in research and development and then advertising alone between all the competing hair color companies, and naturally they will tell you that their hair color is superior to their competitors.
Some will claim their dye has low ammonia, is organic, safe, will cause less damage to your hair and so on.
The truth of the matter is that most hair dyes that you can purchase online or from a store, and that is manufactured by a big reputable brand, is safe and okay to use.
The risks however are that it depends what condition your hair is to begin with, and then what you are hoping to achieve by coloring your hair in the first place?
As a rule
- Semi-permanent hair colour won’t damage your hair as there is no ammonia, peroxide, or oxidation of your hair pigment molecules. Note that this also means that you can’t lighten your hair.
- Natural colours such as Henna, Coffee basically stain the hair and the color will wash away over time, however beware, these types of hair colors can cause problems with other color or hairdressing treatments.
- Reputable permanent hair colour is fine if you are doing a root touch up, covering grey hair, sticking to hair colors that are close to your natural hair color.
My recommendation is to always seek any hair color advice from a professional hair colorist, particularly for anything where going lighter, or using permanent color is concerned.
