Blonde hair dye does not damage your hair, but if you need to bleach your hair before application, it may be slightly detrimental to your hair’s health. Smart Beauty Smart Color + Plex aims to minimize damage and nourish and repair your hair during the dying process.
It is also advisable to use the bleach-it kit for safe bleaching if required. If you use a substandard bleaching product, your hair condition can suffer immensely.
You should also be aware of Paraphenylenediamine (PPD) in permanent hair dyes. Some people are allergic to it, which can cause a reaction. Henna also includes PPD, so the best alternative to use if you are allergic to it is to opt for Smart Beauty temporary hair dyes, void of PPD.
To find out whether you are allergic to PPD, apply some of the hair dye to your skin for 48 hours. This is called a patch test. If your skin becomes irritable, inflamed, or red, you should refrain from using products that contain PPD.
