Keeping it simple

If you’re thinking about coloring your hair or covering grey hair but want something that causes less harm to your hair than permanent hair color. Then you should try hair darkening shampoo, which are specially designed to color your hair without any damage. 

Hair darkening shampoos are good for people who are allergic to permanent hair color. Actually, the hair darkening shampoos have plant-based hair coloring formulas. Like semi-permanent hair color, hair darkening shampoo also starts to fade with hair washes. 

So today, we are here to provide some knowledge about hair darkening and, most importantly, review and recommend some best hair darkening shampoo to cover grey hair. So let’s get started!

What is a Hair Darkening Shampoo, and how does it work?

A hair darkening shampoo is a formula infused with plant pigments to color hair when left for a while on hair. Actually, it works by depositing the plant pigments around the hair shaft and then coat it with a plant color. 

Through this, the plant color remains on the hair. But it starts fading with time when hair is washed. So, hair darkening shampoos are a great choice and better than permanent hair color in terms of hair damage.

But you have to use them, again and again, to keep the color on your hair.
