Method 1: Identify by observing the face shape and color.
Real nail pollen should be light yellow-green in appearance and smell a touch of grass.
However, if chemical red soil or nail pollen is added, it will appear slightly dark red or even black, smell without the fragrance of leaves, and feel rough and dry.
Method 2: Direct hair dyeing method.
Take a handful of hair and nail pollen and see the dyed color. Usually pure nail pollen should be reddish brown, reddish brown or orange, which is relatively simple and difficult to dye black hair itself.
Method 3: smell it.
Nail pollen without added chemical components is the smell of fragrant grass.
If it is identified as a pure plant by the above method, but it is difficult to be colored or not colored at all after use, it is inferior henna or powder that is not henna at all.
Method 4: Look at the status.
The paste is definitely not pure plant, it is added with additives. Only powder can be a pure plant. However, the use of paste is relatively simple.
