my mom always buys this, she has dark brown hair and this is her favorite product to use. good price and good quality, the odor is not too strong compared to american brands.

This covered my gray hairs and didn't have that horrible smell most western product have. I noticed coror fades a little after a few months but this is more gentle on my scalp and hair.

My hair color is dark brown and I bought this item in the shade 4F. I tried it on both bleached and white hairs. For bleached hairs, this product dyed my hair to dark brown, almost black. It is much darker than the shade on the chart in the item description.

For white hairs (which is what this item is intended for), I left it for much longer than my bleached hair and it only dyed my hairs into a very light brown. My dyed white hair is similar to shade 1 on the chart. I wonder if ordering a darker shade will work for a covering my white hairs.

Pro: no strong smell, does not damage hair
Con: hard to expect what color will turn out

Gave it to a friend, and she said it didn't really do much for her hair
