Gray hair cover shampoo

These are gray hair cover shampoo and conditioner from LG Household & Health Care.

My husband has gray hair like his mother, but he doesn't dye it.

Washing and rinsing is the same as with shampoo.

It seems like it might be providing some coverage, but there isn't a dramatic effect yet, so I think I need to use it consistently for at least a month.

I'm showing you that a product like this exists.
