It was easy to use yes. But it didn't hardly give any color. The color I had was very spotty! It took using over half of the bottle to even start to notice anything.

Usually i have good experiences with the LG bluetooth headset but this one that I received didn't work properly. Maybe old stock, refurbished, return, I'm not sure but I didn't like it and sent it back

Ex Input:
It doesn't work. Don't buy from this seller. I can't return it. It was a gift to my husbamd who is always out of town. By the time he got to it, it was passed the return date and I cannot contact Amazon about this item since they've changed the layout. It was an expensive mistake. Don't buy.
