How often you polish your nails in a week and which nail polish brands do you prefer to use?

I don't paint my nails every week, but just once in a while, as its important to allow your nails to breathe and moisturize them often in order for them to look good. I also would not recommend anyone to wear nail polish every week continuously, instead keep a gap where you don't wear any color at all.
I dont have any particular brand as I am not fussy on that, but as long as th brand is good and I like the color.

My favorite brand is revlon. This brand lasts for long time. Usually i will change nail polish once in a week. Occasionally i will change for functions which i am going to attend.

i try to have it cleaned and polished once a week, or at least once every 2 weeks. i love sally hansen nail polishes and nail care products because my nails tend to be weak and breaks easily.

Normally weekly once i will polish my nails. Very rarely when i go for function i will polish my nails with matching dress color.

I go to the salon for my pedicure but rarely do I ask the manicurist to apply nail polish on my nails. Those rare occasion when I go for a full pedicure, I usually settle for a neutral color of tan. Since I only let it stay on my nails for a couple of days I am not choosy when it comes to brand. I use whatever is available.

I think another reason can be the weather.Beacuse my hands are more dry in the winter

I don't wear nail polish at all. I used to wear them before but my nails would get that yellow tinge after taking them off so after that I decided not to put on nail polish.
