Can I dye my hair on cloudy days?

You can dye your hair on cloudy days, but it will slow down when it is cold. Barbers usually use heat to speed up coloring.

Perm is a kind of hairdressing method, which can be divided into physical perm and chemical perm, of which chemical perm is the most commonly used one. Perm can make your hair richer (curly). Change the shape and direction of hair (curling is not very effective).
