Does getting out in the sun really play a role in hair growth and health?

-i have been reading that the sun contains vitamin D, and also that hair grows quicker in summer, is this true?Sun does help your hair grow and keeps it healthy. It also lightens up your hair as i used to have bleach blonde hair and whenever i went out in the sun it lightened it up and took away any yellow tones:)

Hope it helps.yes, vitamin D really helps hair growth, but the sun between 10 and 4 affects it. this only damages your hair and even skin, so avoid it and stay on the early morning sunlight.
