Covering your hair by wearing a hat or scarf will give you some protection, but it may not be enough.  The sun will usually lighten your hair form 1-2 levels in between colorings. Protecting your hair from UV and UVB rays from sun exposure can save your hair from  becoming frizzy, dry, brittle and faded. We suggest that you use a sun protectant such as the Sun Veil, Color Conserve Daily Protect, or the Protect Leave-In Conditioner.

When should you consider letting your hair go gray?
