All hair types and colors.
Safe, non-harsh, non-stripping spray is especially effective on pale shades of blonde, grey, ash, white and all lighter hair shades that are prone to show stains and discoloration from metals and minerals.
Suggested use is every 3-4 shampoos to keep your color looking fresh and bright.
But, with frequent exposure to well water or chlorine, you can use it more often (even daily) because, unlike chelating products, DREAM FILTER is extremely gentle.
