I have been blonde for almost 4 years now and tried a lot of purple shampood but this by far is the best product for blonde hair . Works as a charm. Left for 10min and really happy with the results. Tip: comb through ur hair after you put the mask in for an even saturated results.
This product does what it says...it reduces brassiness in blond dyed hair and highlights grey/silver hair. Only use sparingly and don’t leave on for long as leaves tinges of purple, which does wash out.
