The Ultimate List of Must-Have Products For Blondes

John Frieda's Sheer Blonde is the OG line of blond products, so I trust pretty much anything the brand offers. The lightening shampoo ($10) is ideal for all blonds, and you could easily use this product daily for the ultimate lightening look. However, I suggest using it as a maintenance product once a week.

Obviously, this is not recommended for brunettes with blond highlights, unless you want your brown locks to start turning orange.
