11. R+Co SUNSET BLVD Daily Blonde Shampoo
BEST PURPLE DAILY SHAMPOO FOR GRAY HAIR

PROS
- Can be used daily without residue
- Hydrating formula
- Leaves hair shiny
CONS
- Expensive
While many purple shampoos are meant to be used once or twice weekly, “this unique product from R+Co can be used daily and will not make the hair have a violet hue,” Dueñas explains. “The pigment in this shampoo is light, allowing for daily application if need be.” It has a top-notch ingredient blend, too: glycerin, sunflower extract and pearl extract nourish hair and add shine.
12. Natura Anti-Brass Blond and Gray Shampoo
BEST STRENGTHENING SHAMPOO FOR GRAY HAIR

PROS
- Fortifies fragile hair
- Counteracts brassiness
Since gray and blonde hair tends to be more fragile, you want to wash with something that can strengthen strands, too. “This shampoo from Natura contains a unique technology called Pro-Teia biotechnology which helps restore the hair from the inside out, specifically focusing on the damaged areas on each strand,” Du explains. The purple-tinted formula “is only meant to be used when you notice brassiness and yellowness coming through, so think of it as a great occasional treatment to alternate with your normal shampoo.”
