YouTuber Ellie Thumann collaborated with Hally to create a limited-edition blue hair dye that's ammonia-free and infused with beneficial ingredients like moisturizing aloe and stimulating ginseng. The special Blue Crush Color is
applied in the form of a foaming hair dye that washes out in just four to six weeks, providing a perfect way for Gen Z to refresh their look to match their mood.
The demi-permanent color can be applied at home with ease thanks to a kit from Hally that contains all of the essentials for a DIY coloring job, including foaming developer, hair dye color, a pair of hair clips and latex-free gloves, plus other products to create a spa-like experience at home like soothing undereye gels and de-stressing putty.
