customize your bust your brass routine!

if you are a natural (non-color treated) blonde:

  • in the summer months (when hair is more likely to become brassy), use the bust your brass shampoo + conditioner every other wash.
  • use the bust your brass repair mask 1x per week in place of conditioner.

if you are a platinum blonde:

  • to maintain tone, use bust your brass shampoo + conditioner every other wash.
  • we suggest alternating bust your brass shampoo + conditioner with the kure shampoo + conditioner and multi-task repair treatment.
  • use bust your brass repair mask 1x per week in place of conditioner.
  • if you notice pesky brassiness pop up, use the bust your brass system every wash until desired tone is reached.
  • keep track of your tone: if you're loving your tone, keep up your routine as is. if you notice brassiness peeking in, increase use the bust your brass mask an additional time per week. if you are a little too cool-toned and nearing a violet tone, cut back on the bust your brass routine for a week or two.

if you have highlights, a balayage, or natural-looking (color-treated) blonde hair:

  • use bust your brass shampoo + conditioner every other wash.
  • assess hair's tone and pivot (increase or decrease usage) as needed.
  • those with naturally dark hair should use the bust your brass intense repair mask 1x per week in place of conditioner.
  • please note: naturally darker or brunette hair will fight to return to natural hair color; in this case, increase the usage of system.

if you have gray hair:

  • use bust your brass shampoo + mask every wash or alternate every other wash with the kure collection.

if you are a textured blonde:

  • follow the regimen suggested above based on type of blonde, but use the bust your brass repair mask in place of conditioner for an extra dose of moisture. the bust your brass repair mask is the perfect mix of toning, moisture, and repair which is just what a textured blonde needs.

FAQ

what are bonds?

hair is made up of different kinds of bonds that impact the strength and elasticity of our hair. these bonds are damaged daily by heat styling, environmental stressors, chemical treatments, and more. damage leads to hair looking dull, damaged, frizzy, and unmanageable.

what is bond cure technology?

the bond cure technology used in the bust your brass collection is a proprietary blend of ingredients that are meant to target hydrogen bonds, the most abundant bonds in your hair which are most prone to breakage.

what is brassiness?

brassiness refers to unwanted warm and yellow tones that appear over time in blonde, silver, and grey hair as it is washed and exposed to environmental stressors. the bust your brass collection counteracts brassiness by using ultra violet pigments to neutralize warm tones, resulting in cool shades of blonde, silver, and gray.

what types of damage does the bond cure technology repair?

the bust your brass collection, formulated with bond cure technology, targets all types of damage-- from chemical, to mechanical, to natural breakage and environmental stressors. it repairs the most abundant bonds in the hair, leaving damaged hair stronger after use.

how does the bond cure technology work compared to other bonding products on the market?

the bond cure technology in the bust your brass collection is formulated to target hydrogen bonds, the most abundant bonds in your hair. hydrogen bonds are the most fragile bonds in hair, and are damaged daily by heat styling, environmental stressors, manipulation, chemical treatments, and more. the bust your brass collection targets all kinds of damage and strengthens hair to prevent future breakage. other bond building products on the market target less common types of hair bonds that may not require as much repair from different kinds of damage.

is there any keratin in these products?

no! we’ve replaced keratin with hydrolyzed quinoa, a vegan protein, so the new bust your brass collection is 100% vegan and does not build up on hair when used as directed.
