•Clarifying shampoo to remove debris and styling product from hair. This usually comes with the kit, but if not, just buy a clarifying shampoo at the drug store.
•2–6 oz of Brazilian Keratin Treatment depending on length of hair. I used the about 2.5 ounces of solution. It's always better to have too much than too little. You can always use leftovers for your next treatment.
•A straightening iron that heats up to at least 400 degrees (preferably 450˚F) and is between 1" and 4" wide, depending on your personal preference. I used a 2" wide iron by Babyliss that heated up to 450˚F.
•A mask usually comes with the kit, but if not, just buy an anti-dust mask or surgeon's mask. They can be found at hardware stores near sandpaper/saws. Some fumes are released as you use the straight-iron on your hair, so this prevents you from breathing in too many chemicals.
•A blow-dryer with both medium and high heat settings.
•Plastic gloves to protect your hands during the Keratin application.
•Butterfly clips to hold upper sections of hair in place while you straighten the under-layers.
•Plastic bowl (optional) to pour Keratin treatment into for ease of application.
•A wide-tooth comb to remove knots after shampooing and also to distribute the Keratin Treatment through your hair and remove excess.
•A snug shower cap (for the 3 days when you need to shower, but can't get hair wet).
