Single item ingredients:
Household items such as baby powder, cornstarch, corn meal and white or wheat flour are used for dry shampoo when in a tight pinch.
Combinations of ingredients:
Baby powder and cornstarch is found in a baby bottle form, or you can mix the two ingredients together in a container. Use equal parts. Mix the two ingredients. Another combination is oatmeal and baking soda in equal parts such as 1/2 a cup of each; depending on how much you want on hand. White/wheat flour with ground almonds also makes another combination of dry shampoo by using a 2:1 tablespoon ratio of flour to nuts. Use cornstarch and cornmeal in a 1:1 ratio of ingredients.
Although these light color powders are perfect for blonde hair it may "cloud" brunette shades. If you find this problematic, add unsweetened cocoa powder to your mixture and this should hold you over until you get a moment to shower.
Use your fingers or a brush
Place the ingredient(s) in a small container and begin by separating a segment of hair. Dip one of your fingertips, or a blush brush, into the powder and dab it on to the roots of your hair and scalp. Repeat this process with new segments to cover all the roots. After, massage and shake the dry shampoo into the hair. If your hair still looks oily repeat the process. Once the dry shampoo is applied and hair looks "cleaner" brush your hair thoroughly to remove the excess. You may want to wash your brush after because of leftover residue.
Use the finger technique for or multi-ingredient dry shampoo with a heavier consistency. For recipes calling for heavier granules such as ground oatmeal or cornmeal separate the hair and sprinkle your hair at the roots. Continue to follow this procedure until all the roots are covered. If there is still dry shampoo in your hair flip your hair over and brush it to pull out any excess.
*** TIP: Blow dry hair first if it's damp. Yes, it's gross, but it keeps the dry shampoo from being gummy.
Dry shampoo storage.
As with any of these dry shampoos what ever is left should be placed in a dry, clean container with a tight lid since moisture ruins its consistency.
Make it portable and multifunctional
These recipes are easily portable, and can be used for multiple uses. Place dry shampoos in a small container and throw it in your gym bag or purse. Be sure the lid is on tightly, or if you're still concerned, run tape across the top so it doesn't spill in your bag. Baby power or cornstarch can also be used for a body talc to reduce moisture if needed.
