1 tablespoon Arm & Hammer Baking Soda
1 cup water
Mix together in large plastic bottle (can be shaken to mix). If the bottle has a narrow opening, the use of a funnel will make it easier.
Store in 3 oz. plastic fliptop bottles (can be found at Walmart, CVS Pharmacy, etc. in the travel section).
Make as much as you like at once and store in a bigger bottle.
Soak hair in shower.
Squirt one (1) 3 oz. bottle onto your head (men may not need as much).
Massage into your scalp.
Repeat if desired, but once should be all you need.
Dry/style as usual.
