I switched to using homemade “shampoo” from baking soda around a year ago. I have beyond-waist-length hair, so this was no small endeavor. It took me a while (maybe a month?) to get the recipe perfected to the right ratio, but once I did, it was awesome.
Homemade Shampoo using Baking Soda
1-2 tsp baking soda in 16 oz water
Squirt over hair, massaging or combing in with fingers.
Rinse well. Follow with Apple Cider Vinegar rinse.
I currently use ketchup and mustard bottles (courtesy of the local dollar store) for our shampoo and conditioner. Red is for shampoo (because it comes first… I had to have some way to remember easily or I would forget!)
I put 1 teaspoon of baking soda in the bottle using a funnel and fill it the rest of the way up with water. Then I put on the lid and give it a shake or two, and its good to go!
