All this is right up my alley girls and boys!!I have a business where I make and sell skin and hair care products. I haven't been onhere since April, but have just bought the new TM31, so am all excited about my timmy again! If you're using any soap (or bi-carb) on your hair, make sure you do a vinegar rinse. If you don't like the smell of vinegar, use a solution of citric acid - 1/2 a tsp in a litre of water.Soap and bi-carb are alkaline. Our hair needs acidity to make the cuticle sit down.Saponified oil is oil which has been made into soap using either potassium hydroxide for liquid soap or sodium hydroxide NaoH for solid soap bars. NaOH is simply caustic soda. None of this is left in the finished soap if it's made properly, but the soap will be alkaline.I'll post some recipes for various skin care treatments if you're all nice to me!
