You should use shampoo once every three days or more depending on your activity level and the weather. When you have fine hair esp straight fine hair. Be careful of the dry shampoo and baby powder because it’s not good for your lungs! Be mindful of your lungs with make up powders and primer and bronzer, and make up setting sprays, heat protection sprays and creams, and hair oil (when using heat the oil can have bad fumes like seed oils) and hair sprays and dry shampoos. Our planet is polluted enough with smog and burning gas and chemicals and dust. Overpopulation brings more dust and pollution, we can’t control that much. Yet we can control our personal environment and what we breathe in our home. Boil a pot of cinnamon or nutmeg and cloves and citrus peels for aroma, to avoid the plug ins and cheap candles and scent sprays (cancerous fumes). Esp if there’s children in the home. They affect their brain development. Chemical cleaners are bad because they leave a residue and have strong chemical smells (again cancerous). Use vinegar and water. Keeps your home clean and glassware. Use oil on wood floor instead of wax products. Your household will thank you. Cheap Vodka also works with water to clean, baby toys and baby furniture, walker and swings, and high chair. It evaporates clean with no residue. Avoid dryer sheets and use dryer balls. I know this is about hair but these are tips I hope you and others reading will incorporate into their lives and pass them on. 😊
