The Antibiotics still working well for you Zorreo? Hope you are doing well.
I've changed my routine a little because the isopropyl alcohol was becoming too damaging to my hair. I have since been using Everclear 95% grain alcohol (190 proof) found in liquor stores. It's so potent that it's illegal to sell in some states but can instead be found online. Grain alcohol is much less drying and safer than using isopropyl alcohol and some studies suggest it's better at killing bacteria.
I mix 12 ounces of the grain alcohol, 10 drops of lemongrass oil, 10 drops of oil of oregano, and 10 drops of rosemary oil. Rosemary I discovered is antibacterial, good for hair follicles, and has dandruff control. I also mix the same ratio of oils in the unscented sulfate free "Sweet Baby" brand baby shampoo. I've been using this combination for a week with amazing results. I no longer have dry scalp or irritation and there is no alcohol smell when mixed with essential oils. My hair feels like it's getting thicker and looks more healthy than ever. It is very soothing after applying with a cotton ball or when using the baby shampoo with the essential oils. Give it a try sometime if you are still having problems with your hair or scalp.
