Thank you for this very comprehensive post It is a lot to research I use Sulfate-Free Loreal Shampoo. i don't use conditioner, but instead use cold-pressed coconut oil on my hair after I wash I'm afraid of applying oil to scalp before wash. I heard that pollutants from environment get in your scalp and if you massage with any type of oil it will cause hair loss. Is this true? I hope not because I would rather like to apply to my hair BEFORE wash and AFTER wash. Your post is very thorough and detailed and I will incorporate as many points as possible. Thank you so much!
