There is a hair care school of thought that believes that silicones prevent moisture penetration into the hair (and therefore prevents hair from being healthy). Does anyone know if there is any evidence to support (or refute) this?
My background is in Pharmacy but I am here as a hobbyist. I am experimenting with making hair and skincare products (mainly conditioner) for my family and myself. I am thankful to have found a resource such as this.
