The body has its microbiome – an ecosphere of fungi and bacteria, wherein they exist in a delicate balance (i.e. there are more friendly microbes as compared to the unfriendly ones), and they make sure that the body is healthy and functioning optimally. Making sure that the scalp ecosystem is well balanced is very vital for a healthy scalp and good hair growth. An unhealthy scalp causes weak hair strands, hair thinning, excessive hair shedding, and poor hair growth.
