So far, studies allowed us to collect information on alterations of microbiome related to different diseases of the scalp such as Androgenic alopecia, Alopecia areata and Lichen planopilaris.
These results are the first scientific evidences of alterations in microbiome ever observed in such pathologies.
We observed that subjects suffering from Androgenic alopecia present a higher quantity of Propionibacterium acnes when compared to healthy persons. Furthermore, they show a higher % of Staphylococcus aureus and lower % of Staphylococcus epidermidis.
In patients with Alopecia Areata Propionibacterium acnes is also higher. In these cases the ratio between the populations of Staphylococcus epidermidis and Staphylococcus aureus switches towards Staphylococcus aureus, reverting the healthy condition (eubiosis).
In patients with Lichen Planopilaris, a form of scarring hair loss or cicatricial alopecia affecting the scalp, the ration between Staphylococcus epidermidis and Staphylococcus aureus remains the same, while Propionibacterium acnes increases.
