To find out the condition of the hair follicles, dermoscopic testing is available.
Dermoscopic testing allows observation of the hair and scalp and also allows precise measurement of the observed structures such as the diameter of the hair shaft. Therefore, it is increasingly used for the diagnosis and differential diagnosis of hair and scalp diseases. Hair follicles can be visualized dermoscopically, but only in relation to the mouth of the follicle.
Empty hair follicles or empty follicular orifices seen dermoscopically may be seen in the physiologic intervals of the hair growth cycle, when resting hairs are shed and the next long-term hairs have not yet formed. It can also appear in baldness, androgenetic alopecia and so on.
To know the health of the hair follicle, it is still recommended to go to the hospital in time, under the guidance of the doctor for diagnosis and treatment.
