A trichoscope is an instrument used to examine the scalp and hair in detail. It is a specialized microscope that can provide a magnified view of the hair follicles, allowing the trichologist to examine the health of the scalp and hair in greater detail.

A UV light trichoscope is a type of trichoscope that uses ultraviolet light to examine the scalp and hair. The ultraviolet light causes the scalp and hair to light up in different colors, allowing the trichologist to see any problems that would not be visible to the naked eye.

Both types of trichoscopes are useful in assessing hair health as they can provide a magnified view of the hair follicles, allowing the trichologist to examine the health of the scalp and hair in greater detail.

Additionally, the UV light trichoscope can help detect fungi, bacteria, and other microorganisms that may be present on the scalp and that may be responsible for hair and scalp problems.
