Itching is the key symptom that affects people with Lichen Planus. The appearance of the rash can be distressing for some, especially if it occurs in intimate areas such as the genitalia. Furthermore, as the skin lesions heal, darkly pigmented blemishes may appear in their place which can take months or even years to resolve, particularly in those with a darker skin tone. If Lichen Planus occurs on the scalp it can lead to patchy hair loss which may be permanent. Pitting, ridging or complete detachment of the nails eroded by LP can also look unsightly.
