Studies suggest that CVG often occurs in individuals in a secondary form to other ailments. However, the condition can also be present on its own. CVG can be classified into two forms: ‘primary’ (essential and non-essential) and ‘secondary’.The classifications are:

Primary essential
Primary non-essential
SecondaryPrimary essential CVG is where the cause of the condition in unknown. It has no other associated abnormalities. This occurs mainly in men, with a male:female ratio of 5:1 or 6:1, and develops during or soon after puberty. Because of the slow progression of the condition, which usually occurs without symptom, it often passes unnoticed in the early stage.Primary non-essential CVG can be associated with neuropsychiatric disorders including cerebral palsy, epilepsy, seizures, and ophthalmologic abnormalities, most commonly cataracts.Secondary CVG occurs as a consequence of a number of diseases or drugs that produce changes in scalp structure. These include: acromegaly (excessive growth hormone levels due to pituitary gland tumours), and theoretically, the use of growth hormone itself or the use of drugs that mimic the effect of growth hormone (such as GHRP-6 and CJC-1295). It may also arise in association with melanocytic naevi (moles), birthmarks (including connective tissue naevi, fibromas and naevus lipomatosus), and inflammatory processes (e.g. eczema, psoriasis, Darier disease, folliculitis, impetigo, atopic dermatitis, acne). Treatment
Options for medical treatment for this condition have been limited to plastic surgery with excision of the folds by means of scalp reduction/surgical resection. Scalp subcision has also been suggested as a treatment. Additional suggestions also include injections of a dermal filler (e.g.
