Scalp pruritus is a medical term for itchy scalp that occurs due to scalp irritation. The common presenting symptoms include dry and itchy skin, bald patches, scales, flakes, redness, pus-filled sores, and mild swelling. Having an itchy scalp leads to hair loss often because of the underlying condition.
Itchy Scalp And Hair Loss
Itchy scalp and hair fall often occur together. An itchy scalp can be a symptom of an underlying condition, and not all those conditions cause hair loss directly. Aggressively scratching the scalp damages the hair follicles while the underlying scalp condition affects the structure or strength of the hair follicles and causes hair loss.
Causes Of Itchy Scalp Leading To Hair Loss
The following conditions can cause an itchy scalp and hair loss:
- P.Capitis Simplex: Commonly called dandruff, this condition results in itching and small white flakes on the scalp and shoulders.
- Seborrheic Dermatitis: Like dandruff, seborrheic dermatitis causes itchy skin on any area of the body along with yellow greasy flakes and redness. When it affects the scalp, it causes hair loss because of the inflammation and irritation of hair follicles.
- Tinea Capitis: Ringworm causes rings with raised bumps on the skin, making it dry and itchy. When it affects the scalp, the fungal infection damages the hair shafts and leads to their brittleness; thus they break off easily leaving a bald patch of skin.
- Lichen Planopilaris: It is a skin condition that can cause itching and burning sensation in its acute phase followed by purplish papules, follicular plugging and scarring hair loss.
- Psoriasis: An autoimmune disorder that can affect all areas of the body including the scalp. It causes the formation of white or silvery scales over underlying red and inflamed itchy patches or plaques.
- Allergic Reactions: When chemical products such as hair dyes, hair gels, hairspray and mousse do not suit your skin, the resultant allergic reaction may cause an itchy scalp and hair loss.
- Sensitive Scalp: Tingling, burning or prickling sensations with or without pain or itching due to variations in pollution, stress or hormone levels characterise sensitive or reactive skin.
- Environmental Factors: Cold temperatures cause the scalp skin to become dry and itchy, or high humidity levels result in an itchy or oily scalp and eventually cause hair loss.
- Head Lice Infestation: Head lice are parasites. Lice infestations are immensely itchy and induce vigorous scratching.
- Improper Hair Care Routine: A lack of hair care hygiene can cause dirt and grease to build up and block hair follicles, resulting in an itchy and smelly scalp. Over time, it damages the hair follicles and causes hair loss.
