Hair loss treatment in Klang: a sensible first step

Discovering a round, smooth bald patch can be alarming. It is often noticed by a barber, a hairdresser or a family member. Patchy hair loss has several possible causes, and some need prompt treatment. If you live in Klang or elsewhere in Selangor, this guide explains the common causes, how they differ, and when to seek help quickly. For a full overview of the condition, see alopecia areata.

Alopecia areata

Alopecia areata is an autoimmune condition in which the immune system attacks hair follicles, causing hair to fall out, often in round or oval patches ¹. It can affect the scalp, beard, eyebrows, eyelashes and body hair. It can occur at any age, in both children and adults ².

Typical features include:

• One or more smooth, round patches of hair loss
• Skin in the patch that usually looks normal, without scaling
• Sometimes short broken hairs at the edge of the patch, which narrow towards the scalp
• Nail changes, such as small pits, in some people ³

The course is unpredictable. Hair may grow back on its own, sometimes within months, but new patches can appear ¹. In some people, the condition becomes more extensive ⁴.

Scalp ringworm (tinea capitis)

Scalp ringworm is a fungal infection. It is more common in children but can affect adults ⁵. Unlike alopecia areata, the scalp often looks abnormal:

• Scaly, itchy or inflamed patches
• Broken hairs, sometimes appearing as black dots
• Sometimes swollen, tender, pus-filled areas
• Swollen glands in the neck in some cases ⁶

Ringworm is contagious and needs antifungal treatment from a doctor, usually tablets for the scalp. Creams alone are often not enough ⁷. Avoid sharing combs, towels or hats until it is treated.

Other causes of patchy loss

• Traction alopecia: from tight hairstyles or headwear, usually along the hairline ⁸
• Hair pulling (trichotillomania): irregular patches with broken hairs of different lengths ⁹
• Scarring alopecias: such as lichen planopilaris, where the skin may be red, scaly or shiny and the openings of hair follicles are lost ¹⁰
• Scalp psoriasis or seborrhoeic dermatitis: usually with flaking and itch rather than smooth patches ¹¹

Signs that need prompt medical attention

See a doctor soon, rather than waiting, if you notice:

• A painful, swollen, pus-filled or crusted patch, especially with fever or swollen neck glands
• Scaly patches with broken hair in a child, or several family members with similar patches
• Rapid spread, with many new patches or loss of most scalp hair
• Loss of eyebrows or eyelashes
• A red, shiny or scarred-looking patch, since early treatment of scarring conditions may help limit lasting damage
• Hair loss with other symptoms, such as unexplained weight loss, rash, mouth ulcers or joint pain

What a doctor may do

A doctor will examine the scalp and may use a magnifying tool called a dermatoscope. If infection is suspected, a sample of hair or scale may be taken for testing. Blood tests or a scalp biopsy may be suggested in some cases ¹². You may be referred to a dermatologist. You can check that a doctor is registered with the Malaysian Medical Council ¹³.

Treatment for alopecia areata

Treatment aims to encourage hair growth and depends on how much hair is affected:

• Steroid injections into small patches are commonly used ¹²
• Topical steroids or other topical treatments may be used
• Other treatments for more extensive disease may be considered by a dermatologist
• JAK inhibitors are a newer group of medicines studied for severe alopecia areata, prescribed under specialist care ¹⁴

A Cochrane network meta-analysis compared treatments for alopecia areata and found that JAK inhibitors probably help some people with severe disease, while the evidence for many other treatments was very uncertain ¹⁵. Some people choose not to treat small patches and wait to see if hair grows back.

Coping and support

Alopecia areata can affect self-esteem, especially when it is visible. Wigs, scarves, hats, brow pencils and other camouflage options can help some people feel more comfortable. Talk to your doctor if you feel anxious or low.

The bottom line

A bald patch in Klang is most often alopecia areata, but ringworm, traction, hair pulling and scarring conditions can look similar. If the patch is scaly, painful, spreading quickly or affects a child, see a doctor promptly. For first steps with any sudden change, read what to do first when your hair starts falling.
