A patch of hair loss on the scalp that is slowly increasing in size is often due to alopecia areata, where the body's immune system temporarily affects the hair roots, causing smooth, round bald areas; however, a fungal infection of the scalp can sometimes look similar, so a proper check by a doctor is important. The good news is that this condition is usually treatable, and hair can grow back in many cases. Doctors commonly prescribe medicated lotions or mild steroid creams, and sometimes small injections in the affected area to reduce inflammation and help regrowth. If a fungal infection is found, antifungal medicines are given instead. Along with treatment, try to avoid scratching or applying random products, keep the scalp clean, eat a balanced diet, and manage stress, as it can sometimes worsen hair loss. Early treatment gives better results, so it is best to consult a dermatologist for the right diagnosis and care.

If you have alopecia areata and are noticing white hair growing in the affected areas, it usually means that the hair is starting to regrow, but the pigment (colour) has not fully returned yet. This is a positive sign and is often seen during recovery. Alopecia areata happens when the body's immune system temporarily affects the hair roots, leading to patchy hair loss, but it is not an infection and is not contagious. Management focuses on helping hair regrow and preventing further loss. A doctor may prescribe medicated solutions or mild steroid creams, and in some cases, small injections in the patch to reduce inflammation. Maintaining good general health, managing stress, and avoiding irritation to the area can also support recovery. In many people, hair regrows over time, though the condition can sometimes come and go. It is best to follow up with a dermatologist regularly to monitor progress and adjust treatment if needed.
