A sudden bald patch: what should you do first?

Updated: 2026-10-06

Alopecia areata · Patchy hair loss

One or more sudden bald patches should be assessed by a doctor or dermatologist. The everyday term “patchy hair loss” can describe different conditions, including alopecia areata and infections, which need to be distinguished.

How is alopecia areata linked to the immune system?

Alopecia areata is an autoimmune form of hair loss: the immune system mistakenly attacks hair follicles, causing hair loss in affected areas. This does not necessarily mean the follicles are permanently damaged. It is not caused by failing to wash your hair properly.

Does stress always cause alopecia areata?

No. Some people develop alopecia areata after significant stress or a life event, but many cases have no clear trigger. There is no need to blame yourself for losing hair, and a busy period at work alone cannot establish the cause.

Can the hair grow back?

It can. Some people experience regrowth, but the timing, extent and likelihood of further hair loss vary. A steady routine and gentle hair care can support everyday comfort, but cannot guarantee recovery from alopecia areata.

How can Lavender Hair help you understand the next step?

You can book a free scalp check for a magnified look at your hair, scalp surface and follicle openings, and discuss changes in density and everyday comfort. Our team will explain suitable gentle care. If your needs fall outside our care services, we will not push a treatment. If you are already receiving medical treatment, bring your current instructions so everyday care can fit around them.

What can I do at home?

Start with a few everyday habits

  • Avoid repeatedly pulling or rubbing the same area, and keep hairstyles loose.
  • Take photographs in similar lighting and from similar angles. There is no need to keep zooming in and checking every day.
  • Keep washing and care gentle. Everyday care mainly supports comfort; it is not a treatment that makes alopecia areata resolve on its own.

Frequently Asked Questions

Common Questions, Clear Answers

Start with the essentials, then explore what they mean for your circumstances.

Can massage alone regrow hair lost to alopecia areata?

No such promise can be made. Massage and everyday hair care cannot replace treatment for alopecia areata. The right approach depends on the actual cause.

Can a scalp check at 50 to 200 times magnification diagnose alopecia areata?

Images alone cannot establish a diagnosis. They help show visible scalp and hair features; medical assessment belongs with a doctor.
