Patchy hair loss has several possible causes. Alopecia areata is one example, but a patch does not identify the condition. A GP or dermatologist should assess it before a cosmetic procedure.
Why does the shape not give the whole answer?
Alopecia areata can produce rounded areas of hair loss, but not every bare patch has that cause. The skin, the way the change developed and any hair changes elsewhere can help a healthcare professional decide what assessment is needed.
What should I tell the clinician?
Mention when the patch appeared, whether it is changing and whether you have itching, scaling, soreness or other new symptoms. Also mention any change in eyebrows, eyelashes or other body hair. Existing photographs can help describe timing, but are optional.
How does this affect a clinic visit?
Do not book PRP, microneedling or another scalp procedure as a substitute for diagnosis. Once you have medical advice, you can discuss any appropriate supporting care and whether the clinic has a role. A medical assessment may be the most useful next step even if you initially hoped to book a treatment.
Will the patch definitely grow back?
That cannot be promised. Outcomes depend on the cause and individual circumstances; even a named diagnosis does not guarantee a particular result.
Can I use the guided form?
Yes, for general information. Choose the option that describes patchy or sudden loss so the journey can explain why medical assessment should come first.
A conversation starts with you.
You can ask us about the clinic without committing to treatment. A GP or dermatologist assessment comes first for unexplained patches, pain or inflammation; any later clinic conversation can take that advice into account.
