Question

Female 18. ~50kg Diagnosed with AGA and family history of AGA and diabetes (I do not have diabetes) Iron deficiency (diagnosed a year ago, I now have started regularly taking iron supplements for about a month or two since I started noticing hair loss at the nape of neck) and anemic I take Kinecteen ADHD medicine History: AGA hair loss was noticeable in May, went for a dermatology appointment this August when I noticed a wave like shape at the nape of my neck. They only diagnosed me for aga for my temples and hairline, but didn’t say anything about my neck hair loss. I went for another appointment in September and the dermatologist said it couldn’t be ophiasis alopecia because there were too many little hairs, but I’ve been getting anxious because the spot seems to be growing. I feel like hair around my ears is also receding. My nails are more brittle hand are snapping easier. I have noticed the bald area seems to be growing quickly withing a few months/even a few weeks, from just the bottom of my ears to mid/upper ears

Hair loss at the nape that spreads over a few months deserves a proper medical work-up, and the first step is a dermatology visit, not a cosmetic procedure.
When there is no obvious cause such as an infection, a medication, a burn or an injury, hair loss in a new place should be sent to a dermatologist quickly. In your case several things are on the table at once: a family history of pattern hair loss, iron deficiency and anaemia, and a medicine you take regularly. Each of these can thin the hair, and they can add up. The pattern also matters. Pattern loss usually starts at the temples and crown, while loss at the nape or around the ears, or in a wave shape, is sometimes caused by a different condition.
The dermatologist can look at the scalp with a dermoscope, check your iron stores, ferritin, thyroid and other blood values, and repeat the exam after a few weeks to see if the area is really growing. Your doctor said the many small hairs argue against ophiasis, which is useful, but a growing area is a reason to ask for a re-check, not to wait.
Treatment depends on the cause, and nothing here needs to be rushed except the diagnosis. Iron correction takes months to show in the hair, so patience is part of the plan.
I cannot decide this from two photos. If the area keeps spreading, or you notice pain, redness, scaling or pus on the scalp, see your doctor promptly.

I understand why you're feeling anxious, especially when you've noticed the area around your nape and ears becoming more exposed over just a few weeks or months. With your history of androgenetic alopecia (AGA), iron deficiency, and anemia, there are several possible explanations, and it's important not to assume that all of the hair loss is coming from the same condition.

Ophiasis alopecia areata is a pattern of alopecia areata that causes hair loss in a band-like distribution along the sides and lower back of the scalp, often around the nape and behind the ears. The wave-like pattern you're describing can be consistent with this presentation, but it isn't enough to confirm the diagnosis. The presence of small hairs doesn't completely rule it out, as some hairs may be regrowing or breaking off.

Other possibilities include telogen effluvium related to iron deficiency or anemia, progression of your existing AGA, and other inflammatory or scalp conditions. Iron deficiency can contribute to increased shedding, and brittle nails can also occur with iron deficiency, although other causes are possible. However, a sharply defined or progressively expanding area around the nape deserves a closer examination rather than being attributed to iron deficiency alone.

Since you feel the area is enlarging, I would recommend arranging a follow-up with a dermatologist soon. A scalp examination with dermoscopy can help distinguish these conditions. Depending on the findings, your dermatologist may consider blood tests such as a CBC, ferritin, and iron studies, and sometimes thyroid testing or a scalp biopsy if the diagnosis remains uncertain.

Treatment depends on the cause. If alopecia areata is confirmed, corticosteroid treatment may be considered to help control the immune-related inflammation. If iron deficiency is contributing, correcting it under medical supervision is important. AGA may require a separate treatment plan. Continue taking your prescribed iron as directed, and let your doctor know about your ADHD medication rather than stopping or changing it on your own.

The most important point is that progressive hair loss around the nape and ears should be reassessed promptly. Some causes are treatable, and identifying the correct diagnosis early gives you the best chance of managing further hair loss. I wouldn't start multiple hair-loss treatments before clarifying what's happening in that area.
