When Hair Loss Needs a Dermatologist First
Most pattern hair loss is treatable online. These four are not: patchy loss, scarring signs, rapid shedding, under 18. Women's loss is treated, differently.

Classic male pattern hair loss is one of telehealth's best use cases: a clinical diagnosis, photo-friendly, with proven daily medications. But four presentations do not belong on that conveyor belt, and one of them is genuinely urgent, because delay costs hair that never comes back. [1][2]
A service that prescribes finasteride to every scalp that messages it is not being efficient; it is skipping the sort. Here is the honest referral list: what routes to a dermatologist first, why, and what happens to treatment in the meantime.
What it suggests. Alopecia areata, an autoimmune attack on follicles. It often arrives suddenly, in round or oval patches with otherwise normal scalp skin. [1][2]
Why not the standard prescriptions. Finasteride does nothing for it, and minoxidil alone is not the treatment; areata has its own ladder, from injected steroids to newer systemic options, all specialist territory. [2]
The move. Dermatology referral, with photos attached and the question named. Not a finasteride subscription.
What it looks like. Hair loss plus symptoms: itch, burning, pain, redness, scale, pustules, or skin that looks shiny and smooth where the follicle openings themselves have disappeared. [1][2]
Why it is urgent. Scarring alopecias destroy follicles permanently. What is lost while waiting is not coming back, which makes this the one hair problem where weeks matter. Diagnosis usually needs a biopsy. [2]
The move. Prompt dermatology referral, flagged as suspected scarring alopecia so it is triaged accordingly. Any competent telehealth intake treats these symptoms as a stop sign, not an upsell opportunity.
What it suggests. Telogen effluvium, the whole-scalp shed that follows illness, surgery, crash weight loss, or a new medication by 2 to 3 months, or occasionally a systemic disease showing itself. [1][2]
Why not the standard prescriptions. It usually resolves once the trigger passes, and the useful work is finding the trigger: history plus targeted labs like thyroid, blood count, and iron. [1] Starting finasteride for an effluvium treats the wrong disease.
The move. Workup first, which we can start in chat with lab orders; referral if it does not declare itself.
This one is about the condition, not about age as a rule. We do see people 18 and under, with a parent or guardian's consent. Pattern hair loss is simply not the case for it: finasteride's safety and effectiveness are not established in anyone under 18, and loss that early deserves a specialist's eyes on the diagnosis itself. [3] A teenager on a hair loss subscription is a red flag for the service, not the teenager.
Female pattern loss is not a referral item here. We treat it, and it belongs in the same conversation as everything else on this page. What it is not is the male pathway with the names changed. The differential is broader, hormonal evaluation carries more weight, and the medication choices are different, because finasteride 1 mg carries a men's label and is contraindicated in pregnancy. [1][3] So the assessment is a longer one and the plan looks different, which is a reason to ask rather than a reason to be turned away. One specific scenario, shedding after stopping birth control, is covered in this article.
A referral is a step, not a rejection, and it should come with specifics: who, for what question, with what attached. "Suspected scarring alopecia, photos and symptom timeline enclosed, biopsy question" gets triaged in days; "see a dermatologist" gets a shrug and a three-month wait. That standard is the same one we hold follow-up to, and if your case is the classic pattern after all, treatment starts the same day through the normal assessment.
$80 for the Limited Treatment Plan. If approved, you will receive a 90 day treatment plan with 7 days a week support. Perfect for first time patients who are trying it out.
Or $90 for the Unlimited Membership. If approved, you will receive 3 months of care with 7 days a week support, plus unlimited prescriptions, lab tests, imaging orders, letters and referrals with same day care, cancel anytime, no fees. Perfect for established patients looking for full care.
Our intake asks the sorting questions above before anything is prescribed, and when your case belongs with a dermatologist first, you get told that plainly, with a referral letter that names the question, same day. Message us and we confirm coverage in your state. If yours is the classic pattern, the path starts at how to get a hair loss prescription online.
