How long until visible hair changes?

Shedding often improves first; visible density changes usually require 4-9 months of consistent adherence.

Do ferritin and thyroid really affect hair?

Yes. Low ferritin and thyroid dysfunction are common systemic drivers and should be corrected before declaring treatment failure.

Is this protocol only for men?

No. We use different pathways for men and women, but both require baseline pattern classification and lab context.

Best fit

Who this protocol is built for.

We screen eligibility before any prescription enters the conversation. Decline is treated as an outcome, not a failure.

Men with androgenic thinning and elevated DHT sensitivity
Women with diffuse shedding where ferritin/thyroid may be involved
Members seeking provider-reviewed alternatives to random topical stacking

Contraindications

Who should avoid this path.

These are hard stops. We route into a different protocol or refer out, rather than working around a contraindication.

Scarring alopecia concerns requiring dermatologist biopsy first
Active pregnancy or conception planning when systemic agents are contraindicated
Unwillingness to run baseline ferritin and thyroid labs

Execution

Phased protocol timeline.

Each phase has explicit entry criteria, actions, and exit conditions. The plan moves on data and tolerance, not a calendar.

Phase 01
Weeks 0-3
Identify pattern and drivers
Distinguish androgenic pattern loss from systemic shedding contributors.
- Run ferritin, CBC, thyroid panel, and androgen context where indicated
- Document pattern and progression with baseline photo protocol
- Select scalp and systemic options based on contraindication profile
Phase 02
Weeks 4-16
Initiate treatment stack
Begin route-specific pharmacologic and behavioral regimen with adherence tracking.
- Start topical or oral strategy under provider guidance
- Layer protein and micronutrient correction where labs support it
- Use monthly photo and symptom logs for objective trend review
Phase 03
Weeks 17-36+
Evaluate durability
Assess response quality and decide continuation, escalation, or switch.
- Recheck ferritin and thyroid when abnormal at baseline
- Review side effects and dose tolerability
- Plan long-run maintenance to prevent rebound shedding
