Adrenal androgen excess is responsible for up to 20% of female pattern hair loss cases, yet it is frequently overlooked. While PCOS gets most of the attention in discussions of androgen-driven hair loss, the adrenal glands are a separate source of androgens that can miniaturize follicles through a distinct mechanism. Identifying and tracking the adrenal component matters because the treatment approach differs from ovarian-driven hair loss.
Understanding Adrenal Androgens and Hair
The adrenal glands sit atop your kidneys and produce DHEAS (dehydroepiandrosterone sulfate), which is the most abundant circulating androgen in women. DHEAS itself has weak androgenic activity, but it is converted to testosterone and DHT in peripheral tissues, including the hair follicle.
When Adrenal Androgens Become a Problem
Normally, adrenal DHEAS levels range from 35-430 mcg/dL in premenopausal women (declining with age). Levels above 400-500 mcg/dL in premenopausal women warrant investigation for adrenal pathology.
The most common cause of adrenal androgen excess is non-classic congenital adrenal hyperplasia (NCAH), a genetic condition affecting 1-5% of women depending on ethnicity. NCAH is caused by partial deficiency of the enzyme 21-hydroxylase, which diverts adrenal steroid production toward androgens.
Other causes include:
- Adrenal tumors (rare, usually cause very high DHEAS > 700 mcg/dL)
- Cushing's syndrome (elevated cortisol with secondary androgen effects)
- Chronic stress (mild DHEAS elevation through HPA axis activation)
- Idiopathic adrenal androgen excess (elevated DHEAS without identifiable pathology)
Distinguishing Adrenal From Ovarian Sources
The diagnostic blood panel is the key differentiator:
| Lab Marker | Adrenal Source | Ovarian Source (PCOS) | Mixed Source |
|---|---|---|---|
| DHEAS | Elevated (>400 mcg/dL) | Normal or mildly elevated | Elevated |
| Total testosterone | Normal or mildly elevated | Elevated | Elevated |
| Free testosterone | Normal or mildly elevated | Elevated | Elevated |
| 17-OH progesterone | Elevated in NCAH | Normal | May be elevated |
| LH/FSH ratio | Normal | Often > 2:1 | Variable |
| Fasting insulin | Normal | Often elevated | Variable |
If your DHEAS is elevated but testosterone is normal, the adrenal glands are the primary androgen source. If both are elevated, you may have a mixed adrenal and ovarian picture.
Treatment Options for Adrenal Androgen Hair Loss
Low-Dose Glucocorticoids
For confirmed NCAH, low-dose dexamethasone (0.25-0.5mg at bedtime) or prednisone (2.5-5mg at bedtime) suppresses the adrenal ACTH drive that overproduces androgens. This can normalize DHEAS levels within weeks.
Tracking note: DHEAS levels may normalize quickly (4-8 weeks), but hair density improvement takes 6-12 months because follicle miniaturization reverses slowly.
Spironolactone (100-200mg)
Spironolactone blocks the androgen receptor at the follicle, regardless of whether the androgens come from the ovaries or adrenals. This makes it effective for adrenal androgen hair loss even without addressing the source.
Combined Oral Contraceptives
COCs increase SHBG production by the liver, binding more free testosterone and reducing its availability to follicles. They provide modest DHEAS suppression through ovarian-adrenal feedback loops.
Combined Approach
For maximum hair benefit, the most effective strategy is often:
- Address the source: Low-dose dexamethasone for NCAH (or manage the underlying adrenal condition)
- Block the receptor: Spironolactone at 100-200mg
- Reduce free androgens: COC with anti-androgenic progestin (drospirenone or cyproterone acetate)
Setting Up Your Adrenal Androgen Tracking Protocol
Step 1: Comprehensive Baseline With Labs
Your baseline should pair density measurement with a complete androgen panel:
Density data:
- Photos from 5 angles under consistent lighting
- AI density analysis at myhairline.ai
- Current Ludwig scale stage
- Note areas of greatest thinning (adrenal androgen hair loss can present with frontal thinning or diffuse thinning)
Lab values (morning fasting draw):
- DHEAS
- Total testosterone
- Free testosterone
- 17-hydroxyprogesterone (screens for NCAH)
- Cortisol (morning)
- SHBG
- ACTH (if Cushing's is a concern)
Step 2: Monthly Density Tracking for 6 Months
After starting treatment, track monthly to capture the response curve:
- Weeks 2-6: DHEAS levels may begin dropping (if on glucocorticoids). No visible hair changes yet.
- Months 2-3: Shedding may begin to decrease. Log daily hair count or subjective shedding score.
- Months 4-6: New vellus growth may become visible. Density measurements should begin trending upward.
At each session, record all medications, doses, and any side effects. Note stress levels and sleep quality, as these affect adrenal function.
Step 3: Quarterly Lab-Density Pairing
Every 3 months, pair your density session with repeat labs (at minimum: DHEAS, total testosterone, free testosterone). Plot both on the same timeline:
- DHEAS declining + density stable or improving = treatment working
- DHEAS declining + density still declining = possible concurrent genetic FPHL or additional factors
- DHEAS not declining + density declining = treatment insufficiency, dose adjustment needed
Step 4: Long-Term Monitoring
Once DHEAS levels are controlled and density has stabilized, shift to quarterly tracking with annual comprehensive labs. Return to monthly tracking if:
- DHEAS levels rise on repeat testing
- You experience increased shedding
- You change medications
- You are under significant stress (adrenal androgens are stress-responsive)
The Stress Connection
Adrenal androgens are uniquely stress-sensitive. Unlike ovarian androgens, DHEAS production increases when the hypothalamic-pituitary-adrenal (HPA) axis is chronically activated. This means that sustained psychological or physical stress can drive adrenal androgen-mediated hair loss even in women without NCAH or other pathology.
If your tracking data shows density dips that correlate with high-stress periods (job change, relationship stress, illness, sleep deprivation), you may have a stress-adrenal-hair connection worth discussing with your endocrinologist. Logging stress levels at each tracking session adds a valuable data layer.
Document Your Adrenal Androgen Hair Recovery
Adrenal androgen hair loss responds to targeted treatment, and the response is measurable. Upload your photos to myhairline.ai/analyze to establish your baseline and begin building the lab-density correlation that guides your treatment optimization.
