Hair loss that doesn’t add up can feel confusing and unsettling
You may be shedding more hair than usual, noticing thinning at the crown, or dealing with sudden changes in your skin, weight, or mood. Often, the instinct is to blame stress or genetics and move on. But in many cases, these changes are signals of an underlying hormonal shift. One hormone that frequently sits at the centre of both hair loss and broader hormonal concerns is DHT.Understanding when to test DHT is not about reacting to hair fall alone. It is about identifying whether a deeper hormonal imbalance is silently driving the problem and deciding if medical evaluation is actually necessary.
What exactly is DHT and why does it matter for hair and hormones?
DHT, or dihydrotestosterone, is a hormone derived from testosterone. In the body, an enzyme called 5-alpha reductase converts testosterone into DHT. While DHT plays an important role in sexual development, excess or heightened sensitivity to it can disrupt hair growth and hormonal balance.In the scalp, DHT binds to hair follicles and gradually shrinks them. Over time, this process shortens the hair growth cycle, produces thinner strands, and eventually leads to visible hair thinning or baldness. This mechanism is most commonly associated with androgenetic alopecia in men and women.
From a hormonal health perspective, DHT imbalance may coexist with conditions such as PCOS, thyroid dysfunction, metabolic stress, or chronic inflammation. This is why hair loss is often an early, visible symptom of deeper internal changes.
When hair fall becomes a reason to consider a DHT test
Not all hair loss needs hormonal testing. Seasonal shedding, postpartum hair fall, or short-term stress-related hair loss often resolve once the underlying trigger settles. A DHT test becomes relevant when hair fall shows specific patterns or persistence.You may need to consider a DHT test if:
- Hair thinning is progressive and concentrated at the crown, temples, or mid-scalp
- There is a strong family history of pattern hair loss
- Hair fall continues despite correcting diet, stress, and basic deficiencies
- You notice widening of the part in women or a receding hairline in men
- Hair strands are becoming visibly finer over time
These patterns suggest follicular sensitivity to androgens rather than temporary shedding.
Hormonal symptoms that make DHT testing more relevant
Hair loss rarely exists in isolation when hormones are involved. Certain systemic signs raise the likelihood that DHT or related hormonal pathways may be contributing.A DHT test may be clinically relevant if hair loss is accompanied by:
- Acne or oily skin that persists beyond adolescence
- Irregular menstrual cycles or PCOS symptoms in women
- Sudden weight gain or difficulty losing weight
- Reduced energy levels or chronic fatigue
- Changes in libido or mood fluctuations
In such cases, DHT testing is usually considered alongside other hormonal markers rather than alone.
What dermatologists look for before recommending a DHT test
From a dermatological perspective, DHT testing is not the first step. A dermatologist typically evaluates scalp pattern, hair shaft diameter, miniaturisation, and family history before suggesting blood tests.DHT testing is most useful when:
- The clinical pattern strongly suggests androgen-driven hair loss
- Topical or nutritional interventions are not yielding expected results
- Medical treatments that influence hormonal pathways are being considered
Dermatologists often interpret DHT values in context. Normal-range DHT levels can still cause hair loss if follicles are genetically sensitive to the hormone.
How Ayurveda interprets DHT-driven hair loss
Ayurveda does not describe DHT as a standalone entity but recognises its effects through concepts like pitta imbalance, excess heat, and disturbed dhatu nourishment. Hair is considered a byproduct of asthi dhatu, and when metabolic fire or hormonal heat becomes excessive, hair health suffers.From an Ayurvedic lens:
- Excess internal heat can accelerate hair thinning
- Poor digestion and absorption weaken follicle nourishment
- Chronic stress aggravates hormonal imbalance and hair loss
This perspective explains why hair loss linked to hormones often improves only when digestion, stress, sleep, and metabolic balance are addressed together.
The nutritionist’s view on DHT and hair loss
Nutrition alone cannot switch off DHT, but it plays a crucial role in how the body handles hormonal signals. Poor nutrient absorption, iron deficiency, and chronic inflammation can amplify the impact of DHT on hair follicles.A nutritionist typically evaluates:
- Protein and micronutrient sufficiency
- Iron, zinc, and B-vitamin status
- Gut health and digestion efficiency
Optimising nutrition supports follicle resilience and can reduce the severity of DHT-related hair thinning when combined with medical guidance.
Should everyone with hair loss get a DHT test?
No. Testing without clinical indication often leads to confusion rather than clarity. Many people have normal DHT levels and still experience hair loss due to stress, nutritional deficiencies, thyroid imbalance, or gut-related issues.A DHT test is most valuable when:
- Hair loss follows a clear androgenetic pattern
- Hormonal symptoms coexist with hair changes
- A clinician is considering targeted hormonal or dermatological intervention
Testing should always be interpreted by a qualified professional rather than used as a standalone diagnostic tool.
How DHT testing fits into a root-cause-first approach
Hair loss is rarely caused by a single factor. DHT is one piece of a larger physiological puzzle that includes metabolism, hormones, stress response, digestion, and nutrient delivery to the scalp.A root-cause-first approach uses DHT testing selectively, not reactively. The goal is to understand whether DHT is a primary driver or a secondary contributor, and then address the internal imbalance rather than only the visible symptom.
Frequently asked questions about DHT testing
Can DHT levels be normal and still cause hair loss?
Yes. Hair follicles can be genetically sensitive to DHT even when blood levels fall within the normal range.Is DHT testing useful for women?
Yes, especially in cases of PCOS-related hair thinning, persistent acne, or hormonal imbalance. However, it is usually done alongside other hormone tests.Does lowering DHT always stop hair loss?
Not always. Hair loss may continue if other root causes such as stress, poor digestion, nutrient deficiencies, or thyroid imbalance are not addressed.Can lifestyle changes alone manage DHT-related hair loss?
Lifestyle changes support hormonal balance but may not be sufficient in moderate to advanced androgenetic hair loss without medical supervision.Read More Stories:
