Gradual, even reduction in hair density across the whole scalp — not a receding hairline, but a slow decrease in volume and coverage that affects both men and women.
Unlike male pattern baldness or female pattern hair loss, diffuse thinning does not follow a predictable recession pattern. The cause is often internal — hormonal, nutritional or stress-related — and identifying it is the first step to effective treatment.
DHT sensitivity causes follicle miniaturisation across the scalp rather than at specific zones. The most common cause in both men and women.
A sudden shock to the system — illness, surgery, rapid weight loss, childbirth — pushes a large number of follicles into the resting phase simultaneously, causing widespread shedding 2–4 months later.
Low ferritin (iron stores), B12 deficiency or inadequate protein intake are common and reversible causes. A simple blood panel can identify these.
Both hypothyroidism and hyperthyroidism can cause diffuse shedding. Thyroid-related hair loss typically responds well to treating the underlying condition.
Prolonged psychological stress elevates cortisol, which can disrupt the normal hair growth cycle and cause extended telogen phases across the scalp.
Blood thinners, antidepressants, contraceptives and certain blood pressure medications can all cause diffuse thinning as a side effect.
The distinction matters because diagnosis determines treatment. Diffuse thinning often has a reversible underlying cause — pattern hair loss typically does not.
A hair transplant will not work if the underlying cause of diffuse thinning has not been identified and treated. DrQ will not recommend surgery until medical causes have been investigated and ruled out.
Treatment depends entirely on identifying the cause. The pathway below reflects the clinical approach DrQ takes at assessment.
Ferritin, B12, thyroid panel, hormone levels (DHEA-S, testosterone, prolactin in women) and full blood count. Many reversible causes are identified here. DrQ reviews results as part of your assessment.
Iron supplementation, thyroid medication, stopping a causative drug, or managing stress. Without this step, no topical treatment or surgery will produce lasting results.
5% topical or oral low-dose minoxidil extends the growth phase of the hair cycle and can meaningfully improve density in diffuse thinning. Most effective when combined with addressing the underlying cause.
For androgenetic diffuse thinning in men, DHT-blocking medication can slow or halt progression. Not suitable for all patients — discussed at consultation.
Growth factor injections directly into the scalp can stimulate miniaturised follicles and improve density. Often used alongside medical treatment for diffuse thinning.
Considered only when the pattern of loss is stable, the underlying cause has been addressed, and there is sufficient donor supply. Diffuse thinning patients require careful donor assessment — the donor area may itself be affected by the same diffuse process.
Send DrQ a photo and describe your pattern of loss. He will reply personally with an honest opinion on likely cause, next steps, and whether you are a candidate for any treatment.
