Pattern hair loss does not happen all at once - it miniaturises follicles stage by stage over years.
Pattern hair loss does not happen all at once - it miniaturises follicles stage by stage over years. Knowing the stages matters for one reason: treatment preserves existing hair far better than it revives dead follicles. Every stage earlier is money and hair saved.
Each stage is follicles shrinking: thick terminal hairs become thin, short, colourless "vellus" hairs, then the follicle goes dormant. Dormant follicles can be coaxed back for a window of time; long-fibrosed ones cannot. That is the entire case for early treatment, per NHS hair loss guidance.
Areata does not follow these scales. Its stages are: sudden patch appearance → possible expansion or multiplication over weeks → spontaneous regrowth (common, especially with few small patches) or, in a minority, progression to totalis/universalis. Unpredictability is its defining feature.
The classical texts describe Khalitya as a slow Pitta-led burn: first hair quality degrades (dryness, thinning, loss of lustre), then density falls, then the scalp becomes visible - a staged attrition matching modern observation. They also make the practical point bluntly: neglected early disease becomes Krcchra-sadhya (hard to treat) and eventually Asadhya (beyond treatment) - their way of saying "early intervention or nothing."
How fast does pattern baldness progress? Years to decades per stage, varying by genetics. Rapid visible loss over months suggests an added cause (thyroid, iron, stress) worth checking.
Can a stage reverse? Early stages can genuinely thicken with treatment (minoxidil, finasteride for men). Late shiny-bald stages do not regrow - transplantation is the only option there.
Does hair loss stabilise on its own? Pattern loss usually slows with age but rarely stops completely. Telogen effluvium, by contrast, halts once the trigger passes.
What stage is "too late" for treatment? When the scalp is shiny and poreless - follicles are gone. A dermatologist can assess remaining follicle density in one visit.
