Hair Health
Understanding hair from the follicle and its cycle
Hair health comes down to one idea: hair is not a permanent fibre but an organ that grows, rests and regrows in cycles. Most hair loss, whether thinning, a sudden shed or autoimmune patches, is a disruption of that cycle. Understanding which disruption is at play, and whether the follicle is still alive, is what guides care.
Three phases, several disruptions
Each follicle runs a three-phase cycle: a years-long growth phase, a brief transition, and a resting phase that ends when the hair sheds. Losing dozens of hairs a day is simply this cycle turning over. Hair loss happens when follicles shrink and shorten the cycle, shift into resting all at once, or are attacked by the immune system, each behaving very differently.
Understanding hair health
Across this family, the common question is what disrupted the cycle, and whether the follicle survives. Genetics and hormones drive gradual thinning, a shock to the body drives a temporary shed, and the immune system drives patchy loss. A few causes destroy the follicle for good. Sorting which one is present comes before any treatment.
Pattern thinning, genetic and hormonal
On an inherited, DHT-sensitive terrain, certain follicles shrink a little more each cycle, producing finer, shorter hairs. This androgenetic thinning is slow and progressive, tracing a receding hairline and crown in men and a widening part in women. Because the follicles are alive but weakening, acting early offers the most to work with.
A diffuse shed after a shock
A shock such as childbirth, illness, rapid weight loss, iron deficiency or major stress can push many follicles into resting phase at once. The diffuse shedding shows two to three months later. This form is usually temporary and reverses once the cause is found and corrected, which is why identifying it matters before treating.
Autoimmune and scarring loss
Sometimes the immune system attacks growing follicles, leaving smooth round patches where the follicle is paused, not destroyed. More rarely, inflammation destroys the follicle and replaces it with scar tissue, which does not regrow. Both are medical situations that need diagnosis, not a cosmetic fix.
Lashes, brows and the rest
Lashes and brows are hairs too, with a much shorter cycle, so they thin from wear, age or sometimes a medical cause. Across all of these, the dividing line is the same: a living follicle can still respond, a destroyed one cannot, which is why a diagnosis comes first.
How to Prevent
Hair concerns we address
Hair Loss
An umbrella term for very different causes, from gradual pattern thinning to a sudden diffuse shed, autoimmune patches or scarring. Because each behaves differently, sorting the type guides everything that follows.
Thinning Hair
A gradual loss of density, usually the early face of pattern hair loss, where DHT-sensitive follicles shrink and produce finer, shorter hairs with each cycle. Acting early, while follicles are alive, helps most.
Alopecia Areata
An autoimmune form of hair loss in smooth, round patches, where the immune system pauses the follicle without destroying it. Its course is unpredictable, regrowth is possible, and it is diagnosed and managed medically.
