Hair loss can develop in different patterns and through different mechanisms. Some forms affect the hair-growth cycle, some involve progressive changes to the follicle, and others may be related to inflammation, autoimmunity, repeated tension or behaviour.
There can also be underlying factors that contribute to increased shedding or changes in hair growth.
Understanding the pattern helps us ask better questions about what may be happening and what should happen next.
Androgenetic alopecia, also known as pattern hair loss, usually develops gradually. You may notice your part becoming wider, your ponytail feeling smaller, or more scalp showing through than it used to. Genetics can create a predisposition to pattern hair loss, but having that predisposition does not necessarily mean it will present in the same way, at the same age, or to the same degree in everyone. Gene expression is influenced by a much bigger biological picture, including hormonal signalling, age, health, environment and other epigenetic influences. That’s why I look beyond genetics alone and consider the pattern, timeline and what may be influencing the follicle.
Increased shedding that occurs when more hairs than usual shift into the resting and shedding phases of the hair-growth cycle. It can become noticeable months after a triggering event, which is one reason connecting the timeline matters.
An autoimmune form of hair loss where the immune system mistakenly targets the hair follicle, often causing smooth, round or oval areas of hair loss. While these patches are one of the more recognizable signs, alopecia areata doesn’t always look the same from person to person. The pattern, location and extent of hair loss can vary, which is why understanding what you’re actually seeing matters.
A group of inflammatory hair-loss conditions in which hair follicles can become permanently damaged or destroyed. Early medical assessment is particularly important when a scarring alopecia is suspected.
Hair loss associated with repeated or prolonged tension on the hair and follicles, often related to hairstyles or styling practices. When recognized early, removing the source of tension may help prevent further damage; prolonged traction can lead to permanent loss.
A condition involving recurrent urges to pull out one's own hair, which can result in areas of broken hairs and hair loss. Because there is a behavioural and psychological component, appropriate support may extend beyond hair and scalp care.
Not every contributing factor is itself a type of alopecia. Hormonal, nutritional and health changes can influence the hair-growth cycle or contribute to shedding and changes in hair quality.
That distinction is important.
Changes associated with postpartum recovery, menopause, PCOS, thyroid disorders and other endocrine factors may influence hair growth or shedding. The pattern, timing and wider health context help determine whether medical investigation may be appropriate.
Nutritional status can influence normal follicle function and hair-fibre formation. When a deficiency is suspected, the goal isn't to blindly supplement—it is to determine whether further nutritional or medical investigation is warranted.
