Scalp dryness can affect comfort around the follicles, while poor hair condition usually concerns the visible shaft. They can occur together without sharing the same cause. Dry scalp may create tightness, fine flaking, or irritation, whereas dry hair may feel rough, tangled, dull, or brittle. Cleansing habits, weather, styling, scalp disorders, and product reactions can […]

Noticing more hair in a brush, on clothing, or in the shower during certain parts of the year can raise concern. Seasonal hair shedding refers to temporary variation in the number of hairs released as follicles move through their normal growth cycle. Research has reported seasonal patterns in some groups, but timing and intensity vary. […]

Scalp itching can occur without visible dandruff because dryness, product reactions, build-up, friction, inflammatory conditions, infections, infestations, and other factors can create similar sensations. Small flakes may remain close to the scalp or be difficult to notice, so visual inspection cannot identify the cause. Timing, location, recent product changes, skin changes, and hair shedding can […]

Hair oil can create knots when strands already contain tangles or when rubbing, twisting, excess product, and poor sectioning increase friction. Long, dense, curly, damaged, or fine hair may snag more easily if application disturbs its alignment. A careful routine starts before the oil touches the hair. Gentle detangling, controlled sections, modest quantities, smooth hand […]

Hair loses visible shine when its surface becomes rougher, coated, dry, weathered, or uneven. Light reflects most evenly from relatively smooth fibres, so cuticle changes can make previously glossy hair look dull. Washing habits, heat, chemical processing, product residue, hard water, sunlight, friction, and natural hair shape can all alter appearance. However, shine alone does […]

The medulla is the central region found inside some hair shafts. Under a microscope, it may appear as a continuous line, scattered segments, or no visible structure at all. Its presence varies naturally, and a missing medulla does not mean that hair is unhealthy. Researchers have identified possible effects on a fibre’s optical, thermal, and […]

Hair weathering describes the gradual deterioration of a hair strand as grooming, styling, chemical treatments, and environmental exposure wear it down. It often appears first as rough ends, tangles, dullness, or breakage. Although careful care can reduce further damage and improve how hair feels, the visible strand cannot heal itself. Knowing how weathering progresses helps […]

Hair fibres face small stresses every day through washing, drying, brushing, styling, clothing contact, wind, and repeated handling. Individually, these actions may seem minor, yet their effects can accumulate along older lengths and vulnerable ends. Appropriate oil use can help by improving lubrication, reducing friction, and making strands easier to handle. However, oil cannot make […]

The hair shaft contains several structural regions, and the cortex forms a major internal part of most human scalp hair fibres. It sits beneath the protective cuticle and contains organised keratin-based structures as well as melanin pigment. Its architecture contributes substantially to tensile strength, flexibility, elasticity, shape and other mechanical properties. Because the cortex lies […]

Normal hair shedding occurs as individual follicles move independently through their growth cycles. Telogen effluvium involves a noticeable increase in diffuse shedding after more follicles than usual shift away from active growth and progress towards the resting and shedding stages. A significant physiological event or another trigger may precede this change, yet visible shedding often […]
