What should you know about hair loss at 18?

A gradual change at the temples or crown can occur with male pattern hair loss, while overall reduced density may have other explanations. Alopecia areata can produce smooth patches. Telogen effluvium can follow illness, emotional strain, or a substantial body change. Tight braids, extensions, or repeated tension can cause traction alopecia. Scalp ringworm may cause itch, scale, broken hairs, or tender inflamed areas. A diagnosis should follow examination, not a single symptom.

Photograph the hairline, part, and crown in consistent lighting and note changes in shedding, styling, health, diet, and medicines. Use a gentle routine and avoid pulling, scratching, or harsh processing. Arrange a family doctor or dermatologist visit if the change persists or concerns you. The clinician may inspect follicles and the scalp and decide whether further tests or treatment are needed. Do not borrow prescription products.

Seek prompt assessment for sudden patches, rapid progression, scalp pain, redness, pus, crusting, severe itch, or broken hairs. Get urgent help for facial swelling or serious illness. Emotional distress is also a valid reason to seek support; treatment planning can include how the change affects daily life.

Ask which pattern is present, whether a trigger is likely, whether the scalp needs testing, what treatment choices involve, and how you will judge whether the plan is helping.
