Can a patient who has been experiencing hair loss for one year regain their previous hair volume?

In general, whether a patient who has been experiencing hair loss for one year can restore their previous hair volume depends on the extent of hair follicle damage and the type of hair loss. If troubled by hair loss, it is recommended to seek medical advice promptly. The specific analysis is as follows:

When hair follicles are not completely closed and the hair loss is reversible, there is potential to regain previous hair volume. For example, alopecia areata caused by high stress or endocrine disorders, or hair loss due to malnutrition, often involves hair follicles that remain active. By timely adjusting lifestyle habits, supplementing nutrients essential for hair growth, and receiving targeted treatments, follicular function may gradually recover, leading to thicker hair and the possibility of returning to normal hair density.

When hair follicles are completely necrotic or the condition involves permanent hair loss, restoring previous hair volume is unlikely. This is commonly seen in androgenetic alopecia, where after one year of hair loss, some follicles may have already lost their activity and the scalp appears smooth. In such cases, because follicular function is permanently lost, new hair cannot grow naturally. Self-regulation or routine care methods are ineffective, and hair volume typically cannot be reversed. Professional medical interventions are required to improve appearance.

Use mild shampoo products when washing hair and avoid scratching the scalp with fingernails. Reduce the frequency of perming and dyeing to prevent chemical damage to hair strands and follicles. Increase dietary intake of protein and vitamin B complex, and consume more eggs, nuts, fruits, and vegetables. Maintain regular sleep patterns, avoid staying up late, keep emotions stable, and reduce mental stress. Gently massage the scalp daily to promote blood circulation and provide sufficient nourishment to hair follicles, supporting healthy hair growth.
