Hair fall and thinning without dandruff can occur due to various reasons, such as nutritional deficiencies, stress, hormonal changes, genetics, or certain health conditions. Lack of hair thickness and poor growth despite trying remedies may be due to underlying causes such as low iron, vitamin D, or vitamin B12 deficiency, thyroid problems, or pattern hair loss. To improve hair growth and thickness, focus on a balanced diet rich in protein, vitamins, and minerals, manage stress, get proper sleep, and avoid excessive use of heat-styling tools or harsh hair products. It is important to identify the exact cause rather than trying multiple remedies without proper guidance. A dermatologist can examine your scalp, assess your hair loss pattern, and recommend tests or treatments, such as topical medications or supplements, if needed.
