Biotin supplements are widely marketed for hair growth, but the evidence that they help people with normal biotin levels is thin. Biotin is a B vitamin your body needs for normal cell function, and true biotin deficiency can cause hair loss. However, deficiency is rare in healthy adults, and no large, well-controlled human trials have … Read more
Dark patches in the armpits usually come from friction, irritation, or a skin condition called acanthosis nigricans — not from poor hygiene. Removing them means treating the cause, not scrubbing harder. A gentle routine with the right products, plus a doctor’s input when a medical cause is involved, is the realistic step-by-step path.
