Hair growth supplements are a huge market, but only a few nutrients have real evidence behind them. Here’s what genuinely supports healthy hair — and what to be sceptical of.
Cover the basics first
Hair is sensitive to overall nutrition. Low iron, low protein, crash dieting and stress are common causes of shedding in women. A balanced diet, enough protein, and addressing iron often matter more than any ‘hair’ supplement.
Nutrients that support hair
Biotin, zinc, vitamin D and the amino acids in collagen all play roles in healthy hair. A daily multivitamin covers many of these bases in one go.
Be patient — and realistic
Hair grows slowly, so give any change at least three to six months. And remember: supplements help most when you’re filling a genuine gap. Spotting the myths around hair loss helps you avoid wasting money.
