SHAMPOO FOR HAIR GROWTH

CLAIM: These contain vitamins, proteins and herbs, which the maker says ‘encourage blood flow to the scalp for faster hair growth’.
EXPERT VERDICT: ‘Independent research found that the proteins here — cystine, cysteine and methionine — can help with hair growth if you are deficient in these,’ says Iain Sallis. ‘But these studies were done with oral supplements. I’ve not seen good evidence to show a shampoo can make your hair grow faster. I can’t find details on the maker’s trials in which it claims that “100 per cent of users had increased hair growth after 84 days” — even the links on its own website don’t work.’
