Thinning hair is something most women will have to face at some point - some sooner than others. Katie Price and Britney Spears have both been caught flashing bald patches - probably caused by excessive use of extensions and over styling - while older celebrities such as Sharon Stone and Halle Berry have also been papped looking a little 'thin up top.' "As you age, your hair loses moisture, acids and protein, which can lead to thinning," explains Aneta Mortlock, UK managing director at John Masters Organics. "There are various ways you can replenish these such as drinking soya milk, for the soy protein, which will strengthen hair. You can also replenish Linolenic acids by making a home hair mask with avocado and essential oils. Apply directly to hair and leave for half an hour." Additionally, try to use a conditioning treatment once a week - John Masters Organics hyaluronic acid-rich Honey & Hibiscus Hair Reconstructor (ciao.co.uk) works wonders on all hair types, but is especially ideal for older hair.
