Zero budget for an in-salon treatment? Try this homemade recipe...

Is your hairdresser always telling you that boosting your hair's vitamin intake is vital for shine? Grab a small jar of mayo (now isn't the time to think skinny, so go full fat) and half a ripe avo, which is packed with vitamins E and B6.

Blitz in a food processor or mash until the mixture is smooth and minty green in colour. Apply from root to tip (if you have long hair and just need to condition the ends, apply from mid-length to tip), then wrap cling film around your head so your hair is completely covered. Leave for 20 minutes, rinse hair, then wash and condition as usual.

Tip: For extra-deep conditioning, wrap a hot, damp towel around your cling-filmed head and leave for 20 minutes.
