Fess up: we know more than a few of you will have tried putting lemon juice on your hair…

Lemon juice itself cannot cause your hair to change colour, it needs the sun. It is the acidity in the lemon juice which helps speed up this process.

However, sitting in the sun with lemon in your hair only works for blondes, who may see some lightening of the hair. If you have darker hair it may only turn slightly red.

The science is that UV rays cause internal reactions with the hair, impacting the pigment. UV can also be damaging (eek) breaking down important proteins within your hair, making it weaker.

So, sorry to the fans of using lemon juice in their hair: we’re calling this one a hair myth.
