L'ANZA claim their Trauma Treatment will heal over-processed hair and extend the longevity of hair colour by up to 107%.

It can also be used before dye to help improve colour attachment.

The treatment can be left in or rinsed out and used weekly or daily if your hair is in serious trouble. If using before highlights, the advice is to leave it in.

I found it works best rinsed out and it left my hair feeling silky smooth.

It's probably one of the best conditioning treatments I've ever used, almost comparable to the effects of a keratin blow-dry.

My highlights also seemed refreshed and one person asked if I'd had my colour done.

Verdict - a fab five stars.
