Summer can really take its toll on our hair. Sun, sea and sand are ideal when it comes to choosing a holiday destination, but for our delicate locks? It's a lethal cocktail.

Hair stylists promise they can rejuvenate your distressed 'do without even picking up a pair scissors thanks to nourishing treatments, but do they really work - or is the damage just disguised by the power of a very good blow dry?

We were sceptical, so we sent our testers.Here's how they got on...

Liz Connor tried: KeraStraight Style Solution, £380 with technical director Zak Twohig at Trevor Sorbie. Available at salons nationwide. Visit KeraStraight.com to find your nearest salon.

"This KeraStraight luxury treatment works by putting keratin - the main protein in skin, hair and nails - and other proteins back into your hair, simultaneously straightening, repairing and smoothing the hair shaft.

"While this treatment isn't cheap, the results last for around four months, so if you've hit rock bottom with quality of your hair like I had, this could be the miracle you need."

Prudence Wade tried: Schwarzkopf Professional BC Fibre Clinix, from £20, available at salons nationwide from September 11. Visit Believeinconfidence.com to find your nearest salon.

"For just £20, I'm really impressed with the results. For a quick fix, this treatment is perfect before a wedding or event where you want to look your absolute best."

Sam Wylie-Harris tried: KMS Style Primer treatment, which starts from £20 and includes 75ml of product to take home. Available at KMS salons nationwide. Visit KMShair.com to find your nearest one.

"Even wet, my hair felt like silk, and by the time my stylist Jamie had finished blowdrying, it looked like silk too.

"Completed in just over an hour, this is a fast track to first class hair."
