I dare say that those of us blessed with straight hair spend a long time seeking the easiest way to get perfect curls, and those born with a lovely head full of waves and curls spend a life time taming and straightening - the grass is always greener isn't it!

I am one of the straight hair ladies who goes through phases of craving curls. Even though I love the results of tonged hair, I am a little fed up of the amount of time and effort it takes to use them and decided there must be an easier way. I decided I would invest in some heated rollers, thinking they may just be the answer to my hair prayers...

- Why Tresemme ?
No other reason than the price.These rollers were half price at Argos, bringing them down from £40 to £20. Not only did I think this was a good deal but it was also about the price I wanted to pay for my first set of rollers. I didn't want to fork out loads of money if I didn't like the results; I'm glad I did this now. Also, as a cherry on the cake, Tresemme is such a well trusted brand I almost knew they'd be one of the best before I began.

- Appearance/ease of use
They come in a lovely, compact, lidded case. - great for storage, and keeps the rollers and supplied clips neat and tidy when not in use. Each roller is slotted on to a vertical heating rod, the lid is closed, the unit plugged in an away it goes. There is a small light at the front of the device that indicates it is working, and a small heat light on top of each roller glows white when they have heated up sufficiently. There is also a storage compartment and the front in which to keep the hair clips which secure the rollers in the hair.
Also supplied is a bag of larger black hair grips which can be used instead of/as well as the clips. These open up like a crocodile clip and wrap round the outside of the roller. These can be a bit less fiddly than clips though I think they feel a bit loose and do not hold the hair as securely. The only other drawback to this is that they are supplied in a large clear plastic bag with no permanent storage solution - a simple little drawstring bag would have been nice to be supplied with for this purpose.

Each of the rollers is black in the central, heated parted with grey plastic at both ends which stays cool for handling, rolling and clipping. The great thing is that even if it takes a while to fix in each one, the others remain in their place and stay hot until they are used.

The rollers come in 3 different sizes - small, medium and large. The smaller ones give a tighter curl and are designed for shorter hair whereas the larger one give a looser curl, wave or volume to longer hair.

- The results
I really do think practise will make perfect where these are concerned. After my initial use I wasn't impressed. My hair looked heat damaged, unnatural and basically just a mess. My fairly long hair seemed to bend rather than curl up to about my ear lobe, it looked a bit mechanical in a way.

I have however persevered and given them a few more chances. I have learnt not to leave them in for as long. I thought that the longer I left the roller in, the more defined the curl would be, but to be honest it doesn't seem to work like this. Also, the curls I made tended to drop out within 2 hours, but perhaps some curl defining mousse would solve this problem. It seems to be a bit of trial and error with the length of time and the size of rollers to use, but to be honest this is more an issue with me as the user rather than the product itself. I think I was expecting to have a headful of curls that would suggest a lengthy tonging session from just 20 rollers

Having not used a different heated roller product I can't compare it to another one, but it does seem to do what it claims to do and is very simple to use.

The instruction manual it is supplied with is very good and clear. It tells you exactly how to use the product and how to care for it. It's also supplied with a mini magazine-style booklet with pictures of hair ideas and the different looks that can be created from the different sizes of roller which made a good read.

The product is good, it's more me as the user that should have done my research a little better. For that reason I give 4 stars as I think Cosmopolitan have a good creation here, it just isn't for me.
