Amazon Prime Day has put the ghd Platinum+ straightener on my radar with its colour-protecting technology

If there is one hair tool I would always pay attention to during Amazon Prime Day, it is ghd. The brand has long been a salon favourite, and the ghd Platinum+ is one of its more advanced straighteners, combining predictive technology with heat control designed to protect colour vibrancy.

The ghd Platinum+ Smart Hair Straightener & Styler is currently included in a limited-time Amazon deal, making Prime Day an interesting time to check the price of a premium styling tool that would normally sit firmly in the investment category.

What makes the Platinum+ different from a basic pair of straighteners is the technology inside it.

ghd's predictive technology is designed to recognise the thickness of your hair and how quickly you are styling, while the ultra-zone heat control monitors the temperature and adjusts the power as you move through your hair.

The Platinum+ maintains an optimum styling temperature of 185°C, rather than simply relying on increasingly high heat to create a sleek finish.

For anyone who colours their hair, that is particularly interesting. ghd says the Platinum+ provides 2X more colour protection compared with a styler operating at 230°C, with the technology designed to help protect colour vibrancy.

As someone with a hairdressing background, temperature is one of the first things I look at when considering a styling tool. A straightener does not necessarily need to be as hot as possible to create a smooth finish, and having technology designed to control the heat is a feature I can understand the appeal of.

The ghd Platinum+ is also designed to do more than straighten hair. Its rounded shape makes it possible to create waves and curls as well as sleek styles, giving you more options from one tool.

The floating plates are designed to glide through the hair, while the wishbone hinge helps keep the plates aligned as you style. ghd also claims the Platinum+ can deliver up to 75% more shine compared with naturally dried hair.

There are practical details too, including a 2.7m swivel cord, universal voltage for travelling and an automatic sleep mode that switches the tool off after 30 minutes without use.

Amazon currently lists the ghd Platinum+ as an Amazon's Choice product, with more than 100 bought in the past month and 70 customer ratings showing on the product page.

It is worth keeping an eye on the price during Prime Day, particularly if you have been considering investing in a premium pair of straighteners but have been waiting for a more appealing opportunity to buy.

For me, the colour-protection angle is what makes the ghd Platinum+ Smart Hair Straightener particularly interesting. It is not simply about getting straight hair. The technology is designed to control heat while still giving you the versatility to create sleek, wavy or curly styles.
