Study Investigates Which Levels of Heat Cause Hair Damage

We’ve come a long way since straightening your hair involved using the same iron you’d use on your clothes, but with all the tools available now, has heat-styling gone too far?

Some of today’s hair straighteners and curling tongs can reach temperatures of 450 degrees – that’s enough to set a piece of paper on fire so it’s no surprise to find that overuse can also lead to hair loss.

As a response, Purdue University in Indiana, America is trying to provide cold, hard facts as to exactly how hot is too hot when it comes to your hair.

Researchers Findings May End Hair Loss from Heat StylingInvestigating heated hair styling

Assistant professor of mechanical engineering, Tahira Reid, is currently leading a team of researchers who are investigating the tipping point temperature from which different hair types can no longer recover.  She told CBS news, “We are doing research to understand how does heat move through different hair types. We’re interested in understanding the point at which heat begins to cause permanent structural changes in the hair.

I’m advocating for information that`s empirical, that`s solid and it’s not motivated by any marketing agenda,” she adds. “…I’m not a marketer I’m an engineer that likes truth, facts, data.

The research involves subjecting different racial hair types – Afro, Asian and Caucasian – to the types of cleansing and styling rituals people would carry out at home, or have done in salons, then recording each outcome. In order to establish these differences, the team are using methods which are generally employed for strengthening the composite materials used in ropes.

Hair loss from heat styling

When the hair is constantly subjected to intense levels of heat – whether from styling tools or even from a hairdryer – it can become brittle and dry. This can lead to hair breakage which is where the hair snaps along its shaft, giving the appearance of frizzy, thin hair. Whilst it is not a desirable situation for anyone, those with thinning hair should be particularly careful to avoid this type of styling damage as it can make the hair look even more sparse.

This type of breakage is not actually a hair loss condition as it involves damage to the shaft rather than the hair follicle. In extreme cases, a hair loss specialist may be able to help but there are also effective steps for dealing with minimal-to-moderate breakage yourself.

Hair VitalicsThe best way to manage this is to first stop any unnecessary heat styling and if you must blow dry your hair, use a heat protecting product first. Secondly visit your hairdresser for a good haircut that can get rid of any split ends caused by breakage. This does not necessarily involve having to cut your hair short – a common misconception – as layers and feathering techniques can also provide the same benefits whilst keeping length.

Lastly, aid your hair’s recovery by ensuring it gets constant nourishment. This can be done both topically, by using intensive strengthening conditioning treatments, and from within by taking specially targeted dietary supplements such as Hair Vitalics which deliver the necessary nutrients for hair health, helping to build up its strength and vitality. Regular use of an LLLT device like the HairMax LaserComb can also help to promote hair growth.

As the Indiana research is on-going, as soon as we have the report of their findings, we will publish this information here on the Belgravia blog so do check back for updates.
