So I needed to improvise …this gives me the opportunity of
sharing a secret about type 3b hair with you…patience please! the rule is..... AS MUCH AS
POSSIBLE…STICK TO AIR DRYING 3B HAIR.
I explain….
When dried naturally by conduction…which can take anything
between 2 to 5 hours depending on how hot the weather is the result …nicely
well behaved coif above.
However when the drying process is accelerated by assisted
convection drying using a hair dryer with a diffuser …the results are sooo different! See below!
You are permitted to laugh everyone.
Take care.
Jacqui hi, I loved the way you constructed the story around this. Many thanks, UMIT

DeleteJacqui hi, Your hair drying example of heat transfer reminded me a video I watched in TED talks by Salgado, my favorite photographer.

Pay attention to what he explains about hair drying at 13:54 min of his talk.
Cheers and hope you enjoy the video.

Jacqui, your creativity is not only entertaining but also demonstrates how exposure to various forms of heat transfer can produce different physical outcomes. And that is not something we always think about as we tend to focus on the damaging effects of heat on vaccines and biological materials. But what about the packaging? Plastic materials especially behave differently when exposed to heat with some more tolerant than others. Prolonged or excessive heat exposure can often result in shrinkage and distortion of the packaging. (I will post a photographic example in an email and send it to the group). Thank you for showing us the after effects of heat transfer. - Kevin
