CONDUCTION VERSUS CONVECTION (JACQUI)

I am stuck at home for a few days due to an L4 -5 misalignment….so my great plan of getting a picture of my 4 year old niece Rebecca making her super cute ‘sad face’ over her melting ice cream cone is not going to happen….that would have been a lovely picture as she never fails to do this, she always insists on 3 ice cream scoops and she can never eat it fast enough so invariably sun radiation and a little conduction results in the famous pout and icecream over the floor. LOL


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.

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

    http://www.ted.com/talks/sebastiao_salgado_the_silent_drama_of_photography.html

    Pay attention to what he explains about hair drying at 13:54 min of his talk.

    Cheers and hope you enjoy the video.

  3. 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
