Here’s a fun fact for you: a single bolt of lightning has enough energy to toast 100,000 slices of bread. Yet we continue to use fossil fuels as our main source of energy in the industrial and technological sector. Why, I hear you ask?
Without going into specifics, mainly it’s because fossil fuels are more dependable, we know where to find them and how to harness their energy to continue our industrial endeavours. The same cannot be said for lightning.
Here’s another one, more germs are transferred through shaking hands than kissing. True story. Yet you can bet your sweet behind that I will not be kissing my weird cousin Fred at our next family gathering. He will have to make do with my handshake.
Point is that science has a lot of answers to give us about aspects of our physical world and that includes our hair too. It can tell us how hair grows, it’s makeup in the molecular sense and even how it reacts in different environments. But not all scientific findings are easily transferable to real world situations. Here are few examples of situations in hair care where science clouds the issue when growth and length retention is the focus of your regimen.
Rates of hair growth
I’ve covered this topic in a previous post but to give you the cliff notes, we all hear over and over again that 6 inches of hair growth is what the average person should expect in any given year of hair growth. But the truth is actually more complicated than that.
Think about this, we accept that in hot summer months some of us will invariably get darker but to what degree? Some people get darker tans than others even exposed to the same amount of sunshine and others don’t tan very easily at all, they may just turn red.
In real life, rates of hair growth vary widely depending on genetics among groups of people, nutrition density of the diet or even environment. So the average rate of growth is mostly a suggestion, not a fact.
How long to deep condition your hair
Ever wonder why many bottles of conditioner say that you can rinse it out after two minutes? Well some cosmetic scientists and cosmetologists will tell you that conditioners don’t do much good to your hair after the first 2 minutes.
Others still say that a 1/2 hour is the maximum time that they should be left in your hair because absorption rates diminish after the first 30 minutes. Well that may be true in a lab environment with a handful of subjects but does the same hold true across the board for every single hair type, texture and porosity level there is out there? Errrm no.
We see this all the time, the women getting the best length retention are those deep conditioning(affiliate link) for a hour or so every week. Its not rocket science, if your hair is low porosity you need to deep condition longer but if your hair has medium to high porosity, you can get away with shorter deep conditioning(affiliate link) times.
