How often should I wash my hair?
Thanks for asking.
When it comes to washing our hair, many of us stick with a specific routine purely
out of habit.
It's not uncommon for people to wash their hair with shampoo every day, which can actually
have adverse effects.
At the other end of the scale you've got those who embrace the no poo movement and don't
use shampoo at all.
The trend really took off during COVID-19 lockdowns, although there is still somewhat
of a stigma about washing your hair too infrequently.
We don't necessarily stop to consider what is really the best option for our hair.
Let's look at how you can avoid doing more harm than good.
How does shampoo actually work?
It traps the excess oil, dirt and product residue in our hair.
Bear in mind that the scalp is an extension of the skin on our face.
That means it collects dead skin cells, sweat and dirt, all of which needs to be cleansed
in order to keep our hair healthy.
When we use shampoo and then rinse, that cleans our hair.
The risk is doing it too often may dry out the hair or even damage it.
What factors should we be taking into account?
The biggest one is how much oil our hair produces.
The oil in our hair is also known as sebum, and it has a purpose which is to hydrate the
scalp and protect hair.
However it can also leave your hair limp and clumpy, giving it a greasy look which people
generally want to avoid.
So the less oil your hair produces, the less often you need to wash it with shampoo.
This varies based on a number of factors like age, sex, physical environment and genetics.
It's pretty closely related to the type of hair you have.
The only people that really need to wash their hair daily are those with very fine hair.
They have more individual hairs on their head than others, and of course each hair follicle
has an oil gland attached to it.
So it follows that the more oil glands you have on your head, the quicker your hair gets
oily.
That also means people with thick, wavy or curly hair don't generally need to wash their
hair as often.
How will I know it's time to wash?
On average most people can get away with washing their hair every two to three days, but
it is possible to go longer without washing.
In recent years, hair products which allow you to do so have become more and more popular.
These include powders and leaving conditioners.
How often you wash your hair is really down to personal preference, but dermatologists
say there are some tail, tail signs that will let you know it's time to wash.
These include getting an itchy scalp, noticing that your hair is visibly oily, or feeling
that it's unclean when touching it.
There you have it.
