This is the second post in the 'Sisterlocks Appointment Etiquette' Series - but to be honest these are principles that can apply to any personalised Hair service.
Let's talk about clean hair. Of course, if your hair appointment/service is for a 'wash and set', 'wash and retwist', 'wash and condition', 'wash, detangle, condition' or similar variation etc' this doesn't really apply to you.
One of the questions I am frequently asked by prospective clients is :
"Why do I have to wash my hair within 24 hours of my appointment?"
BackgroundWithout wanting to get too deep into the science - suffice it to say that there are 5 layers of skin and the skin we can actually see and feel is the outermost layer of the epidermis known as Stratum Corneum which is constantly shedding as the cells are damaged and die.
Like skin anywhere else on your body, your scalp sheds dead cells every day - a process known as 'desquamation'. (Superstock has a really cool microscopic image of the skin and hair where some shed skin is visible - but it is copyright so I can't reproduce it here but you can click this link to have a look. Click here to see an image by the Science Picture Company which shows skin and hair without debris.)
These shed cells can accumulate and manifest itself as a layer of debris at the surface and needs to be removed by shampooing. Since our skin cells contain lipids and these mix with the naturally occuring oils (sebum) on our scalp - simply brushing or rubbing the scalp will not completely remove shed cells - you need the aid of a surfactant like shampoo to help dissolve the fatty content and properly cleanse the scalp.
It is important not to confuse this normal shedding with dry scalp, dandruff or scalp eczema.
Now add to this 'normal' desquamation - any environmental pollutants: dust, pollen, microscopic bugs (blown in by the wind while you were walking through the park) and even tiny particles of lint suspended in the air and you can see that without a nice wash the chances of your scalp or hair being truly clean are very low. (This does not mean that your hair will LOOK dirty, in fact it may actually look CLEAN but the particles are there).
How is this relevant?Scalp Debris:
|excessive scalp debris on protective cape|
I always cover my clients with a hairdressing cape to protect their clothing but if the scalp debris is excessive this won't prevent particles of dead skin cells from transferring to my own clothing, the floor and the air (and therefore my eyes and nose) while I am working on you.
Interlocking is a manual and repetitive process so it is inevitable that tiny particles of debris will be disturbed and dislodged from the scalp during retightening and if this debris is significant it will become noticeably embedded in your locs. Do you really want that?
If you retighten hair that contains a significant amount of shed cells, oil (natural sebum or added plant oils), dust, pollen etc - you will cause these pollutant particles to become a permanent feature of your locs as they will become 'permanently' embedded as the dreaded 'build-up' or 'lint-up'! Do you really want that?
An ACV soak can help dissolve accumulated build up and using a tweezer to pluck out strands of lint can be fairly successful in redressing these problems but prevention is always better than cure.
The image below shows trapped lint in a lock. It is used for illustrative purposes only and does not mean that the lock rocker retwisted her hair while it was dirty etc as lint can be attracted to locs from our pillows, clothing, sofas etc. I'm just saying that retwisting/retightening unclean hair will lead to trapped lint/dirt and will make things worse if you already live in a very fluffy environment and this is a very good picture of trapped lint.

SummaryIf you have washed your hair and scalp with the correct techniques within 24 hours of your appointment then chances are there'll be no or very little debris on your scalp when we begin your retightening session as we will have eliminated most of the naturally occurring desquamation and any product or environmental build-up as well. This in turn will help maximise your chances of having debris, lint and build-up free locs in the long term.
Q: Why do I need to wash my hair within 24 hours?
A: To cleanse hair and scalp and keep your scalp free of naturally occurring desquamation prior to your retightening session. (Remember - skin cells shed EVERY day.) Commit this bit to memory: This in turn will help maximise your chances of having debris, lint and build-up free locs in the long term.

Until next time my lovelies,
Feel better. Be well
