Who knows, who cares.
So I went off on a search for an alternative to frothy, foamy shampoos. Head and Shoulders helped a lot but the question remained "Why does this shampoo take away the itch? What is in it that I don't want my body to come into contact with?" After all, it was still foaming and as far as my knowledge goes, foamy is not really good for you.
Enter: Apple Cider Vinegar
I am not going to elaborate on how good it is for you, or the many, many uses it has. All I will say is look for a raw, organic, unfiltered, uncooked, unpasteurised, un-unpleasanted, non-chemical-ed ACV. Oh, and apparantly it has to say something to the effect of "the mother" or that it contains "the mother". It will be a murky brown liquid with a bit of a sediment at the bottom which, of course, is the mother.
Of course, the odour of ACV is not really all to pleasant but the smell dissipates after an hour or so after rinsing your hair with it, but I add some essential oils to my mix that not only smell nice but are also good in mending any issues you may have under your thick wooly rug-at-the-top. Feel free to Google them, or create your own combination.
1 part water (preferrably filtered or boiled or distilled)
1 part ACV
10 drops Ylang Ylang EO
10 drops Rosemary EO
5 - 10 drops Rose Blend EO
Any old plastic bottle (I used an old Pantene bottle. The cap comes off so you can pop it in the dishwasher after a few good rinses, to make sure it is LIKE, TOTALLY clean).
Pour water into the plastic bottle and add the ACV. You will have to work out the measurements of water, but since I was using a 375ml bottle I worked on around 180ml water and 180ml ACV. Just make sure there is enough space at the top of the bottle to add essential oils.
Add the essential oils, replace the cap of the bottle and shake, shake SHAKE it!
How to use
Wet your hair thoroughly, and press out any excess water. Shake your ACV rinse thoroughly before dribbling it over your hair, massaging it down into the roots and scalp.
TIP: Keep your head backwards while dribbling the mixture into your hair otherwise it could run into your face and eyes. It will only sting a little bit when it comes into contact with the eyes (unlike normal shampoo which burns like HELL!) but altogether not a nice one to try and rinse out.
Now leave the liquid in your hair while you take your bath or shower, carefully avoiding running water onto your head until you have finished washing the rest of your beautiful body. Rinse, and pat dry. No need for a second rinse unless your hair is really gunky or full of some chemical off-the-shelf hair product.
