Very economical and very effective, these recipes are suitable for all hair types, don't cause allergies and even have beauty benefits (volume, coverage of dark roots, etc.).

Introduction

Dry shampoo was relatively unknown before big cosmetic brands like Garnier and others decided to make it a major asset in their cosmetic sales. In fact, that's how I discovered its existence! The promise of being able to quickly and discreetly clean your hair without water at any time, in just a few minutes, seems incredible but true, and can be done without spending a penny more than our kitchen shopping! On average, a bottle of industrial dry shampoo costs around 5€, but if you look at the ingredients you soon realise that you're buying gas, a bit of perfume and starch. Starch!!

So let's take a look at our kitchen cupboards: starch is found in flour (any kind of flour) as well as maïzena (corn flour) or potato starch (very rich in starch, potato flour). If you look back at our recipes and tips for cleaning greasy stains, you'll find a wider range of powders that can be used in dry shampoo: clays, diatomaceous earth, chalk, talcum powder, blanc de Meudon, etc. You can even use very finely powdered bicarbonate for food or cosmetics (but NOT for household use), but this can be a little more irritating to the scalp. And all these powders are 100% natural, normally non-allergenic and 100% biodegradable.

To adapt the base powder to your hair colour, there are several options, the simplest being to mix it with coloured spices (brings colour and a delicate fragrance!).

Matériaux

Depending on what's in your cupboard, you can use :

• Flour, cornflour, potato starch
• clay (avoid green so you don't look like an alien)
• Talc
• Diatomaceous earth, Meudon white, chalk
• Very fine bicarbonate for food or cosmetics (not household)

You can use these products on their own (e.g. wheat flour only) or combine them.

To adjust to your hair colour.

• Blond: nothing, white is enough and even covers dark roots.
• Browns/Chains: cocoa, cinnamon
• Sweet: a mixture of cinnamon, sweet paprika and turmeric (be careful, turmeric can permanently stain fabrics!)
• Black: powdered charcoal
• Other colours: pink beetroot powder, blue spirulina, purple mix of the two... Have fun finding combinations.

Outils

• Bowl + spoon for mixing (if clay, do not use a metal spoon)
• Simple jar OR with salt/spice shaker
• To apply: brush with fingers OR blush brush OR sprinkle with the salt shaker.

Étape 1 - Production

• Place one or a mixture of the basic powders listed above in your small container.
• If you need to adapt the colour, mix with one or more spices to obtain the desired colour.
• Place in the final container

Optional: some people add essential oils. This is not necessary for preservation or hair care. Dry shampoos can be used to tide hair over or replace a few shampoos (to space out the washes) but are not a treatment in themselves. The smell is not essential either (especially if you adapt the colour)

.

If you really want to use essential oils, bear in mind that they are not perfumes, but medicinal concentrates of powerful plants (check the recommendations for use and test your skin reaction before use in a product) which require a significant amount of plant resources and energy. If possible, use local essential oils.

Étape 2 - Preservation

It is recommended to preserve the powder in an airtight jar, but this is not obligatory. Simply shake well if any lumps have formed due to humidity. If you have food moths in your home, use an airtight jar and/or powders not made from flour.

Étape 3 - Use

Instructions for using :

1. Sprinkle the dry shampoo in small doses at the roots, staggering the strands zone by zone if you want to wash the whole head.
2. Massage into the scalp to homogenise the powder and bring it into contact with the sebum.
3. Wait between 3 minutes (express effect) and overnight (deep effect).
4. Shake, rub and brush the hair to remove the excess powder and limit the dull/matt effect.
5. Live your life with your hair blowing in the wind!

Bonus : utiliser un shapoing sec permet de gagner du volume et de donner de la texture à vos cheveux + couvre les racines pour aténuer le démarquage si cheveux colorés + odeur neutre ou parfumée suivant les poudres utilisées

Quelle efficacité?  : Les poudres vont absorber le surplus de sébum des cheveux et l'éliminer lorsque vous brossez/frottez les cheveux. Pour l'effet, tout dépend de la nature de vos cheveux. S'ils sont gras ou très épais, quelques heures. Dans le cas contraire, l'effet peut être visible jusqu'à 48 heures.

Notes et références

Pour les curieux.ses et les aventuriers.ères vous pouvez tenter le no-poo, le fait d'espacer voire de totalement supprimer les shampoings. Cela ne veut pas forcément dire ne plus se laver du tout (certain.e.s utilisent un lavage à l'eau, à l'argile comme le Rhassoul, de l'eau bicarbonatée ou vinaigrée ou justement, uniquement des shampoings sescs). Un des secrets pour espacer ses shampoings peut être une "cure de sébum" c'est à dire laisser ese cheveux gras pendant environ un mois afin que le corps régule lui même la production. En effet, plus vous lavez vos cheveux, plus ils auront tendance pour se protéger à produire beaucoup de sébum et donc à regraisser vite, cercle vicieux. Cela demande un peu de courage, mais avec un confinement/télétravail ou la créativité de bonnets/turbans/foulards, on peut y arriver sans passer pour un.e pestiféré.e.

Plusieurs personnes (y compris des femmes aux cheveux longs) ont tenté et réussi, mais le résultat varie fortement suivant la nature de vos cheveux et votre activité physique. Pour certains une cure permet d'espacer les shampoings de 2 semaines, moi pas du tout!
