#blackhenna

Questa è una vecchia foto della mano di mia madre, ricoperta di Henna naturale.

L’Henné o “Al Henna” ( in arabo الحناء ), può essere una bella alternativa ai tatuaggi permanenti! Nella sua forma più naturale, infatti, è adatta ai bimbi e alle donne in gravidanza (consultare sempre il proprio medico).

MA ALT ! 

Non è però il caso delle foto aestethic che troviamo su Pinterest o Instagram che ci mostrano bellissime dita affusolate adornate da questi bianchi, rosa o neri ghirigori. Infatti, queste colorazioni sono date da sostanze altamente tossiche per la tua bellissima pelle e non solo.

 Tra queste troviamo:

Clove Oil (olio di chiodi di garofano) e Mustard Oil (olio di senape): possono causare severi bruciori e irritazioni.

Mehandi / Mehndi Oil: non è mai specificato cosa si trova al suo interno, proprio perché solitamente è formato da un insieme di sostanze “misteriose” e low quality in India, including cherosene e benzina!

Ammonia (ammoniaca).

Sodium Picramate (picramato di sodio): clicca qui per saperne di più. 

Metallic Salts (sali metallici): utilizzati in quasi tutte le tinte per capelli, non vanno d’accordo con altri prodotti chimici. Dunque, se colori i capelli con una tinta di questo genere, sarà molto difficile per te, in futuro, passare ad un'altra colorazione! Le reazioni avverse ad altre sostanze chimiche potrebbero seccare, bruciare o sciogliere i tuoi bellissimi capelli.

Paint thinner (diluente): se ti trovi in Marocco e vuoi provare al Henna, chiedi se contiene “doulio”. Se la risposta è positiva, potrai sicuramente provarla altrove! Non vorrai rischiare di bruciarti, ain’t you?

P-Paraphenylenediamine / PPD: clicca qui per teletrasportarti sul sito del NHS nel Regno Unito, dove troverai approfondimenti e consigli al riguardo. 

 Come riconoscere una fake Henna da una real one?

Controlla su questo sito che l’artista consigliat* sia presente. 

Al Henna in coni con stampe particolari va evitata, poiché indica che è stata prodotta in una fabbrica. Se la miscela è al 100% naturale, va conservata in freezer. Proprio per questo motivo è sconsigliato ordinarla già pronta dall’estero.

Se l’etichetta della tua confezione di Henna non contiene la lista degli ingredienti e, se una volta aperta senti odore di chimico, ammoniaca o gas, è il caso di buttarla.

Il tempo di asciugatura va oltre le 3/4 ore. Se leggi “instant Henna” sull’etichetta, allora è troppo rischioso.

Listen, non importa se la utilizzi da tempo e/o non ti ha mai causato danni, perché alcuni sintomi possono comparire a distanza di anni e possono essere fatali! I care for you. Se vuoi approfondire e non provi impressione guardando certe foto, click here, here, here and here.

I love that black nail polish life, but my fragile nails always end up flaking away in retribution. A few days ago I tried dying my nails with black henna*, and I ended up with the semi-matte black ombre manicure of my dreams! It’s definitely more of a commitment than polish, but let’s be real, my nails were going to be black one way or another. I thought I’d share, and ask if anyone else had tried this.

*Black henna isn’t just henna- it almost always includes paraphenylenediamine (PPD), which some people are very sensitive to. Always patch test, especially with black dyes! If you're concerned about the chemicals, you might try using a combo of indigo and traditional red henna to get a black effect (note: I have not yet seen this work. It usually just looks like VERY blotchy bruises).

How-to instructions below

------------------------------------------------

DISCLAIMER: Please patch test any black henna 48 hours before you try this, especially if you have chemical sensitivities.

UPDATE: Common advice is to patch test before each application since sensitivities can develop, but since I dye every few weeks, I just minimize skin contact with the stuff. 

Here’s how:

Get a black henna powder or paste. I used this one. It’s cheap, but you get 10 packs of powder, so maybe consider gifting some to friends. The dye will begin to react with water in the air after the packet is opened, so I usually section a packet out into little mini airtight bags when I open one, which helps keep the powder fresh for longer.

Patch test 24- 48 hours before application. Don’t skip this. You don’t want contact dermatitis on your hands. I took this as an opportunity to dye my pinky toenail to make sure I liked the finish and color.

Prep nails: they should be very clean, and you should carefully push your cuticles back. Make sure there’s no dead skin on your nail surface. A wipe down with isopropyl will help remove lingering oils.

Mix a little bit of the powder with water. It should be a paste, a little thicker in viscosity than regular polish. Apply quickly after mixing.

Use a small clean brush or orange stick to carefully paint a solid layer over your nails. Avoid the cuticle, as the dye will stain your skin. Try to get an even layer, and go all the way to the cuticle without actually touching it. I usually do a light coat and then go over it once it’s dried a little, and the texture of the first coat will allow the second coat to stick. Basically, paint your nails. 

Let sit for a half hour - 45 min. It should dry in ~20 min, but until then be careful not to get it on anything else. EDITED 2023: After the paste dries, paint on a thin layer of mod podge. Once this second layer dries, you can use your hands (carefully, and avoiding water) as normal. Best results reached when it sits for 1-2 hours at least. 

Wash off under warm water. With a lighter coat, your nails should be a deep black at the tips and fade towards the cuticles. A thicker coat will result in more solid color and longer eear. Reapply if you missed any spots.

Enjoy, and treat your nails nice! Use a nail oil or other moisturizer that you wouldn’t have been able to apply if your nails were covered in polish. 

Maintenance: The first time I applied the dye, it was pretty faded after a week. After another application, there was much less fading. Now I just re-apply when my nails grow out too much. I’d also recommend switching off which hand you do first, as the dye seems to be most effective in the first few minutes after water activation.

Growing it out: This is not temporary, BUT it was easier to get rid of than I expected. After dying for a month or so last year I decided to go back to natural nails. There was an awkward week or so where the dye was too far towards the tip to look intentional, but pretty soon I was able to buff off the color. The ombre effect also softens the grow-out look. I had a bit stay on one of my thumbs where a ridge had formed, but other than that the grow out process was pretty painless. It would also be easy to paint over the growing out nails with trad polish or gel. 

IMPORTANT TO NOTE:

1) This is not temporary

2) It’s not going to be a glossy black. It’ll be the exact texture of your nails. Use a cuticle/nail oil to increase shine (and healthy nails). You could try buffing before you dye if you really want a smooth surface.

3) If your nails flake or get scratched, the color will come off. I sometimes have it wear off on the very tips of my nails

4) Maybe don’t bite your nails. PPD is not the worst, but it’s not great. I try to minimize all skin contact with the dye while wet, scrub the residue off very carefully, and I don’t bite my nails. If you have a nail-biting habit, this might not be a great option for you. 

After about 2 weeks of fade/growout:

The color holds up pretty well, especially after repeated dyings. However, you can see spots where my nails themselves have chipped or scratched.
