Do you know the price of beauty? Often, it has nothing to do with money. The rising awareness of health has made natural products all the rage.
Even henna hair dye is becoming more popular. But plant-based doesn’t equal fool-proof, so it’s vital to do your research. Here’s what you need to know before using natural hair dye.
Henna Versus Commercial Hair Dye
It’s no secret commercial dye is full of chemicals! First, ammonia and hydrogen peroxide lift your original hair color. You’ll need a lot more if your hair is dark. Next, colorless aromatic amines react with hydrogen peroxide. This interaction creates a pigment, but darker colors need higher concentrations of aromatic amines.
But the effects don’t stop there. Regular hair dye use is linked to cancers of the bladder, breast, bone marrow, and blood.1 It can also cause hair breakage, dryness, skin

If you already got a dye job, the color needs to be lifted up. This calls for at least one more round of bleach. Over time, it’ll change the structure and strength of your hair.
3. You Want To Use Black Henna
Hold that thought! Black henna should be avoided completely. It contains para-phenylenediamine (PPD), a potent allergen linked to contact
PPD is used to intensify color and reduce drying time,8 but the risk isn’t worth it.
