The difference is not in the name on the box, but in three practical signs you can notice before anything touches your skin:
A practical tip for occasions: the design is often applied in a crowded room hours before the wedding, which is not a good moment for a debate. Ask days in advance, request natural henna explicitly, and test a small patch on your forearm the day before if you are using a new product. And open a window or sit somewhere well ventilated if you are sensitive to smells — common in pregnancy.
A separate rule: no henna for newborns
In many regions it is common to put henna on a newborn's hands or feet. This custom deserves a frank pause: in children with G6PD deficiency — relatively common in our region and known to some as "favism" — applying henna has been linked to red blood cell breakdown and severe jaundice that can require hospital admission. The difficulty is that the deficiency often goes undetected until something happens, and you may not know your child has it. So the recommendation is simple: leave henna off newborns and infants entirely. There are many other ways to celebrate that carry none of this risk.
Myth Black henna is just henna in a darker shade — as natural as the red kind, only prettier and faster.
Fact Black henna is not a type of henna. The fast black colour comes from a chemical, PPD, which is permitted in hair dyes at low concentration and rinsed off — but applying it directly to skin and leaving it for hours is an entirely different matter. Documented outcomes include chemical burns and blistering in the exact shape of the design, and allergic reactions that can appear days later and leave permanent discolouration or scarring. Worse, PPD sensitisation is lifelong, so you may not be able to use ordinary hair dyes afterwards. This is not only a pregnancy issue — black henna is avoided always and by everyone, including children.
When to ask your doctor
See your doctor if severe redness, itching, blistering, or ulceration appears where the design was applied, whether immediately or days later. Seek urgent care if it is accompanied by facial swelling or difficulty breathing. Also ask your doctor if you have a known allergy to hair dyes, or eczema or broken skin where the design would go. And if henna has been applied to your newborn and they develop yellowing of the skin or eyes, lethargy and refusal to feed, or dark urine, seek medical assessment immediately and do not wait.
