Why You Need It
- Natural Cooling: Henna generates a distinct cooling sensation when applied, helping soothe hot, inflamed skin.
- Hair Health: It coats the hair shaft, acting as a natural conditioner that adds shine and volume.
- Skin Protection: It creates a protective barrier against environmental damage and minor abrasions.
- Antimicrobial: It naturally helps keep the skin clean and free of unwanted microbes.
Deep Dive
Henna's magic lies in a compound called lawsone. This molecule loves binding with the keratin in your skin and hair. When you apply the paste, lawsone migrates to the top layer of your skin or the cuticle of your hair, sealing it up. This is why it strengthens hair and makes it glossy. For skin, the astringent properties help tighten pores and dry out minor irritations, which is why it has historically been used on feet and hands to prevent blisters and cracks. It’s a physical shield that lets your body heal underneath.
Natural Food Sources
Henna is a botanical leaf, not a food source. It is traditionally harvested, dried, and ground into a powder. It is inedible in its raw form and is never consumed as a dietary supplement.
Supplementation
Since Henna is not absorbed systemically (it doesn't enter your bloodstream), you do not 'supplement' with it like a vitamin.
How to use it:
- Body Art: Mix the powder with lemon juice and sugar to create a staining paste.
- Hair Mask: Mix with water or yogurt to create a conditioning paste. Leave on for 1-3 hours.
- Cooling Paste: Mix with water and apply to sunburned or hot skin (do not use on broken skin).

Safety & Side Effects
CRITICAL SAFETY WARNING:
- NEVER INGEST: Henna is toxic if swallowed. It can cause severe stomach upset and other serious health issues. It is strictly for external use only.
- 'Black Henna' Danger: Be very careful of 'black henna' used in tourist spots. Natural henna is green/brown and dries brown. Black henna contains paraphenylenediamine (PPD), a harsh chemical that can cause severe allergic reactions, chemical burns, and permanent scarring. Always insist on 100% natural, green powder.
- Pregnancy: While natural henna is generally considered safe topically, always do a patch test first to check for allergies.
