How much Henna / Indigo do I need?

Hair Colour Advice : How much henna for hair / indigo do I need to use, and how long do I leave it in for ?

It depends how long and how thick or fine your hair is. As a general rule of thumb, I suggest these quantities for “normal” hair, but I would say to reduce these quantities by about 10 – 20gms for really fine hair, and double the quantities here for really thick hair : If you’re in a country that doesn’t use grammes, sorry, just try to adjust according to the weight of the pack , eg 50gms = a quarter pack of the 200gms bag of henna, 100gms = half a pack & so on ) :

  • short / chin length hair – 50 gms henna / 30 or 40 gms indigo
  • shoulder length hair – 100 gms henna / 70 or 80 gms indigo
  • mid back length hair – 200gms henna / 140 or 150 gms indigo
  • hip length hair – 300 gms henna / 210 or 220 gms indigo

Roughly, I would advise to leave henna in your hair a minimum of 2 hours; the process can be speeded up by use of a hair drier, set to a moderate heat setting, if you’re in a real hurry. How long you leave the indigo in for depends how deep a colour you want. It varies from say 10 minutes to 2 hours, or even longer if you want ! Ten to fifteen minutes will be sufficient to change your rich reddish henna tones to a muted brown hair colour ; half an hour would give you a really deep brown black hair colour ; an hour would give you black hair; 2 hours an intense deep raven black hair colour. You get the idea anyway. To start with, if you’re aiming for brown hair colour, leave the indigo in for ten to fifteen minutes and no more. Then you can determine if you need to leave it in for a longer or shorter period the next time round. You’ll find it useful to study the hair colour gallery photos and note how long each person applied henna / indigo in their hair to get the hair colours shown in the hair colour pictures.
