If your henna paste is too watery or runny, adjust the mixture at once. Follow the following steps to make your henna less watery and thicken it:
- Mix your henna paste thoroughly in order to break up any clumps of dry paste.
- Add 1 tsp of henna powder to the henna paste.
- Stir the henna powder into the paste, mixing it thoroughly.
- Check the consistency.
- Repeat the process if necessary, adding the same quantity of henna each time and mixing until the paste is thick and no longer watery.
