1. Begin by choosing the right henna for your hair coloring needs. Choose a product that contains pure, natural henna powder, or an herbal-based henna dye, as this is safest for your hair and scalp. Be sure to read the instructions carefully before selecting a product.
2. Prepare the henna powder in advance by mixing it with an acidic liquid such as lemon juice or tea water to create a paste. The ratio of powder to liquid will vary depending on the brand of heena you are using, so be sure to check the instructions before preparing your paste. For most products, it’s best to mix about 2 parts henna powder to 1 part liquid for a thick paste that will coat your hair evenly when applied.
3. Once you have prepared the paste, cover it with plastic wrap and let it sit for about 4-6 hours or overnight so that it has time to properly develop its natural coloring agents (dye).
4. To apply the paste to your hair, start at the roots and gradually work your way up towards the tips of each strand of hair. Wear gloves while applying to avoid staining your hands with henna dye.
5. Cover all strands of hair completely with the paste and leave on for 1-3 hours, depending on how deep of a color you want to achieve and how porous your hair is. Check periodically throughout this process to ensure you get even coverage across all strands of hair.
6. Rinse out henna dye completely with warm water until no trace remains in your shower or bathtub drain. If any traces remain after rinsing thoroughly, try scrubbing them away with a dry cloth before moving onto step 7 below.
7. Condition and moisturize hair after using henna dye as this will help keep moisture locked in from root to tip and promote healthier looking tresses over time. You can do this either by using an all-natural conditioning treatment or store-bought conditioner formulated specifically for coloured or treated hair (such as dandruff shampoo).
8. Dry and style as desired after rinsing out all of the henna dye and applying conditioner; henna should not interfere with heat styling methods like blow drying or curling irons as long as you don’t leave them on too hot/long!
